Search engines commonly build trust by approving identity on a tracked website.
Search engines have explored various ways to help verify web sites as well as authors that are writing for them. Perhaps the most dramatic attempt was Google Authorship. While Google ended Google Authorship in 2014, the search engine still tries to assess authorship for use with Author Rank in other ways.
Identity and authorship systems will likely continue to evolve, so it is best to keep apprised of new services for identity verification.
The current methods for maximizing verification include:
- Klout for Bing,
- Verifying websites with Bing Webmaster Tools and Google Search Console,
- Linking your site to Google+.
