The Eyeflow blog has a post with Phil Laboon’s presentation notes on how search has changed over the past eight years. This presentation was during our November 2009 seminar.

“One trend that I think we are going to hear a lot about next year is how search engines are going to depend more on User Reviews from various community sites like Yelp, e-pinion, and their own locals. In the past, the great hurdle was spammers creating hundreds of bogus accounts and hyping up their own companies.”
