Change in Domain Rating
This alert is based on the Domain Rating, which exists as a comparison of your site’s rankings to the rankings scale of all other website domains across the world. Changes in Ahrefs Rank are generally associated with a shift in the link popularity score for a domain, and is often compared with Google’s PageRank scoring. This metric compares the authority of your domain with all other websites indexed by Ahrefs.
Increase in Domain Rating
An increase in your Domain Rating indicates an increase in overall ranking authority for your website. This is a good indicator that your site has more relevant content, and is increasing the number of inbound links (external and internal) contributing to the overall authority of your website.
Decrease in Domain Rating
If the Domain rating is decreasing, that typically indicates you have less relevant content on the site and are losing links and/or authority for your website. If you see this number dropping, you should pay close attention to ensure that you have not noindexed authority pages of your site, or recently lost a number of authoritative links.
Let’s hope you have recently garnered new authoritative links to your site and you see this number 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!
