SEO-Friendly Website Design: 12 Criteria You Can Check Yourself

SEO-friendly website design means getting the HTML structure, speed, mobile interface, URLs, meta tags, structured data, crawlability and measurement right from the moment the site is built. You should receive a website that Google can read, buyers find easy to use, and your content team can publish on without having to fix the foundation.

• An SEO-ready website ?
• Why does every business need an SEO-friendly website?
• The benefits of owning an SEO-friendly website
• What are the key criteria for judging an SEO-friendly website? Plus many other questions worth knowing about.

Below, MONA Media shares an overview of SEO-friendly website design, the evaluation criteria and the benefits of building a professional e-commerce website, SEO-ready for businesses across many industries.

Overview of SEO-friendly website design

Before getting to SEO-friendly websites, MONA will give you a quick overview of SEO is the process of optimize a website to rank high on Google's results page. Google uses its own scoring system to evaluate websites based on hundreds of criteria such as: content quality, user experience and trustworthiness.

Here is a real example to make SEO easier to picture: when you search “cách làm bánh flan” (how to make flan), Google will prioritize websites with detailed recipes (such as step-by-step instructions with tips to keep the surface smooth), high-quality close-up photos/videos of the finished dish, fast page loading, compatibility with every device, and positive user reviews.  

Why do you need a professional, SEO-friendly website? The answer is:

• 99% of users today search for information before buying.
• 73% only trust the top 10 websites on Google.

SEO-friendly web design is the process of designing a website that meets Google's ranking criteria. An SEO-friendly website is built to help Googlebot easily crawl and evaluate the quality of the content on your site. As a result, Google notices the website and prioritises ranking it in TOP Google positions in the search results, helping the business extend its brand reach online, reach more prospects and increase its conversion rate.

A professional SEO-friendly website combines:

• Exclusive design: An eye-catching design in your brand colors that is modern, professional and on trend.
• Modern features: Technology solutions designed specifically for your business model, nothing more and nothing less.
• Simple to operate: The website management and online marketing system is smartly designed and easy to use, even if you are not a tech expert.
• 100% SEO-friendly: Fully meets all 20 SEO criteria (2026), from the code structure down to every image and word on the website.
• Optimized content: Useful, SEO-friendly pages that help users and are easy for Googlebot to crawl.

Your website is the first place customers decide whether to trust your business, not just a page that introduces it. The video below explains why an SEO-friendly website with genuine content about projects, client reviews and the working process is key to improving conversion and standing out.

Benefits of SEO-friendly website design services

Everyone knows that professional web designers, when it is SEO-friendly, helps customers find your website on search engines ahead of your competitors. Achieve just that and you are already halfway to building your brand online. Look closer, though, and SEO-friendly website design brings far more value than that, such as:

• More visits , more calls

         → Every keyword that reaches the top of Google brings you more interested customers.

• Higher brand awareness

         → Your brand gets noticed across every corner of your industry.

• Revenue growth

         → A large number of prospects who already have a need will come straight to you first.

• Clear metrics that show what is working

         → The numbers show clearly how your marketing is performing, so you can build a suitable long-term marketing plan.

• Connected growth

         → Connect all your social media and e-commerce marketplaces to improve marketing results across every channel you have.

When starting a website, many businesses are tempted by offers of “unbelievably low prices”. Only once the website goes live do they realize the real cost is much higher. The site keeps breaking, loads slowly, throws 404 errors, looks unprofessional, or does not even display correctly on phones, so customers leave after just a few seconds. On top of that, the website is not SEO-friendly, so the business misses the chance to reach the top of Google and spends more to fix it or rebuild from scratch.

If you are choosing a web design company, take a moment to think: Is “cheap” really cheap if you pay for it with your own reputation and business results?

MONA's case study shows clearly what an SEO-friendly website can do. After just 6 months, the website of our partner Hưng Phúc Khang reached the top spot on Google and was attracting more than 42,000 visits a month. Those results come from an effective SEO strategy, and also from investing seriously in a professional website from the start. Below, MONA walks through how this project was turned around.

SEO-friendly website design services at MONA Media

If you have already completed the sitemap, content and acceptance criteria yourself, MONA takes on exactly the missing parts instead of making you redo everything. We break the scope down by page type, features, data to be entered, external integrations and post-handover responsibilities. The quote clearly states what is ready-made, what is custom-coded, which accounts are handed over and which milestones you need to approve. We send back the scope sheet before the design stage begins.

