    Danny, great write up! One question that comes to mind though is, if Google is looking at authoritative users on Twitter as ranking signals, how do they define authority? Is it follower counts? Follower/following ratio? RT counts? Or is it something more old school like the profile pages PagRank?

    And if it is based on friend/follow metric, how are they retrieving that data? Is it done when the initial link is crawled via the web? Or are they scraping the fire hose for link data.

    I find all of this to be very interesting because it seems that this is the first time that a search engine has relied on someone elses data as a ranking signal.

    “Authoritative people on Twitter lend their authority to pages they tweet.” Wow, wow, wow! TwitterRank suspected but great to see it confirmed. Also the importance of RTs from those with authority. I would imagine having an increase in authoritative followers on ones profile would be similar to internal link building, correct?

    awesome! thanks Danny for asking them these questions. Many others reading this probably also felt this was possibly going to be the case, especially those with access to numerous WebmasterTools accounts seeing the dozens of Twitter and FB links showing up in the reports.

    I agree with Joe – how can we really define authority? followers alone are too easy to manipulate. I was thinking number of Lists appearing within, as well as number of “high tweet-rank” people following the profile. great stuff Danny as always!

    Thanks @dannysullivan . And now everyone wants to quantify what a tweet link is really worth! Who wants to start swapping tweet links? … and the spamming begins. =)

    Danny, great to see some disclosure on what’s done and not done by Bing and Google regarding incorporation of social signals. Regarding the question of defining authority, Topsy calculates influence based upon the propensity of an individual to cause others to take action within the social Web. Within Twitter, this is calculated using actions such as retweets, replies & is recursive, so the thread of actions is used beyond just one layer. This means that even if you have a million followers but you’re not causing others to take action on your posts your influence score will be very low. This method also removes spam and noisy content that’s probably not relevant to consumers.
    Topsy calculates influence scores down to the keyword level and uses influence along with relevance match to the search term to rank results, framing them within the timeframe for which that keyword query has a spike in activity.
    For example a search for “social signals” in topsy frames results over the past day because there’s been a spike in posts from this article and ranks results according to influencers & relevance. Check it out http://topsy.com/s?q=social+signals

    @Chris, Followers, RTs, can be manipulated. Seems that it would be similar to a PR score. Analysis who is following RT, how many unique follows, RTs and mentions, and the authority/PR of those connections. You could break it down to a more granular level of original content as well. Throw in a ratio of tweets to RTs, Received mentions to out going mentions. No system will be perfect.

    Quantifying that sure does take the fun out of social.

    Great article write up Danny! Similar to the previous comments, I’m curious to know how they are defining the term ‘authority’. Based on follows/followers? Do they take in consideration of Klout scores, which analyzes a person’s influence on others?

    I also think it would be very easy for someone to create multiple social accounts, like on Twitter, and tweet a link out on multiple accounts, all getting relatively high juice. Do you think that would need more paying attention to?

  • http://daggle.com/ Danny Sullivan

    Joe Hall & Jacksonlo, it’s a combination of things. Google explained some of these when real time search first launched:

    http://searchengineland.com/google-launches-real-time-search-31355

    Since then, both Google and Bing have repeatedly said that in their social/real time products, they look to determine the authority of people based on things like how often they are retweeted and by whom, as well as your overall profile.

    It’s not just having a huge number of followers but important followers, and it’s not just about having a lot of retweets but retweets from people with some authority.

    In other words, create a Twitter account, create 100 more fake accounts that follow it, and that probably won’t boost the authority of that account much — just like having 100 fake accounts retweeting from your main account probably won’t count much. It won’t seem real — it’ll be too much like fake link networks in the “real” world.

    Chiropratic: Yes, I’d agree. I kind of ran out of steam at the end to go into strategy tips from this. But among them:

    + Increase follows to your Twitter account from authorities, which you might do by following them or better, by engaging with them with interesting information, to entice them to follow you. Be interesting. Be helpful. But for goodness sakes, don’t do the Twitter equivalent of a bad link request. “Please follow me” as a reply to someone probably will come across as badly as a “Please link to me” email.

