Change in MozRank of Root Domain from External Links
This alert monitors the normalized (logarithmically-scaled) sum of the MozRank gained from external links on all pages in the paid-level domain of the source URL (Moz Documentation). Changes in MozRank from External Links are generally associated with an increase or decrease in the amount of authority passed to your website from external links.
Increase in MozRank from External Links
An increase in MozRank from External Links to your domain indicates you have received additional links to your website that are passing authority. This is a good indicator that your site is earning valuable links, and will contribute to higher rankings.
Decrease in MozRank from External Links
If the MozRank from External Links for your domain is decreasing, that typically indicates you are losing links. If you see this number dropping, you should check your backlink profile for any recently dropped links, and work to regain those links or replace them. Consistent drops in MozRank from External Sources can be an early indicator of lost rankings.
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 Moz can trigger false positives for this alert if there was a recent index update on their end, which would have an impact on the MozRank of all sites in their index. If you see a big jump or drop, you should check to see if Moz updated their index before freaking out!
