“Essentially, we've been doing the same kind of search now for over a decade, right? It's basically anchor text and PageRank and inbound links, and that's how we've kind of decided what page is best for a particular term… But there are signals beyond this.”

Stefan Weitz, Director for Bing Search

Matt Cutts, Head of Web Spam, Google

“One piece of advice I give to SEO masters is, don’t chase after Google’s algorithm, chase after your best interpretation of what users want, because that’s what Google’s chasing after,”

http://www.nytimes.com/2011/02/11/business/media/11search.html

Rand Fishkin, the Wizard of Moz

Every 3-4 years, there's a big shift or addition to the key metrics Google (and, to a lesser extent MSN/Bing and Yahoo!) uses to order competitive search results.1996-1999: On-page keyword usage + meta data1999 - 2002: PageRank + On-page2002 - 2005: Anchor text + Domain name + PageRank + On-Page2005 - 2009: Domain authority + Diversity of linking domains + Topic modeling + Anchor text + Domain name + PageRank + On-Page

Topic Modeling

Topic Modeling

Topic models provide a simple way to analyze large volumes of unlabeled text.

A "topic" consists of a cluster of words that frequently occur together.

Topic Modeling

http://neoformix.com/archive.html

Using contextual clues, topic models can connect words with similar meanings and distinguish between uses of words with multiple meanings.

Why Engines Need Topic Modeling

Term Frequency & Inverse Document Frequency

Co-Occurence

Causation? Not So Fast!

Perhaps, good links are more likely to point to pages that are more "relevant" via a topic model or some other aspect of Google's algorithm that we don't yet understand naturally biases towards these.

It’s Relative

•Don't presume that getting a 15% or a 20% is a terrible result

•Some queries simply won't produce results that fit remarkably well with given topics

Out of the SERPs!

Keyword spamming might improve your LDA score, …but not your rankings

Compare Your Friends

There’s Still Lots of Work to Do

• Correlations are good, but don’t get carried away – we haven’t reversed the algo

• We have built a tool to help grade & improve page content

• YOUR in-field results will tell us whether it can really help improve rankings

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)
