Google AdSense has introduced a new feature called related search for Auto ads. This feature displays search terms that are relevant to the content on the pages users are viewing. If a user clicks on one of the suggested search terms, they will be directed to a search results page where they can engage with AdSense for Search ads and relevant results from the website. This feature improves targeting precision for advertisers and enhances the overall user experience. The related search feature can be activated in the Auto ads settings page and does not count towards the ad load on the page. All publishers now have access to this feature. More information can be found in Google AdSense’s Auto Ad guide.
