There are three Moz Rank factors

External Moz Rank

Moz rank uses link juice by analyzing the in bound links, in external Moz Rank only the links coming from external domains. If your content is good the people will like to link to your pages, this tells Moz Rank that your content is important and will increase the Moz rank, which in turn have an effect on Domain Authority.

Domain Level Mozrank

This also uses Moz rank but on the Domain Level, in this moz compare one domain importance with other. Moz uses an algorithm to analyze the importance of domain, Domain level moz rank is computed for both root domain and subdomains. This will help Moz rank by checking the domain Authority of the domains from which the link is coming from.

Moz Rank Passed

This is a way to analyze the power of links coming to a domain, This will take the note that how many more links are there on the page that is linking to your website. Number of links and domain authority of the page linking to your website helps moz rank to establish a rank.

Moz Trust

Moz trust also uses links to determine the trust flowing to your website. Moz have some trusted website which you can consider a source for trust, these websites are government websites (.gov), educational websites (.edu), or website with large number of content which is useful like Wikipedia.mozTrust-domian-authority

Moz trust measures that how far you are from the trusted source. For example if a .gov site links to you directly then you have a major trust flowing to your website with a single link, and if the same .gov website links to a website named A and then this website named “A” links to your website then again trust will flow to your website but it will be less than the direct link, so if there are more websites in between then the trust factor keeps on getting decreased.

The power of trust flowing to your website also gets effected by the fact the link you are getting form is the home page or not. Home page is the most important page of the website, so if you are getting a link from a home page then the trust flowing from it will be greater.

Moz trust have an algorithm which takes note that from which page the link is places and how far the trusted source is.

Moz trust is also related from 0 – 10 where 0 being the least trust and 10 being most, its easy to have a trust of 3 – 4, when it comes to have a trust of 8 – 9 it is more difficult to have that.
