Twitter Data

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?

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?

Google: Yes we do compute and use author quality. We don’t know

who anyone is in real life :-)

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)

How the Search Ranking Factors Have

Changed in the Eyes of Experts

http://www.seomoz.org/article/search-ranking-factors

New data will be available on SEOmoz in April, 2011

Big Changes from 2009 to 2011

The new version of the ranking factors will be online in April, 2011

• Link-Based Factors are no longer 60%+ of the equation!

• Social Data is perceived to be a significant player

• Page-Level Link Metrics Fell the Most (43% - 22%)

• Keyword-Level Domain Metrics, Brand Data + Social Rose

• The Survey itself asked for more detail/specificity(which may be responsible for some of these shifts)

A Look at Google’s “Farmer”

(aka “Panda”) Update

Sites that Lost Visibility

Sites that Gained Visibility

http://www.seomoz.org/blog/googles-farmer-update-analysis-of-winners-vs-losers

From the Mouths of Googlers

http://www.wired.com/epicenter/2011/03/the-panda-that-hates-farms/all/1

Wired.com: How do you recognize a shallow-content site?

Singhal: (W)e asked the raters questions like: “Would you be comfortable giving this site your credit card? Would you be comfortable giving medicine prescribed by this site to your kids?”

Cutts: (Using) a rigorous set of questions, everything from. “Do you consider this site to be authoritative? Would it be okay if this was in a magazine? Does this site have excessive ads?”

Singhal: And based on that, we basically formed some definition of what could be considered low quality.

From the Mouths of Googlers

http://www.wired.com/epicenter/2011/03/the-panda-that-hates-farms/all/1

Wired.com: But how do you implement that algorithmically?

Cutts: I think you look for signals that recreate that same intuition, that same experience that you have as an engineer and that users have.

Singhal: You can imagine in a hyperspace a bunch of points, some points are red, some points are green, and in others there’s some mixture. Your job is to find a plane which says that most things on this side of the place are red, and most of the things on that side of the plane are the opposite of red.

Keyword Stuffed Titles + Pages

Anchor-Text Rich Internal Links

Navigation for Engines, Not Humans

Generic Design and Layout

Anonymous Contact Forms

Ad Blocks Dominating the Page

Reciprocal Link Pages Paid Links w/ Manipulative Anchor Text
