Improtance of Social Media Links in Google and Bing Search Results

Links Shared in Social Media Matter in Search

Search and social go well together, and the search engines are finding more and more ways to use them together. In fact, the right combination's of these two elements could eventually dictate who has the most useful tools for users.
It's become more and more clear over time that having a strong social presence is helpful in building a strong search presence for a variety of reasons, but it's not been so clear, just how the search engines have looked at things like Twitter and Facebook profiles when it comes to organic search ranking.

Search Engine Land Chief Danny Sullivan posted an important article about this very topic, with some rare and surprisingly direct answers from both Google and Bing. While, neither exactly gave away their respective secret sauces, it would appear that they have set some things straight.

Google


Google reportedly uses when an article is retweeted or referenced in Twitter as a signal in organic and news rankings (even though links on Twitter are nofollowed). They also use it to enhance the news universal results (based on how many people share an article).

Google "computes and uses author quality" for when someone tweets. When Sullivan asked if they calculate whether a link should carry more weight depending on who tweets it, Google Responded, "Yes we do use this as a signal, especially in the 'Top links' section [of Google Realtime Search]. Author authority is independent of PageRank, but it is currently only used in limited situations in ordinary web search."

Google says it treats links shared on Facebook Fan pages the same way as tweeted links, but they have no personal Facebook wall data. Authority for Facebook Pages is also treated like Twitter.

So, the more authoritative the crowd sharing links to your content, the better. Not that different than PageRank.
Bing

When it comes to Twitter, Bing tells Sullivan it also looks at social authority of users and more specifically, looks at how many people they follow and how many follow them, adding that this can add "a little weight" to a listing in regular search results (though it carries more in Bing's separate Social Search). Bing decides when links should carry more weight based on the person who tweets it.

As far as Facebook, Bing currently looks at links shared on Facebook that are marked as being shared to "everyone" and those from Fan Pages. "We can tell if something is of quality on Facbook by leveraging Twitter," as Sullivan paraphrases Bing's response. "If the same link is shared in both places, it’s more likely to be legitimate."

Bing does not use its new Facebook data in ordinary web search...yet.
