The leaked google review guidelines stressed that human reviewers should examine the EAT factors of a site: Expertise, Authoritativeness, and Trustworthiness.
It gave specific methods to the HUMAN raters on how to do this, such as checking review sites, doing google searches on the author, etc.
But how does the ALGORITHM measure these factors?
Does the algorithm actually take into account reviews from third party sites? Does it try to parse whether the wikipedia entry for that author / entity is "positive" or negative?
While SEO's seem to have joined the EAT Bandwagon, none of them seem to have given a clear definition of what the ALGORITHM would use to determine EAT.
Is negative reputation the new negative SEO?