The package in the earlier materials includes pre-project consultation, an SEO-friendly website foundation, UX/UI design, a custom interface within the agreed scope, features matched to your business model and admin training. Clients on the all-in-one package receive a 1-year international domain offer and 1 year of hosting. The scope of the offer, the hosting configuration, renewal terms and the price after the first year must appear in the quote; read those four lines before you sign.

MONA was founded in 2016 and has delivered 14,000+ projects, with 85% of clients continuing to work with us. These numbers do not replace acceptance testing. You still use the 12-item checklist above to check the website, and keep ownership of the domain, admin accounts, measurement data and a copy of the source code as agreed. We still have to hand over every account along with test evidence before the handover meeting.

The timeline is set once both sides lock the sitemap, the number of interface templates, the features and the amount of data to be entered. We do not attach one shared deadline to every website, because a 7-page company site and a system with payments, inventory and permissions cannot run on the same schedule. Every handover milestone must have an output you can check: structure, wireframe, interface, test website, bug check and admin guide.

You do not need to hire anyone yet if the website is small, the launch date is flexible and someone can commit 60 hours to the build. When the launch date is fixed, forms are your main source of leads, or the website has to connect to a process that is already running, the fee buys you someone responsible from structure through testing. That is when a quote should be compared with the 16,602,320 VND of in-house resources in the example, rather than just with the price of a theme. We only take on additional work that both sides have clearly broken down in the scope sheet.

For MONA to break down exactly what needs doing, send us your sitemap, three reference websites, a feature list and your target launch date. See website packages from MONA Media or call 1900 636 648. We will send back the scope, quote and approval schedule so you can check every line before deciding SEO-ready website design. We do not ask you to buy back work you have already done and accepted yourself.

Many businesses spend tens of millions of VND on a website, only to end up with a page that is almost “invisible” on the Internet. With no traffic, no customers and no revenue, it is just a forgotten business card. The cause is a website that is not SEO-friendly, loads slowly and is hard to use, so the business misses the chance to reach customers online

MONA Media's SEO-friendly website design service is built to fix exactly these “pain points”: it gives businesses an online platform that actually works, looks good and is fully optimized for search, experience and conversion.

Beyond that, MONA puts care into every small detail of planning and design, aiming to give clients a website with all the key strengths, such as:

• A design with a strong brand identity: Every website MONA builds has its own identity, truly reflecting the business's character through carefully planned graphic details.
• SEO and UX/UI done right: Beyond making the website SEO-friendly, MONA also makes sure users get a smooth, easy-to-use web experience optimized on every platform.
• Built to HTML5 and CSS3 standards: Using HTML5, CSS3 and Responsive design, your website runs reliably on every device and browser, with no interruptions.
• A full set of modern features: From online payments and ordering to API integrations, MONA builds what your business needs, turning your website into an effective growth tool.
• 24/7 technical team: Ready to resolve any issue, backed by strong security that protects you from cyber attacks.

The latest 20-point checklist for SEO-friendly web design (2026)

Below is the latest 20-point checklist for SEO-friendly web design in 2026, updated to reflect Google's current requirements and user experience trends:

• All the key Onpage & Offpage SEO criteria
• The process for optimizing SEO-friendly articles
• Top SEO tools

1. HTML structure

This is a standard website HTML structure

<head></head>
The section declaring meta tags, title, CSS and JavaScript libraries…

<body></body>
The section holding the page content, where content is displayed (the part highlighted in white)

The <body> content of the structure above is displayed as follows:

The content structure (H1, H2, H3, H4) must follow this diagram:

How to check the HTML structure & content structure of any website

Use these 2 Google Chrome extensions:

HTML5 Outliner 

Lets you quickly check all the Headings (H1, H2, H3…) and Sections of a website.

SEOquake 

This is a more in-depth checking tool than HTML5 Outliner, giving you more metrics and data about the website. SEOquake is very useful once you have some SEO experience.

Today's SEO tools take time to learn in depth before you can use them effectively. Building an in-house SEO team is not a quick fix either; it usually takes at least 3 months for the team to get up to speed, roll out a strategy and start delivering results.

However, if you work with a reputable SEO agency, your website can reach the top spot on Google within that same period. With deep experience, a good understanding of the algorithms and a professional workflow, agencies help businesses save time, cost and and achieve strong SEO results.

