Google publishes documentation on dynamic rendering for crawling, indexing, and manage high- intensity JavaScript based WebPages that is having issues in Google. Till now, not all search crawlers are able to process JavaScript successfully. So, to fix this problem for a while Google recommend Dynamic rendering as a workaround solution to this problem.

Not all sites need to use dynamic rendering:

Google made this very clear that is it not for everyone but pages where content that uses JavaScript features or content that changes rapidly are not supported by crawlers are need to care about.

Dynamic Rendering:

Google defined it as “switching between client-side rendered and pre-rendered content for specific user agents”. And they also explained that it requires your web server to detect crawlers (for example, by checking the user agent) and get requests from crawlers that routed to a renderer whereas requests from users are served normally. When and where needed, the dynamic renderer serves a version of the content that’s suitable to the crawler, for example, it may serve a static HTML version. You can decide to enable the dynamic renderer for all pages or on a per-page basis.

Follow these 3 steps to make dynamic rendering works on your web server:

Step 1: Implement

I. Install and configure.
II. Choose the user agents.
III. Get verifying request from legitimate crawlers.
IV. Determine require content for desktop or laptop.
V. Configure your server to deliver the static HTML.

Step 2: Verify by checking a URL

I. Mobile-friendly test.
II. Test your desktop content.
III. Structured Data Testing Tool.

Step 3: Troubleshooting


By following the above steps you can implement dynamic rendering if your site is using a lot of heavy JavaScript and having a hard time crawling, indexing those pages. Otherwise, it is good for SEO and webmasters to brush up on this.
