Communicate on Twitter and Facebook: increase your influence and your engine positioning at the same time …

In an interview with SearchEngineLand, spokespersons for Google and Bing confirmed that engagement on social media, especially Twitter and Facebook, had an impact on positioning in their results pages.

After the PageRank and the TrustRank, we will now have to rely on SocialRank. The SEO community will now have a new hot topic of debate for the next few months.

We know that links from Twitter and Facebook are in no-follow and therefore do not transmit PageRank. However, these links are still considered signals by search engines.

Regarding Twitter, to calculate the weight of these links,SocialRank algorithm will assess the authority of the account according to several criteria (followings, followers, ratio between these two data, listed, retweet and other secret criteria). Each account thus has a score assigned to it, independent of its Pagerank.

On the side of Facebook, Google announces to treat in the same way the links coming from this social network and those coming from Twitter. Bing clarified that it only takes into account links embedded in unprotected posts. While Google calculates the authority of a Facebook account in the same way as a Twitter account, Bing does not calculate authority for this social network.

To conclude, in order to improve its SEO, it is now necessary to obtain links from Influential Twitter and Facebook accounts.

Take care of your customers, Google will give it back…

In parallel to this SocialRank, Google has announced an evolution concerning the negative opinions that can be found on the web. A link can now have a negative impact on the ranking of a site if it comes from a negative context.

Until now, a link had a positive impact, regardless of the context. Smart guys had abused this flaw by deliberately provoking their customers on the web. This is the case of, which had voluntarily refused to cancel an order and insulted a client (more information on this story on the Journal du Net). Following this affair, Google reacted and developed its algorithm. From now on, the feeling of a page is analyzed before calculating the impact of a link. If the sentiment is negative, the link may cause the link site to lose popularity (more info here: Being bad to your customers is bad for business).

So these are two important pieces of information that fall in succession. What do you think ? Are you already integrating social networks and e-reputation into your SEO strategy?