This is why many businesses, especially those that need to speed up growth, often choose to work with SEO-friendly website design companies or professional SEO services instead of building a team from scratch.

2. Essential tags

Title

The title tag describes the page content to both visitors and search engines.

Meta Description

The meta description tag briefly describes the content of the web page.

• The ideal description length is 140 to 160 characters.
• The description tag should contain the website's main keyword
• The description must be short and concise and truly describe the page content; for a product page you can add words that encourage customers to click.

Canonical

The Canonical tag tells Googlebot that this is the original URL of the page and that it should regularly crawl data at URL this URL.

Why do you need to set a Canonical tag?

For many reasons, several URLs can point to the same page at once, causing Google to crawl the wrong page, and in worse cases you may be penalized for Duplicate Content.

The most common reasons:

Different URLs to support different types of devices

• https://example.com/danhmuc/ao-nam
• https://m.example.com/danhmuc/ao-nam
• https://amp.example.com/danhmuc/ao-nam

One article placed in several different categories

• https://example.com/ao-nam/ao-nam-tay-dai-trang/
• https://example.com/ao-tay-dai/ao-nam-tay-dai-trang/

The serving server has not been configured for http/https/www/non-www

• http://example.com/ao-nam
• https://example.com/ao-nam
• http://www.example.com/ao-nam

Open Graph & Twitter Card

Open Graph (OG) and Twitter Card tags format how content appears when shared on social media. They use meta tags in HTML to define information such as the title, description, image, URL…

• Open Graph: The common standard for Facebook, LinkedIn, Pinterest…
• Twitter Card: Optimized specifically for Twitter, supporting special formats (video, gallery…)

They make posts shared from the website display fully and neatly:

• Attractive image
• Compelling title
• Description
• Clear URL

HTML language

The HTML language tag (language code) declares the language your website uses (English, Vietnamese, Chinese…), giving search engines more information about the website so they can serve content more appropriately. Whichever market you optimize SEO for, declare that language. 

Example: Google will prioritize showing results to users in Vietnam if the website declares it uses Vietnamese with the following code in <html>:

You can check the HTML language tag of any website with Ctrl + U. Thanks to this geographic targeting, your website will rank higher in searches from Vietnam.

3. HTTPS (SSL)

Registering an SSL (Secure Sockets Layer) certificate not only lets users see that your website uses standard security technology, it also ensures all data is transmitted safely and securely. It is essential for building trust with customers and for meeting Google's strict website ranking requirements.

• One of the important criteria that helps boost website rankings
• Protects user data and information
• More trustworthy with a security certificate
• Provides a safe transaction environment for clients

You can quickly tell whether a website has an SSL certificate from the URL address bar in your browser.

4. Mobile-friendly

As more and more users browse the web on mobile devices (smartphones), Google has confirmed it will prioritize indexing websites with a well-optimized Mobile version that loads fast and is user-friendly.

Check your website's mobile-friendliness now, along with Google's improvement suggestions.

5. Robots.txt

The robots.txt file tells crawlers which URLs on the website they can and cannot access.

A website with a robots.txt file is rated higher by Google, and crawling happens faster and more efficiently. This is an important factor in optimizing the website's visibility on search engines.

If you own a new website, the robots.txt file has most likely not been created yet. For websites already running, the file may exist without you knowing. To check quickly, follow the steps below:

• Open a browser window in private mode
• Go to the file's location robots.txt by entering a URL like this: https://*your domain*.com/robots.txt

Example: https://youtube.com/robots.txt

If the website already has the file, you will see the contents of robots.txt like this:

If you do not get a result like the one above, follow these instructions:

How to create & submit a robots.txt file

Step 1. Open Notepad

Step 2. Create the robots.txt file

Step 3. Add the directives you want, following these rules:

• User-agent: Required: this directive specifies which crawler must follow the rules you set below
• (*): Directive applying to all crawlers
• Disallow: URLs that may not be crawled
• Allow: URLs that may be crawled

Step 4. Upload the robots.txt file to the server

There is no automatic tool for uploading robots.txt yet, so you have to upload it manually or ask your website provider for help

Note: The robots.txt file should sit in the root directory on the server so it governs crawling of the whole website

6. Breadcrumb

A breadcrumb is a navigation bar that shows the hierarchical path from the homepage to the current page (for example: Home → Category → Article ). It helps users:

• See where they are on the website at a glance.
• Move quickly between page levels without using the “Back” button.
• Understand the website structure and discover related content more easily.

