At a time when social rank is increasingly on the rise, webmasters tend to forget about trust rank, another “off-site” criterion that Google put in place a few years ago. Social Rank is a classification criterion that takes into account social signs to order research results. Some website managers focus so much on this one that they sometimes forget the others, and the Trust rank can make a difference.
In fact it is the ranking of web pages of the search engine based on the number of links that come from trusted sites and evaluated by human experts. It is a method derived from the pagerank that has been set up to avoid positioning fraud: often obtained by overdriving incoming links of poor quality.
The authority of the domains: A study of a recent very relevant case makes it possible to observe that Google takes into account the alt of the images which make the links as the anchors of classic texts. More importantly, it also seems that Google continues to apply its trust rank policy that analyzes the authority and legitimacy of the site that issues the link in order to verify its credibility as a website. One observation that goes in the direction of the last updates of the search engine (Penguin) which depreciate the anchors text optimized.
