Head of Google's webspam team, Matt Cutts has confirmed how important Google Author verification is becoming. In the latest video, Cutts said that verification will make the content you generate yourself more valuable. The links in the content will become more valuable and it will replace the old fashioned link building techniques.
Here's the question asked in the video: Will Google be evaluating the use of rel="author" moving forward as more sites use the feature on generic, non-article/news pages, such as the home page or an about page?
Cutts is pretty excited about the rel="author". He said that if you can move from anonymous web to a web where you have some notion of identity and reputation of individual authors, you can get lot of benefits for free. It's a hurdle for spammers to hide over here or in some anonymous corner. Though Matt continues to support anonymous speech but at the same time if any verified author writes something on the forum, even if the forum doesn't have that much Page Rank, Cutts would like to know about that.
He further told that Google has been moving from keywords to strings towards things. So, it has the knowledge graph. Google has started learning about real world entities and real world real relationships between entities. In the same way, if you know who the real world people are who are writing the content that could be really helpful and might result in improving search quality.
This is what Matt is personally interested in and several people in search quality group continue to work on. Google will continue to look at it as far as seeing how to use to rel=author to improve search experience.Matt Cutts on the Use of rel="author" and Google Taking it Forward!,