A website with breadcrumbs gives Google information to classify the website clearly and serve content more accurately

7. Sitemap.xml

A sitemap is a map containing all the URLs of a website (homepage, blog, categories, subpages…) and how those URLs relate to each other.

A sitemap helps search engines:

• Crawl your website more efficiently
• Know which URLs you want to prioritize

8. Page load speed

Page load speed is one of the important criteria Google uses to evaluate and rank websites. When the content quality of websites is about the same, Google prioritises the faster-loading site in search results. This not only improves SEO rankings but also improves user experience and lowers the bounce rate.

A tool to test website speed and get page speed improvement suggestions from Google: Google PageSpeed ​​Insights

What is a good Google PageSpeed score? SGenerally, you only need a score of

• For Mobile: 60/100 or higher
• For PC: 80/100 or higher

9. Image optimization

Optimizing images not only improves page speed but also helps Google prioritize indexing the website and rank it higher on the results page. When images are properly optimized (compressed, in a suitable format such as WebP, and with descriptive ALT tags), Google can easily understand the image content, which increases the website's visibility in related search results.

The benefits of optimizing images on a website:

• Faster page load speed gives users a more satisfying experience.
• More traffic to the website as users find it through image search (Google Image Search)
• Catches readers' attention when they visit the website, making articles more engaging and lowering the bounce rate.
• More leads: images are very important for commercial websites, online stores and product promotion campaigns.

Here are some common, effective ways to optimize images:

Adjust the display size

You do not always need very large images for a blog post.
Recommended image sizes for websites:

• Homepage slider/banner: 1600 x 900 pixel
• Images in blog posts: 1000 x 670 pixel
• Product images: 900 x 900 pixel
• Thumbnail images: when sharing an article: 1200 x 630 pixels

Choose the right format

If you do not need very high-resolution images, optimize the file size so they load faster and save website resources. You can easily optimize image size with TinyPNG or Optimizilla.

• Use JPEG for photos (prioritising small file size).
• Use PNG for images that need transparency.
• Convert to WebP for smaller files while keeping good quality.

Enter alt text

Alternative Text is a short description of an image's content (such as a product image, blog image,…). It is displayed instead of the image if the image cannot load due to connection errors or other technical problems. Alt Text also plays an important role in helping search engines like Google understand what the image shows, improving SEO and the chance of appearing on the results page.

You can edit Alt Text quickly and easily in 2 common ways:

Code HTML

<img src=”url_hinh_anh” alt=”Mô tả hình ảnh”>

Where:

• The <img> is used to insert an image into an SEO web page
• alt the alternative description shown when the image does not display
• Attribute src the path to the image file

Post editor (WordPress)

On a WordPress website, enter the alt text directly in the alternative text box as shown below.

10. HTML/CSS/JS optimization

Regularly checking and optimizing HTML/CSS/JS gives your website

• Faster & more stable performance
• A better browsing experience for users
• Optimized page load time
• Favoured by search engines

Here are the 6 most effective optimization methods:

• Limit DOM manipulation
• Concatenate CSS/JavaScript files
• Load CSS before JavaScript
• Use asynchronous loading
• Avoid using @import
• Do not embed CSS/JavaScript code in HTML files

11. Social share buttons

Linking your website to social media helps:

• Increase website traffic
• Attract a large number of prospects
• Raise brand awareness in community Groups and Fanpages
• Build engagement and support customers

On the website: Show the social media channels the business is active on and regularly share articles to every social platform.

On social media: Always show the website address on the fanpage profile or channel info, and place links back to the website in posts at a steady, planned frequency.

12. Google Analytics

Google Analytics is a leading website analytics tool developed by Google itself that helps users:

• Easily access key metrics that are essential when you own a website.
• Analyze and measure traffic, with very detailed reports on audiences, behavior, conversions…
• Understand the state of your website so you can build an SEO optimization plan or run a more effective Online Marketing campaign.

13. Google Search Console

Google Search Console is a genuinely useful tool for tracking how your website performs in Google Search.

Useful features that only Google Search Console offers

1. Access a wide range of data on traffic from Google

• How often the website appears on the search results page
• Which search queries make your website appear
• How often searchers click through to the page for those queries

2. Get your website crawled faster

3. Check the list of websites linking to your site

You can use GSC to remove links from other websites

4. Fix and improve your website

To optimize performance and improve website quality, fixing issues related to AMP, mobile-friendliness and many other features is essential.

