TrustRank is an algorithm that is used to identify sites on the web that aren’t spam and filter them out. This algorithm helps search engines distinguish between quality and reputable sites from spammy sites using link analysis.

 TrustRank was developed in 2004 by Stanford University and Yahoo! researchers. It analyzes some trusted seed sites and their outgoing links.

How TrustRank Works

• The algorithm begins with a collection of trusted websites that have been manually analyzed.
• The closer the link source to the TrustRank Sites the higher the TrustRank.
