Bing is now using Facebook data to display websites your friends have “liked”. This is influencing the ranking of the search engine listing results in a way that is personal to you and will display results on the first page which could previously have been several pages deeper.
If you don’t want to see results liked by your friends, you can avoid using this feature by simply not signing into Facebook. But I suspect the people you want to reach will be using it.
I was thinking a long time ago that if I owned Facebook, I would develop a search engine to correlate search results with sites that friends like. Although this is not something that I would like in a search engine that I use, I think this is good for Facebook and a good search engine niche.
Google has also transitioned from a really good search engine that I liked using to a yellow page type site with local listings that I don’t like. When I want local search results, I go to a yellow page site. With the Google and Bing transitions from a traditional search engine, this leaves the door wide open for a new search engine to take Google’s original place.
With Google and now Bing moving away from traditional search results, this will have a significant impact on search engine optimization aimed at appearing in the top natural search results and will spawn a new direction in search engine optimization.
