To use Prerender, you must have an integration that redirects bot requests to our service. If a request is forwarded to Prerender, it will try to fetch the page and render it.
There are two main methods to avoid rendering certain URLs.
You can avoid the rendering of unwanted URLs by modifying your integration to prevent specific URLs from being redirected to Prerender. This way, the search bots will still be able to index the pages, as your server will be able to serve the URLs to them.
The viability and exact implementation depend on how your integration is implemented and also on the nature of the unwanted URLs.
Alternatively, use the Cache Manager menu to add an Ignore URL filter for unwanted URLs, causing Prerender to return a 404 status code for those pages in this case, these pages will not be indexed by bots.