14. URL structure

Using a simple URL structure that gives users complete information improves the experience and makes the website more professional.

If you use WordPress to manage your website, you can quickly change the URL structure as follows

• WordPress in Vietnamese: go to Cài đặt > Đường dẫn tĩnh
• WordPress in English: go to Settings > Permalinks

15. Schema structure

Schema is a piece of Javascript code used to mark up structured data

• Provides data that helps search engines easily access and accurately classify the website
• Websites with optimized Schema structure are served more appropriately, to more relevant target audiences

Articles, images and videos using structured data displayed on Google's search results page

The most common types of Schema Markup

• Company/person Schema Markup
• Breadcrumbs Schema Markup
• FAQ Schema Markup
• Article Schema Markup
• Review Schema Markup
• Recipe Schema Markup
• Video Schema Markup
• Local Business Schema Markup

16. Trang 404

A 404 page tells users that their URL leads to a page that does not exist.

“According to Google's documentation, 404 errors will not affect your site's performance in search results”

Still, it is a shame when a website loses visits because

• The article the user is looking for exists but its URL has changed
• The article has been merged into another article
• A 404 error occurs
• Duplicate content

 Use redirect 301 so you do not miss any traffic

17. Table of Contents

A Table of Contents helps users easily grasp and navigate an article's content.

A Table Of Contents is an important criterion that Google values highly, and it can help the website show Sitelinks on the search results page.

How to create a Table of Contents for a website:

Create a Table of Contents with HTML + CSS

You can easily create a Table of Contents using just HTML + CSS with the following sample code

CSS code

HTML code

If you use WordPress, these are the best free WP plugins for creating a ToC

• Easy Table of Contents  
• Table of Contents Plus  
• LuckyWP Table of Contents  

18. Favicon

A favicon is a small logo shown in a few places in the browser. Those spots are seen all the time, so it helps people recognize your brand.

• On the left of each tab
• Thanh Bookmark
• On the start page

A simple way to create a favicon file that works every time

How to create and insert a favicon file manually

1. Design an image file sized 16 x 16 pixels, 32 x 32 pixels or 48 x 48 pixels…
2. Go directly to the link http://www.favicon-generator.org/ to convert it to .ico.
3. Download file favicon.ico format, then upload it to your website host.
4. Insert the HTML favicon code into the
   <head>… </head> section of the website

Adding a Favicon in WordPress with the default customiser

• Go to Admin Dashboard (Dashboard) →  Appearance (Appearance) → Customize (Customize) → Site Identity
• Select Select Image and upload the Favicon file you prepared

•   Select Publish to save the changes

19. AMP

AMP (Accelerated Mobile Pages) is a tool that lets you create a version of your website focused on improving page load speed and experience and smoother use. According to Google, the faster pages load, the higher they are rated and the more often they appear. 

How to build AMP pages:

• Setting up Google AMP for a website with HTML
• Sample HTML code for a basic AMP page

For WordPress websites, you can set up AMP quickly with these popular AMP plugins:

• AMP  
• AMP for WP – Accelerated Mobile Pages 
• PWA for WP & AMP 

20. Search Bar

Search Bar (search bar) is the fastest way for users to reach the information they are looking for on your website. If the website is well optimized, Google will show a Search Bar right in your search result, making the website look far more professional and distinctive than other results.

How to set up a Search Bar on a WordPress website

• Go to Admin Dashboard (Dashboard) →  Appearance (Appearance) → Customize (Customize)
• Each theme has its own way of customising this

Where DIY SEO-friendly website design breaks down, and what it costs

A WordPress website installed in one evening is not yet a website ready for SEO. Installation is usually quick; the time goes into planning pages, building content templates, adjusting the interface on phones, configuring redirects, checking the path Googlebot takes and measuring again after publishing. Miss one link in the chain and the website still seems to run fine, but your content team will hit the same errors on every new article.

Budget a full 60 hours first. This is an estimated schedule for someone already comfortable with WordPress, building a company website with 5 to 7 page types, not including photography, writing all the content or connecting custom software. Beginners need extra time to learn; the earlier materials note that getting familiar with in-depth SEO tools can take at least 3 months. So the 60 hours below are for scheduling, not a promise that anyone can finish in exactly 60 hours.

