4. Linking Root Domains

This is the number of high-quality links your website has generated so far. Thus, if you’ve got 20 inbound links from two different sites, then you’ve got only two linking root domains.

Getting a few backlinks from several sites will increase your search engine ranking more than getting several backlinks from a few websites.

5. Social Signals

When it comes to ascertaining the quality of your content, Moz uses Social Signals as a crucial signal for this.

It’s assumed that you have some high-quality posts when such posts are liked, commented on, and shared dozens of times. And the same Social Signals is leveraged by Moz to evaluate your domain authority score.

6. MozTrust

This particular signal is specifically used to ascertain the quality of inbound links you generate for your website like MozRank.

It also evaluates the quality of the sites that link to your own site as well as the search engine trust of those sites. Generally, it’s believed that search engines trust the .gov or .edu websites more than others.

If a site generates links from such trusted sites, such a site receives an awesome rating by MozTrust. Aside from these, authoritative sites that have domain authority score of 60% and above are also trusted by search engines.
