A guide to configuring SEO in NextJS

NextJS stands out thanks to Server-Side Rendering (SSR) and Static Site Generation (SSG), two foundations that help Google crawl the site better. So if you want to do NextJS SEO the right way and improve search rankings, you need to master the standard SEO configuration steps below:

Optimize meta tags in NextJS 

Meta tags are the basic part of NextJS SEO configuration, because search engines need the title, description and Open Graph to understand the page. You can add these tags through Next/Head and customize them for each page or post.

Example: When you create a guide page SEO website in NextJS, instead of leaving the defaults, you can customize these tags professionally, like this:

Apply SSR and SSG strategies for NextJS SEO

One reason NextJS helps with website SEO is its ability to combine SSR and SSG.

SSR renders content on the server before sending it to the user, which makes it easy for Googlebot to collect data. SSG, on the other hand, creates static pages that load very fast, which suits websites with content that rarely changes, such as an about page website SEO services or a blog category.

You can look at the NextJS getStaticProps function (for SSG) below for a clearer overview:

Add a sitemap and robots.txt file to your website 

The sitemap and robots.txt file are the foundation of any website, not just NextJS SEO. Specifically:

• Sitemap: Lists all the important URLs on the website, helping Googlebot understand the site structure and find all the content you want indexed. To streamline this, SEO specialists should create a sitemap file in the app folder or use the next-sitemap package to generate it automatically.
• Robots.txt: Tells Googlebot which folders it should and should not crawl. For example, you can disallow admin pages that don't need SEO.

Optimize page load speed for NextJS SEO 

You can optimize page load speed in NextJS by using built-in features to improve user experience and SEO:

• Image Optimization: Optimize images with “next/image” to reduce size and speed up loading.
• Lazy loading: Load only the images that appear on the screen.
• Code Splitting: Load only the parts of the source code that are needed.

On large websites, if SEO specialists has to work on each page one by one, it takes a lot of time. That is why NextJS lets you combine Layout and generateMetadata (from NextJS 13) to manage SEO and dynamic routes more flexibly.
