Facebook Statistics, Stats & Facts for 2011... Did you know 1 in every 13 people on earth uses Facebook?

In addition to that revelation, another piece of critical data came via yesterday’s announcement:
Danny Sullivan: If an article is retweeted or referenced much in Twitter, do you count that as a signal outside of finding any non-nofollowed links that may naturally result from it?
Bing: We do look at the social authority of a user. We look at how many people you follow, how many follow you, and this can add a little weight to a listing in regular search results. It carries much more weight in Bing Social Search, where tweets from more authoritative people will flow to the top when best match relevancy is used.
Google: Yes, we do use it as a signal. It is used as a signal in our organic and news rankings. We also use it to enhance our news universal by marking how many people shared an article.
Danny Sullivan: Do you try to calculate the authority of someone who tweets that might be assigned to their Twitter page. Do you try to “know,” if you will, who they are?
Bing: Yes. We do calculate the authority of someone who tweets. For known public figures or publishers, we do associate them with who they are. (For example, query for Danny Sullivan)
Google: Yes we do compute and use author quality. We don’t know who anyone is in real life
Danny Sullivan: Do you calculate whether a link should carry more weight depending on the person who tweets it?
Google: 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.
We now know that those link sharing activities on Twitter + Facebook are evaluated based on the person/entity sharing them through a score Google calls “Author Authority,” and Bing calls “Social Authority.”
We can probably predict a lot of the signals the search engines care about when it comes to social sharing; some of my guesses include:
- Diversity of Sources – having 50 tweets of a link from one account, like having 50 links from one site, is not nearly as valuable as 50 tweets from 50 unique accounts.
- Timing – sharing that occurs when an RSS feed first publishes a story may be valuable in QDF, but tweets/shares of older pieces could be seen as more indicative of lasting value and interest (rather than just sharing what’s new).
- Surrounding Content – the message(s) accompanying the link may give the engines substantive information about their potential relevance and topic; it could even fill the gap that’s left by the lack of anchor text, particularly on Twitter.
- Engagement Level – the quantity of clicks, retweets, likes, etc. (if/when measurable) could certainly impact how much weight is given to the link.
We can probably also take a stab at some of the signals Google + Bing use for Author/Social Authority in the context of the sharing/tweeting source:
- Quantity of Friends/Followers – like links, it’s likely the case that more is better, though there will likely be caveats; low quality bots and inauthentic accounts are likely to be filtered (and may be much easier to spot than spammy links, due to the challenge they find in getting any “legitimate” friends/followers).
- Importance of Friends/Followers – the friends/followers you have, like the link sources you have, are also probably playing a role. Earn high “authority” followers and you yourself must be a high authority person.
- Analysis of Friends/Followers Ratios – Much like the engines’ analysis of the editorial nature of links, consideration of whether a social user is engaging in following/follower behavior purely out of reciprocity vs. true interest and engagement may be part of authority scoring. If you have 100K followers and follow 99K of them, but the engagement between you and your followers is slim, you’re likely not as authoritative as an account with 100K followers + 5K following, but those followers are constantly engaged, retweeting, liking, sharing, etc.
- Topic Focus / Relevance – The consistency or patterns between your sharing behaviors could also be a consideration, using topic analysis, patterns in the sources of shared/tweeted links, etc. Being an “authority” could even be subject-specific, such that when a prominent SEO tweets links to celebrity news it has less of an impact than when they tweet links to a web marketing resource.
- Association Bias – I suspect Google and Bing do a good job of associating social authors with the sites/domains they’re “part of” vs. independent from. Sometimes, this might be as easy as looking at the URL associated with the account, other times it could be based on patterns like where you most often tweet/share links to or whether your account is listed on pages from that site. Basically, if @randfish tweets links to *.seomoz.org, that probably means less than when I tweet links to bitlynews or when someone outside the company tweets links to SEOmoz.
These signals represent my opinions only, and while it’s very likely that at least some are being used, it’s even more likely that there are many more that aren’t listed above. Over time, hopefully we’ll discover more about the impact of social sharing on web rankings and how we can best combine SEO + social media marketing.
To me, the most exciting part about this is the potential to reduce webspam and return to a more purely editorial model. While people often link to, read and enjoy sources that link out manipulatively, very few of us will be likely to follow a Twitter account, friend someone on Facebook, or “like” something in a social site that’s inauthentic, manipulative or spammy. The social graph isn’t necessarily cleaner, but the complexity of spam is far lower.
Here’s to the evolution of organic marketing – search, social, content, blogs, links – it’s all coming together faster than ever before, and that’s a very good thing for holisticly minded web marketers.Best Link Builder, Best SEO, Top Link Builder