    + Tweet interesting things, and build your account up into a place where people might want to follow and retweet what you put out.

    + Be valued: In the end, treat your Twitter account like you would your web site. With web sites, success with search often comes from having good content, providing value – Twitter can be the same way.

    It’s frustrating reading your questions and their answers because you dance around the issue. Yet, you conclude that they have a “TwitterRank” for individuals, sort of a reputation score. I wish you had just asked this flat out.

    Because I’m not sure that this is true. Bing & Google say search results are “influenced” by who Tweets a message or link, but they didn’t say they actually ranked people or connected individuals with their Twitter profile webpage (which I guess do have a PageRank). That’s what you deduced was happening from their vague responses but I wish you had just asked them this, point blank, to get a “yes” or “no” so this could be confirmed.

    Thank you thank you thank you! While there are not a lot of definitive answers, the questions and responses speak volumes. Twitter and Facebook do matter.

    I am in a constant battle with new small business clients in regards to Twitter and Facebook. So many think these two social networks have nothing to do with SEO and I always argue that they do make a difference in both ranking and traffic.

  • Natasha

    In light of recent articles concerning businesses utilising negative reviews to climb the search results ladder- do you think search engines have (or are developing) any methods to filter out negative tweets/social media responses?

    If I wrote a blog about a terrible online shopping website which included a link to the culprit then I could simply use nofollow.

    But what if I was to instead tweet about my bad experience with aforementioned online shopping website with a link, unaware that I may be helping that business rank higher and gain more customers.

  • http://daggle.com/ Danny Sullivan

    Liz, when I asked something like this:

    “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?”

    That’s me asking if the have a TwitterRank for individuals. To know an individual on Twitter, they have to look at something. The Twitter page represents that person. I suppose I could have said it better — do you have a TwitterRank for accounts on Twitter.

    I was kind of at pains in this story, I thought, to separate out the idea that the page has a PageRank that can transmit authority from the links versus the person tweeting having authority.

    They also did say this. Go back and look at the answers to question 2. Bing says they calculate the authority of someone who tweets. Google says the same. Then both say that links carry more weight based on the authority of people who tweet. Google specifically says “author authority is independent of PageRank.”

    Finally, I sent the entire article to both Google and Bing before I published. I didn’t just write it off the answers I was given. I sent all my conclusions back, so they could review and clarify if I had something wrong. There were a few small changes that I incorporated. After it went live today, I also emailed both to review and send me further comments, if I didn’t have something correct.

    So the conclusions I’m giving you are based on what the search engines have told me and reviewed.

    Natasha, Google said today that it is not using sentiment analysis in search results. See http://searchengineland.com/google-now-using-online-merchant-reviews-as-ranking-signal-57445

    Danny,
    Thank you for spelling this out in an easy to understand way. I think we have all been making guesses at how Bing and Google have been using the social influence sphere to impact their algorithms but this steps us further toward the “known” direction than the “unknown”.
    I think what we will have watch is how this ranks in authority amongst the 200 (or 2000) other factors that go into the algorithm. Will this be a passing phase that is easily gamed or will this progress into a long standing direction of how the information we search for is organized? We are definitely moving that direction but is it a pendulum swing or a released projectile gaining in speed. Time will tell, but thank you for the snapshot!

    Googles attempt to define ‘social signal’ has an extremely high failure risk in my opinion for two simple reasons though plenty of people will believe the promise that more ‘friends and likes’ makes it more valueable than Twitter’s Resonance, it is not.

    Google’s Social Signal Failure Risk #1
    Googles attempt to define social signal has a core premise that social signal supports their SEO business model and that the underlying content on the internet supported by backlinks is sound. This is simply not true as spam rules and you can validate this yourself by asking any brand owner where they rank in a search for their brand. Wikipedia, Amazon and ‘search guru’s’ all work very hard to stand between them and their future customers to extract a toll for letting buyers find their brands.