DIY task	Estimated hours	Output required before moving on
Settle goals, keyword groups and the list of page types	6 hours	A sitemap, the purpose of each page and one planned URL for each search need
Set up the server, SSL, a test website and the first backup	4 hours	HTTPS, a separate test environment and a backup you can restore
Build the header, footer, homepage, service pages, categories and article template	16 hours	Shared templates display correctly on both desktop and phone
Set up title, meta, canonical, schema, sitemap and URL rules	10 hours	Each page type outputs the right tags in the source code, not one configuration for everything
Compress images, tune the theme code, cache and test speed	8 hours	Images at the right size, no layout shift, main pages not loading unnecessary resources
Set up Google Analytics 4 and Google Search Console	6 hours	Page views, key events, sitemap and indexing status are recorded
Test forms, menus, 404s, redirects, social sharing and handover	10 hours	A bug log, a person responsible for fixes and a content publishing guide
Total	60 hours	A website ready to move into the content and SEO tracking stage

If a business owner's hour is valued at 150,000 VND, the formula is simple: 60 hours × 150,000 VND = 9,000,000 VND in time. Replace 150,000 with the value of your own hour. Money that never leaves your account is still a cost, because those 60 hours are not spent on selling, handling orders or looking after customers.

How much do the theme, plugins and hosting cost?

The core WordPress software is open source and free to use. A website that goes online still needs hosting, and themes and plugins can be free or paid. To avoid quoting a vague figure, the table below uses a specific paid setup checked on 06/08/2026: GP Premium 59 USD/year, Rank Math PRO 95.88 USD/year and Cloudways hosting from 11 USD/month. Converted at 26,500 VND/USD, rounded from Vietcombank's selling rate of 26,510 VND/USD published on 24/07/2026.

Item you buy yourself	List price checked on 06/08/2026	Converted for the estimate	What the price does not include
Theme GP Premium	59 USD/year	1,563,500 VND/year	Labor to adjust the theme, fonts, colors and page templates
Plugin Rank Math PRO	95.88 USD/year	2,540,820 VND/year	Keyword research, writing content and fixing technical errors
Hosting Cloudways	11 USD/month	3,498,000 VND/year	Domain, domain-based email and server administration labor
Total tool cost in the first year	286,88 USD	7,602,320 VND	Not including the 60 DIY hours

With the sample calculation above, the total first-year resources come to 7,602,320 + 9,000,000 = 16,602,320 VND. This is an estimate for one specific setup, not a MONA quote and not a market average. If you use a free theme or plugin, license costs go down; in return, you have to check the feature scope, update schedule and compatibility yourself, and decide who handles it when two plugins conflict.

A low budget can still work. A small company website with no ads running, no shopping cart, no inventory sync, no multiple languages, and an owner who enjoys learning WordPress is a reasonable case for building it yourself. In this case you can do it yourself; there is no need to hire anyone. Work on a subdomain or test website first, record every change and keep at least one backup you can restore.

Things break when the sales launch deadline is fixed, several people publish content at once, or one change means fixing three other places. A nice theme does not create correct canonicals by itself. An SEO plugin does not know on its own that two service pages are competing for the same keyword. Stronger hosting cannot fix a 4 MB image, render-blocking JavaScript or a mobile menu covering the call button.

8 places DIY builds usually break and how to spot them

1. The sitemap is built after the interface. The sign is that the menu is finished but nobody can say which search need each page targets. Then the URLs, breadcrumbs and internal links have to be fixed backwards from the end to the start.

2. The live website is used to test plugins. One faulty update is enough to stop forms sending or turn the site into a blank page. The way to prevent this is a test website, a backup before every update and a process for rolling back to the previous version.

3. Every page uses the same title and meta. The admin sees no error on the interface, but the source code Google reads is duplicated. Check by opening 10 URLs across 3 page types and comparing the title, description and canonical of each URL.

4. Images are uploaded at camera size. The page still looks fine on Wi-Fi, while customers on 4G wait several seconds. Every image needs the right display size, a suitable format, a compressed file size, width, height and alt text that describes the scene accurately.

5. The phone version was only looked at, never tapped through. The menu opens but the close button sits off screen, the keyboard covers the form's submit button, or tables overflow sideways. Test on at least one iOS device, one Android device and a narrow browser window.

