How JavaScript SEO is Changing the Way Websites Rank

Understanding JavaScript SEO

JavaScript SEO is a process where JavaScript websites are optimised for SEO success, ensuring your site can be crawled, rendered, and indexed effectively and accurately. When you align your JavaScript website with SEO best practices, you can improve your visibility in search results, while boosting user experience (UX).

  • JavaScript is rendered in two phases, meaning it can cause delays and errors
  • JavaScript is versatile and can be used on websites of all sizes
