Google + Bing Confirm that Twitter/Facebook Influence SEO

Posted: 02 Dec 2010 02:02 AM PST

As of yesterday, both Bing and Google have confirmed (via an excellent interview by Danny Sullivan) that links shared through Twitter and Facebook have a direct impact on rankings (in addition to the positive second-order effects they may have on the link graph). This has long been suspected by SEOs (in fact, many of us posited it was happening as of November of last year following Google + Bing's announcements of partnerships with Twitter), but getting this official confirmation is a substantive step forward.

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?

Bing: Yes.

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.

Top 10 Must Have SEO Extensions for Google Chrome

Posted: 01 Dec 2010 11:58 PM PST

Posted by pmahler

This post was originally in YOUmoz, and was promoted to the main blog because it provides great value and interest to our community. The author's views are entirely his or her own and may not reflect the views of SEOmoz, Inc.

Every few years I make a browser switch and my web use evolves sometimes for the better, and sometimes for the worse. My particular evolution went something like this: Netscape, IE, KDE Konquerer (switched from Windows98 to Debian - so no more IE), Mozilla Phoenix (early Firefox), IE (what do you know... went back to Windows), Firefox, IE, Firefox, and over the last year Chrome. My latest switch to Google Chrome has had the biggest affect on my daily web usage, particularly from the amazing assortment of extensions. The browser is also light and stylish with cool themes. If you haven't tried it already I highly recommend you do. With Chrome quickly gobbling up market share, it's clear I'm not the only one who's recognizing this.

Ok, enough of this Google fanboy madness... let's talk about some SEO tools. Google Chrome's Extensions, much like Android's Apps, are full of garbage with a few gold nuggets hidden amidst the madness.

1. MozBar

Yes, this is SEOmoz, so you might expect this to be top of the list. However, SEOmoz has done an exceptional job with this tool. Before becoming a Pro Member I used it daily and now that I'm a pro member it's always on it. Note: I'm not just saying this to get my blog post boosted to the main blog (wink wink), but it really is the best tool out there and an essential for tool any aspiring SEO.

2. SEO Site Tools

SEO Site Tools is an all inclusive powerhouse of SEO information. It includes 6 main sections:

External Page Data
Page Elements
Social Media
Page Terms / Tools
Server / Domain Info
Suggestions

Some of the unique features and enhancements include highlighting your domains in Google search, trend data in Google webmaster tools, and Social Media stats in Google Analytics. A close second to MOZbar, this tool is an absolute must.

3. Note AnyWhere

I don't know if I'm the first to break news of this tool. But even if you hate Chrome, this tool makes it all worth it. It's basic, it's simple, but it has already completely changed the way I work. As the name says you can leave a note... that's right, anywhere. On any page, on any site... leave... close your browser and come back 2 days later. I just left a note on my home page with new keywords I want to target and a note on my Fantasy Football page with all the players I need to drop (sorry Randy Moss).

4. Firebug

Get down and dirty with your code or your competitors code. You'll be able to find the tweaks and tags that can boost your rankings. Not for the beginner but an absolute must for the OCD expert.

5. IE Tab

Another holdover from Firefox, IE Tab allows you to browse the web as if you were using IE. I use this extension at least twice a day to confirm page appearance, double check a ranking, or if Chrome is having an issue with loading a page.

6. SEO SERP

I've found this tool to be slightly buggy. However, the usefulness is there and I'm sure they'll iron out the issues soon. Basically what it does is it allows you to check your search rankings per term. Quick and simple, definitely saves time for those of us that occasionally get addicted to checking rank.

7. Goo.gl URL Shortener

Shorten URLs on the fly, add them to history, integrate with social media... do I really need to explain this further? It's a time saver.

8. Screen Capture (by Google)

No more CTRL+ALT+PRTSCN, this simple tool by Google let's you highlight the section of the page you want, highlight the visible area, or highlight the whole page (can't do that with PRTSCN - that I know of). After you select, annotate, highlight, mark it up however you'd like and then email it to that lazy coworker who can't find the broken link or misspelled keyword. It's like slapping them... nicely.

9. Google Reader

Let's face it, there's a lot of information out there for SEO, it's a highly dynamic industry and you need to be on top of your game to stay in it. Google reader is the essential tool

10. Stay Focused

Ever spend 3 hours trying to figure out which who to trade Randy Moss for on Fantasy Football? Nah, me neither... this little tool will help with all that though. Get back to your link building, get back to your analytics, and StayFocused. OK, honesty time... I ended up disabling this tool... but you shouldn't, it's awesome and works better than you think it will.

Well as I'm sure you know by now there's a ton of tools out there, and while Chrome and its extensions are just one of them, I think they're worth a try... and no... I don't work for Google. I'd love to hear your recommendations as well.
