Visibility

This metric in Ahrefs’ Rank Tracker shows what percentage of all clicks for the tracked keywords land on your website.

For example, let’s say you track one keyword, and all the top positions in Google are occupied by pages on your website. Because your website gets all possible traffic from that keyword, your Visibility is 100%.

Now let’s say your website only occupies one spot in Google, with the rest occupied by competitors. Because some clicks go to other websites, your Visibility is lower than 100%. 

If your Visibility is increasing, this is yet another good sign your SEO is on the right track.
