Compare the JS vs non-JS version of the page by all parameters important for SEO with JetOctopus in a very simple way.
1. Go to the “Tools” menu and select the “Compare JS vs non-JS” menu.
2. Next, enter the desired URL in the special field (1) and select a user agent (2). Since many sites use dynamic rendering for Googlebot, we added Googlebot Smartphone (Mobile) and Googlebot Desktop to the list of user agents, in addition to mobile and desktop browsers. You can also activate the “Clean <script> tags after render” checkbox to remove all <script> tags from the DOM after execution (3).
3. In the results, we highlighted the most important elements for SEO: comparison of content, meta description, H1 heading, indexing rules, canonical, status code, and others.
Below you will find the code of each version and you can open each version in the browser and see how Googlebot views your pages.
For example, if there is noindex,nofollow in the raw code, and if the correct meta robots with index,follow are rendered by the client browser, the search robot will accept the page as non-indexable, even after rendering.
