This alert is based on the number of nofollow links found pointing to your paid level domain. This can be affect your Ahrefs Rank (Your site’s Domain Rank), which exists as a comparison of your site’s rankings to the rankings scale of all other website domains across the world. Changes in the nofollow attribute are generally associated with a negative shift in the link popularity score for a domain, and is often compared with Google’s PageRank scoring.

Let’s hope you have recently improved the relevance to your site, and webmasters are changing the link attributes from nofollow to followed link on a steady upward trend. It is important to note that Ahrefs can trigger false positives for this alert if there was a recent index update on their end, which would have an impact on the Ahrefs Rank of all sites in their index. If you see a big jump or drop, you should check to see if Ahref updated their index before freaking out!
