Open Graph protocol

The Open Graph protocol enables developers to integrate their pages into the social graph. These pages gain the functionality of other graph objects including profile links and stream updates for connected users.[24]The implications that the Open Graph may have on the web as a whole relate significantly to the idea of search engines. While currently Google still attracts more traffic than any other website, Facebook is a close second.[25] Even without a good internal search engine, Facebook already drives more traffic for some searches, specifically social searches, than Google itself.[26] And in attempting to link Facebook with the rest of the web, the Open Graph is creating Facebook’s own extensive and highly interactive version of a search engine. It is important to note, however, that Google still holds significant importance in the large scheme of things, and even if Facebook does surpass Google, Google will likely continue to warrant enough traffic to play a large role in the online world.
