This year, Matt Cutts is back with this newest video on Google Webmaster Help – Youtube Channel explaining the ranking values and importance of links gained from Twitter, Facebook and other social networking sites. Here he explained that there is a possibility that link juice may pass from Facebook if your account on FB is set as public – which mean if it can be crawled by Google without any password restrictions. However, if asked if FB and Twitter has a high ranking value effect on your organic search, Matt said that they treat every source of links the same regardless of platform or domain.
Google give more importance on reputable links rather than the quantity of the said links.
Here is the video of the said discussion:
Actually, I know that Twitter and Facebook can’t give any value to the organic ranking of the site. However, even its backlinks generated for your site is nofollow (link juice is not pass), it can still be a good source of traffic. Imagine, Twitter is top 12 in terms of traffic while Facebook is known to be on number 2. Aside from that, I am seeing a lot of Twits lately from the real time search results of Google which brings some traffic for some of my sites.