    Twitter has a much better, cooller and efficient way of understanding ‘social signals’ and value with their simple notion of Resonance that I’ve described on my blogs but is simply like someone tossing a Rubrik cube up in the air and steps back waiting for it to fall. Another person beside them sees a colour pattern that ‘resonates’ or resembles a question or answer important for them NOW and they catch the cube and think about it or spin it around.

    Three things generally happen next., the story on the cube is not what the second person though and they drop the cube to the ground where others can’t see it or they toss the cube into the air either the same way they received it from the other person as a Re-Tweet or toss it up into the air in the form that they find useful and possibly refererence the original Tweeter or not. No spam, no confusion.

    Google’s Social Signal Failure Risk #2
    Let’s assume that Google embraces Twitter’s notion of influential Tweeters and includes their view as a small part of the ‘secret sauce’ or algorithm which determines the web site content offered as part of a response to keywords entered by people looking for answers in their search engine.

    This idea is like taking a glass full of dirty water (spam filled search engine results) and adding some very clean water from a Canadian glacier (Twitter results) and then mixing both and drinking it all up. Not very appetizing or practical.

    I would suggest that corporate marketers and the advertisers that serve them devote a little time to understanding the notion of Resonance which Twitter explains or see examples of SpeedSynch Resonance maps on Twitter @SpeedSynch to understand the difference.

    Good luck with promoting Google’s notion, I hope somebody buys it.

  • http://sebastians-pamphlets.com/ SebastianX

    I’d assume that the PageRank of a Twitter profile is a minor factor when it comes to ranking a Twitter account’s weight / authority. If PageRank plays a role at all.

    Also, I think that meanwhile Google completely ignores outbound link signals gathered from crawling twitter.com. It makes no sense, because they got these data way earlier via Firehose.

    Bing and Google are using something totally different to calculate scores for Twitter users. I bet parsing markup is not a part of the algo. Topsy’s page on influence might provide a first idea: http://corp.topsy.com/about/influence/

    Another thing backlinks are so important to index your site in search engines

  • http://www.ianlockwood.net IanLockwood

    So when links are Tweeted, as the vast majority use URL shorteners, I presume that both search engines are happy to follow these to the actual URL? Would it make any difference if you used a shortener that didn’t 301 to the actual URL?

  • http://mediafunnel.com Steve Chipman

    Danny – was there anything to suggest that the search engines use the Twitter profile Web field to correlate the profile’s authority with a site? Or it it exclusively based on inline URLs? The profile Web field would seem to be a logical and well defined touch point.

    There would also be legitimate, additive authority as in the case when several company principals and or employees have the corporate URL in their profile’s Web field.

  • Brian Robinson

    Hi Danny. Great article. I think what you’re seeing with the different Toolbar PageRanks (TBPR) when logged in vs. logged out is that when you’re logged out you’re seeing the TBPR of the Twitter homepage which is 9 because Twitter adds “#!/” in the URL between “twitter.com/” and “dannysullivan” when you’re logged out and I think Google ignores everything after hash marks (“#”) in URLs since they’re normally just URL fragments or anchors on the same page. You can verify this by viewing Google’s cache of the logged out page and you’ll see that the TBPR is actually that of Twitter’s homepage. When you’re logged in, the URL doesn’t have the hash mark so the toolbar fetches the actual PR of the user’s Twitter homepage which, in your case, is 7.

  • Brian Robinson

    Oops, I think I got it backwards. It’s when you’re logged in that Twitter adds the “#!/” and, therefore, the toolbar shows the PR of Twitter’s homepage.

  • Marketmesuite

    Hi! Great article – this is part of the reason using a tool like MarketMeSuite is so valuable – with the backlink on the tweets you get all that extra SEO juice and brand recognition :)

    Social Networking is being tracked and backlinked like never before for regular users and businesses. Social Scoring with sites like socialscorebureau.com and klout.com is something that is changing this element as well as Google and others paying attention to the quality of the post.
