SEO is crucial if you are utilizing a Single Page Application (SPA) for a website that is not behind a login. JavaScript is increasingly being used to create websites. Presenting your material is crucial since Page Ranking considers more than just relevancy and quality. It also considers how quickly the user can view the information. Even if Google suggests using the built-in capacity for interpreting JavaScript applications, JavaScript prerender is still necessary.
What is prerendering? Pre-rendering is a web browser function that expedites online browsing. When you visit a site, content from another web page or site may be prerendered in anticipation of your visiting it later. If you do, many of the new page's elements have already been rendered, so it loads quite rapidly.
How can you tell if your page is prerendered? Examining the HTTP response headers of the request is the simplest technique to determine whether a page has been prerendered. The page is prerendered if the header is X-HS-Prerendered. The alternative way to tell is to load the page with the query parameter ?hsDebugOnly=true. It will also state whether or not the page can be prerendered. If prerendering is not possible, it will list problems that prevent prerendering.
