If you append your content page URLs with multiple parameters or dynamic parameters it can impact the rendering of Related search for Auto ads on your pages. If you think this might be the reason why you're not seeing Related search for Auto ads on your pages, follow the guidance below.
Before related search terms can appear on your site, Google first needs to crawl your pages to generate suggested terms that are contextually relevant. Until a page has been crawled, we're unable to show related search terms on that page.
URLs containing query parameters such as tracking variables, user IDs, session IDs or other dynamic identifiers can interfere with the crawler's ability to assess a page's core content. This can lead to inaccurate or irrelevant related search terms.
Dynamic identifiers in particular can make it difficult or even impossible for Google to determine if a page has been crawled. When we're unable to make such a determination, related search terms can't be shown. This means that you miss an opportunity to engage with users and monetise your site with Related search for Auto ads.
To maximise the benefit of Related search for Auto ads on your pages, we encourage you to avoid the use of dynamic or excessive URL parameters that do not materially affect the page's content, appearance or functionality. Related search for Auto ads performs best when a content page has a consistent URL with each visit.
