Similar link is a feature on search engine results pages (SERPs). It’s used to create another SERP that lists webpages which are similar to a particular website that has been searched for. In this way, users are able to refine their searches and focus in on the types of websites and webpages that they are searching for.
To access the similar link feature, a user must click on the green down arrow which is underneath the webpage hyperlink and next to the page’s URL, and click on “Similar” from the drop-down menu that is revealed.
