What is CRO?

CRO (Conversion Rate Optimization) is the process of optimizing your conversion rate, turning website visits into leads and, in the end, into real customers for your business. To run CRO in marketing, you need to understand user behavior on your site, the actions they take, and what makes them care about and engage with your product or service.

  • Micro conversions: These are small but important conversion steps that show how customers engage with your website. For example: a visitor signs up for the newsletter, downloads a document or follows the business on social media. 
  • Macro conversions: Only the key conversions that happen on the website. For example: a customer completes a purchase, signs up for a service or fills in a contact form.

How are SEO and CRO related?

SEO and CRO are symbiotic and support each other to deliver the best business results. Specifically, SEO sits at the top of the sales funnel, with the main job of bringing quality traffic to the website. Once traffic arrives, CRO takes over at the bottom of the funnel, making sure part of those visitors turn into real customers.

How SEO and CRO are related

So the higher the quality of visitors SEO brings in, the easier it is to improve the conversion rate, and the simpler CRO work becomes. Running a CRO in marketing strategy on your website also has a positive effect on SEO Google. Factors such as page speed, site structure, images and content not only improve user experience but are also signals Google rewards, which improves search rankings.

  • Build quality content: It earns Google's trust in your website and gives users real value, which raises the chance of conversion.
  • Optimizing elements SEO Technical: Page speed, a mobile-friendly website and an SEO-friendly structure all support user experience and lift search rankings.
  • A clear, intuitive site structure: It helps Google index your site and helps users find information easily, which makes them more likely to act on the website.

What are the benefits of optimizing website CRO?

Focusing on conversion rate optimization brings strategic benefits that directly affect your business's sustainable growth. So what exactly are the benefits of optimizing CRO?

Improve the customer experience

Khi Conversion Rate goes up, it means customers are engaging more positively with your brand, which shows they are happy and trust you enough to spend time or money on your site.

Improvements such as readable fonts, an intuitive layout and clear, prominent CTA buttons make it easier for customers to interact. When customers enjoy the experience on your website, they not only stay longer but tend to come back, and become loyal customers.

Stronger brand awareness through CRO

They remember your business when they need a related product or service and easily share a good experience with friends and family. As a result, organic traffic and leads grow, which builds brand reputation. 

Better brand awareness

How to calculate CRO conversion rate, explained for SEOers 

By mastering how to calculate conversion rate, SEO specialists you can measure traffic performance accurately and steer your CRO strategy better. Depending on your business goal and the nature of your website, you can use one of two methods:

Conversion per website visit (session)

For e-commerce websites (where a user can buy several times in one visit), you need to measure conversion by sessions.

Say a user visits your website 3 times, so you get 3 chances to convert:

  • Session 1: The user is just starting to look around and leaves without converting.
  • Session 2: The user comes back and buys one product. This counts as one conversion.
  • Session 3: The user buys two more items. Although the number of products goes up, the system records only one order, which is one conversion.

Formula for conversion rate by session:

Conversion rate = Unique orders / Total sessions

This method suits CRO models in marketing with a high purchase frequency, helping you measure buying behavior per visit accurately and optimize the conversion rate better.

How to calculate conversion per website visit

Conversion per unique visitor

On some kinds of websites, such as course-selling sites or robot installation services, a user may visit many sessions, but once they sign up and buy, they will not convert again.

Example:

  • Session 1: The user visits the website to read information but has not signed up.
  • Session 2: The user signs up for the service, and this is the only conversion.
  • Session 3: They come back to read the blog or look at more documents without producing any further conversion.

In this case, counting conversion by sessions is not accurate. Instead, you SEO specialists need to look at the number of unique users.

Formula for conversion rate by user:

Conversion rate = Unique orders / Total unique users

How to optimize your website conversion rate

To optimize your CRO conversion rate successfully, you need a systematic process based on real data instead of gut feeling. Below are the strategic steps MONA has used to improve website performance for hundreds of businesses:

Set up user behavior tracking

You cannot optimize CRO without data, so set up your measurement system from the start:

  • Settings Google Analytics 4 (GA4) to track user behavior by page and by action.
  • Connect Google Search Console to review search performance, keywords and devices.
  • Use Google Tag Manager (GTM) to set up custom events such as button clicks, video views and scrolling…
  • Integrate Microsoft Clarity to collect heatmaps and session replays, so you can watch real user behavior directly.
Track user behavior with GSC

Analyze and review website UX/UI

Once you have data, the next CRO step in marketing is to analyze behavior and see where users struggle. Look at heatmaps to find where attention concentrates, which areas get ignored and where users often misclick.

Combined with watching behavior recordings, you can spot the key drop-off points and the reasons users do not finish a task. Finally, review the experience on desktop, mobile and tablet to make sure the interface stays consistent and easy to use.

Optimize the interface, layout and navigation

Based on the UX/UI analysis, you should make changes that improve the conversion environment. Specifically:

  • Adjust colors, fonts and layout for clarity and an intuitive feel.
  • Reposition CTAs, contact forms or images to reduce distraction.
  • Shorten the path from viewing a page to taking the conversion action.
  • Optimize internal links to guide users to key pages and lower the bounce rate.

Optimize high-converting pages

Pages that decide revenue (such as product pages, landing pages and form pages) should get the strongest conversion rate optimization first. Focus on these points:

  • Refresh content, images and bullet points to be more convincing.
  • Improve page speed by optimizing images, code or hosting.
  • Shorten sign-up forms and add trust elements such as reviews and clear policies.
  • Upgrade CTAs so the message is clear, prominent and easy to click.

Set up A/B testing

In CRO marketing, A/B testing helps you decide from data instead of gut feeling. Create two versions of an interface or CTA and measure metrics such as click rate, time on page and conversion rate. From the results, pick the best option and keep testing more variations.