6. Robots.txt, sitemap and canonical are managed by three different plugins. Two places issuing the same instructions easily create conflicting rules. Assign one place to be responsible for each type of data, then check the source code and real URLs after saving.

7. Speed is measured before content is entered. A sample website with three images is usually very fast; once 30 articles and all the real banners go up, the score changes completely. The final acceptance test must run on data close to what will exist on handover day.

8. Nobody takes responsibility after the website goes live. SSL, domain, hosting, theme and plugins all have renewal dates. Without a monthly check schedule, errors only get noticed when forms lose messages, the website expires or Google Search Console sends a warning.

The deciding point is how much failure you can tolerate. If the website is only for testing an idea and a 7-day delay costs no revenue, doing it yourself is the economical choice. If the ad launch, opening day or stock arrival date is already fixed, you need to count the cost of a broken form, a slow page or wrong measurement data, rather than just comparing a theme's price with a design quote.

If the 60-hour table shows that what you are missing is structure, testing or someone to look after the website after handover, see how MONA builds business websites in Ho Chi Minh City. Bring your sitemap and feature list; keep the parts you can do yourself, and only break out the parts that tend to fail for a quote.

The SEO-friendly website design process, step by step from foundation to measurement

The order of work decides how many times things have to be torn down and redone. Locking the interface first and researching structure afterwards often leads to an approved design with no room for categories, expert articles, filters or local content. Doing it right starts with the question of who the website needs to help do what, and only then moves through structure, interface, code, content, measurement and acceptance.

The process below serves as a neutral implementation checklist. Whether you do it yourself, give it to someone in-house or hire an outside company, the same order applies. Every step has an output; no output means no moving on. The acceptance stage opens 10 pages and submits the form twice to collect evidence instead of gut-feel comments.

Stage 1: Settle needs and ownership

1. Write business goals as measurable actions. “Make the website look professional” is not enough to design from. The goal needs to become an action such as submitting a form, calling, booking, viewing the price list, downloading a profile or buying; each action must have a landing page and a way to be recorded.

2. List users and their questions before drawing pages. A shop owner needs to see products, prices, delivery and returns. A B2B client needs capabilities, process, project portfolio and a contact person. A job seeker needs positions, conditions, location and an apply button. Those three groups create three different paths on the same website.

3. Lock ownership in the kickoff minutes. Which account the domain is under, who holds the hosting, who has the highest admin rights, and in what format the source code and database are handed over must be written down before work begins. Leave it late and you can easily end up with a running website whose owner cannot get a copy by themselves.

Stage 2: Build the structure before the decoration

4. Group keywords by need, not by department. One main need gets one main page. Narrower questions become supporting articles that link back to that page. This reduces cases where a service page, a “what is” article and a pricing article all compete for the same search cluster.

5. Draw the sitemap and URL rules. The sitemap needs the homepage, service or product groups, content categories, about page, contact page and legal pages. URLs should be short, readable and not tied to dates if the content needs updating over time. When changing a URL that already gets traffic, make a table of old URLs, new URLs and 301 redirects.

6. Settle one template per page type. Service pages, articles, categories and project profiles do not share one layout. Each template must specify where the H1 sits, how the breadcrumb displays, the main content area, related links, the CTA and which structured data is output.

7. Approve the wireframe on phone before the color version. The wireframe only needs content blocks, buttons and order. Check that the main button appears early, text is easy to read, forms are not too long and tables can be viewed on narrow screens. Fixing things at this step is cheaper than fixing them after the code is written.

Stage 3: Code, set up measurement and load real data

8. Build the code together with the base SEO rules. Configure title, description, canonical, headings, breadcrumb, sitemap, robots.txt, Open Graph and schema for each page type. Each page has only one main H1. Images declare width, height and alt; the theme code must not create hidden content just to stuff keywords.

9. Set up measurement before acceptance day. Google Analytics 4 records behavior on the website; Google Search Console shows which pages Google sees, which keywords generate impressions and which indexing errors need fixing. Setting them up early lets the test session produce real data to compare, instead of waiting until the website is live to find out the form does not record events.

10. Enter content close to the real data. Use long titles, real images, tables, videos, product descriptions and cases with no image. Sample data that is too clean hides text overflow, heavy images, empty categories and layouts that break when content is uneven.

