This is a very important and also highly exciting move on the part of Google; highly exciting for anyone who just loves to be connected to social network sites and who truly knows the value of the social network’s advertising power through word of “social mouth.”
As of now, you will start to see Google SERP Listings that have actually been picked up from a number of social network sites, particularly Twitter which seems to be getting a lot more Google air time in comparison with the other social network sites.
Google had already started to list text elements and images/videos that had already been posted on social network sites. However, these listings had always been written by the person who posted the information. Posts, images and videos that had been reposted and shared by people other than the author on social network sites have not yet been listed on the SERP by Google.
