FATREL is a free extension that adds a checker to your browser. It checks the URL you are on for links with tags, rel=nofollow, rel=sponsored, or rel=ugc, which indicates that the link was paid for.

This extension works with Google’s announcement. It works for all recently supported rel tags announced by Google. This means that it covers the nofollow, sponsored, and ugc tags.

FATREL was developed for user experience and ease of use. It will show you quickly and accurately what relationship tags are on a website with colour coding while letting you toggle between them and choose the one you want the extension to show.