Stage 4: Test and hand over with evidence

11. Test by script, do not approve by feel. Open the homepage on 4G, find a service, submit a form, check the received email, go back to the previous page, use internal search, open a wrong URL to see the 404 page and share a link via social media. Each error records the device, browser, URL, steps to reproduce, screenshot and the person handling it.

12. Hand over with the full set of accounts and a maintenance schedule. The minimum package includes the domain account, hosting, website admin, Google Analytics 4, Google Search Console, the plugin list, renewal dates, a clean backup and restore instructions. The recipient must publish an article, replace an image, edit meta and take a backup themselves before signing off.

Do not swap steps. The interface only starts after the sitemap and content templates are approved. Speed optimization is only finalised after near-real data is loaded. Acceptance only ends when forms, measurement, account access and backup restore all work.

Priority order when budget or time is limited

Priority level	Do first	Reason
P0, required before the website opens	Domain ownership, HTTPS, URL structure, mobile, forms, backups, robots.txt, sitemap, canonical, measurement	Mistakes here lose data, block Google or stop customers from getting in touch
P1, completed in the handover round	Main page speed, suitable schema, article templates, image alt, 404, redirects, admin guide	This is the foundation that lets the content team work steadily without creating new errors
P2, done after usage data is available	Animations, advanced filters, personalisation, multi-variant testing, secondary integrations	Only worth investing in once you know what real users need and which step is blocking conversion

A website without animations can still sell. A website that loses forms, has wrong canonicals or has no backup is at risk right away. So when you have to cut scope, postpone P2 first; do not cut P0 tasks in exchange for a homepage with lots of motion.

A 12-item self-acceptance checklist before taking over the website

1. Open the source code of 10 URLs and confirm the title, description and canonical differ as intended.
2. Check each main page has only one H1 and the H2 sequence reads as a clear, connected flow.
3. Open /robots.txt and the sitemap; confirm pages that need SEO are not blocked and test URLs are not in the sitemap.
4. Use iOS and Android phones to submit the form, tap to call, open the menu, view tables and play videos.
5. Run PageSpeed Insights on the homepage, a service page and an image-heavy article; record the test date.
6. Share three URLs via Facebook or Zalo; check the title, description and preview image are right for each page.
7. Open a wrong URL to check the 404 page offers a way back to the main content.
8. Change a URL on the test website as a trial, check the 301 redirect to the new address and that no redirect chain is created.
9. Submit the form twice and compare the received email, the stored data and the event in Google Analytics 4.
10. Go into Google Search Console to check ownership, the submitted sitemap and that the indexing report is accessible.
11. Make a backup, delete a test item and restore it; record the time and who did it.
12. Publish a new article with the recipient's account, filling in the URL, meta, image alt, category and internal links yourself.

This checklist has 12 lines, pass or fail. Any line not yet done must name the person fixing it and a recheck date, not be replaced with “we'll support it later”. Only when all 12 pieces of evidence are in does the website move on to regular content publishing and rank tracking.

How an SEO-friendly website performs differently from an ordinary one

The difference is not visible on handover day; it shows up after 3-6 months. An ordinary website can look as good as an SEO-friendly one, but Google sees two different worlds: one has a proper heading structure, load speed that meets Core Web Vitals, complete schema data and clean URLs; the other is a nice-looking interface that machines cannot understand is selling anything. The measurable result: on the same content budget, the SEO-friendly website climbs keywords steadily from month 2-3 and holds its rankings, while the ordinary website stays stuck on pages 3-5 no matter how many articles are written, and the owner wrongly concludes “SEO doesn't suit my industry”. Investing in SEO from the design stage is many times cheaper than tearing up the foundation once the website is running: this is why a serious SEO-friendly website design company always puts the technical checklist into the contract from the start instead of selling it as an add-on later.

After handover, can you run SEO yourself?

Yes, and a properly SEO-friendly website should give you that ability. When MONA hands over, you get: an admin panel that lets you publish articles with all the SEO fields (title, description, URL, images with alt), a pre-planned category structure so new articles land in the right topic cluster, an auto-updating sitemap, and a training session for your content team with documentation. On that foundation, a business with someone who writes can run the content side itself; hire a full-service SEO provider only if you want to target highly competitive keyword clusters or need a team to build backlinks properly. A beautiful website that nobody can find does not help anyone. A solid foundation plus a steady publishing habit is the long-term result a professional SEO-friendly website gives you, not a miracle that hits the top in one month.
