Dynamic rendering preset JavaScript in a different way.

In dynamic rendering, the webmaster sends the full version of the site page to the search engine but displays the regular site to website visitors.

In this way, Google crawlers visit your page and index it without using JavaScript.

If you want to minimize crawl time and budget, then you should consider using dynamic rendering.

Before using dynamic rendering on your website, here you should know how dynamic rendering works.

How Dynamic Rendering Works?

Dynamic rendering is not as simple as HTML. Installing dynamic rendering on your website can be time-consuming, challenging, and intensive.

The typical dynamic rendering work is to serve users with JavaScript experience but send HTML files only to search crawlers.

Here is what you should understand:

  • Install dynamic renderer to identify search engine crawlers.
  • Dynamic rendering understands the crawlers and presents content that is easy to index for search engines without JavaScript.
  • Dynamic rendering displays the page with the whole HTML and JavaScript experience for a user.
  • Dynamic Rendering Solve Problems:
  • Dynamic rendering makes it easy for search bots like Google crawlers to index your website content quickly.

It saves load time for search engines and makes it easy for your website to get indexed in SERP.

Search engines will crawl your website without taking the JavaScript process. In other words, your site without JavaScript features will upload in the search index.

You should consider dynamic rendering if you are using a massive website like ecommerce or news website.
Improving your site indexing will help in SEO and content marketing.

Should You Use Dynamic Rendering or not?

If you have many JavaScripts on your website, then it is wise to use dynamic rendering. But it is a short-term solution.

Dynamic rendering also reduces your crawl budget. It is a quick way to index your website pages and save resources.

When should you consider using dynamic rendering?

  • Large websites
  • Site with Updated JavaScript functions.
  • Sites with chat apps and massive social media sharing.

Dynamic rendering vs. Cloaking:

Cloaking is a black hat strategy where a webmaster creates a website that sends two different content versions of one page.

The sole purpose of Cloaking is to mislead search engines to chase ranking.

Dynamic rendering is different than Cloaking.

The site sends the same content to users and search engines in dynamic rendering.

But search engines will get site content without JavaScript to index quickly.

How to use Dynamic rendering?

If you have a JavaScript-heavy website, use dynamic rendering to make indexing fast.

Search engine crawlers find it difficult to crawl sites with too many JavaScripts. They prefer sites with less or no JavaScript.

You should understand that dynamic rendering needs additional resources and can slow down your hosting server speed.

Dynamic rendering serves users with site pages rendered with JavaScript and serves search engine bots with site pages without JavaScript.


Dynamic rendering helps solve JavaScript SEO issues.

But it is a short-term solution that can slow down your site.

Before using dynamic rendering, you should know the following:

  • Website is indexable or not.
  • Is the site using JavaScript or not?
  • Does your site have dynamic content?
  • Sites with crawl budget issues.

Due to JavaScript issues, dynamic rendering will help index pages, not indexing. It is the easiest way to make your website crawlable and indexable.
