Authority Metrics

The LRT™ Trust metrics and the SEOmoz authority metrics specify the probability of a page or of a domain with ranking authority in Google.

Trust
Indicates the implicit trust of the page in the Google search results – works similar to the system of the Trust Rank Patent.
Trust dom
Indicates the implicit trust of the domain.
Trust topdom
Indicates the implicit trust of the top-level domain.
MozAuthPage
Moz Page Authority.
MozAuthDom
Moz Domain Authority.

The more trusted a page/ domain/ top-level domain is, the better. In any case, try to get links from highly trusted sites, because the Trust will be inherited.
