People have compared PageRank to a “random surfer” model in which PageRank is the probability that a random surfer clicking on links lands on a page. Other people think of the web as an link matrix in which the value at position (i,j) indicates the presence of links from page i to page j.
In that case, PageRank corresponds to the principal eigenvector of that normalized link matrix. Disclaimer: Even when I joined the company in 2000, Google was doing more sophisticated link computation than you would observe from the classic PageRank papers. If you believe that Google stopped innovating in link analysis, that’s a flawed assumption. Probably the most popular way to envision PageRank is as a flow that happens between documents across outlinks. In the image above, the lower-left document has “nine points of PageRank” and three outgoing links.
That simplistic model doesn’t work perfectly, however. Q: Why tell us now? Google Ranking Factors - SEO Checklist. Search Engine Ranking Factors. Every two years, Moz surveys the opinions of dozens of the world's brightest search marketers and runs correlation studies to better understand the workings of search engine algorithms.
We gather this data to gain insight into the factors that may help—or hurt—a website's visibility in search engines. This year, Moz surveyed over 150 leading search marketers who provided expert opinions on over 90 ranking factors. In addition, the Data Science team at Moz, lead by Dr. Matthew Peters, ran an extensive correlation study to determine which features of websites and webpages are associated with higher search rankings. For the first time this year, Moz partnered with several data partners to enhance the study, including SimilarWeb, DomainTools, and Ahrefs. Note that these factors are not "proof" of what search engines use to rank websites, but simply show the characteristics of web pages that tend to rank higher. Google I/O 2009 - Search Friendly Development. Death to Content Farms: Google Tweaks Algorithm to Find More “High-Quality Sites” — NewsGrange.
Google today made a major change to its search algorithm that will affect almost 12% of all queries.
According to a blog post written by the company’s Amit Singhal and Matt Cutts, this change is meant to highlight high-quality sites and push down “sites which are low-value add for users, copy content from other websites or sites that are just not very useful.” While Google doesn’t mention content farms by name, there can be little doubt that this update is directly aimed at them and scraper sites that just copy content. According to Google, this update doesn’t take any data from the Personal Blocklist Chrome extension into account, yet. The update does track well with the top blocked sites by Google’s users, though. Indeed, Google says the update addresses 84% of them, though it didn’t go into any details as to which sites specifically would be affected. For a more in-depth look at how this change came about, also take a look at Danny Sullivan’s excellent post on Search Engine Land.

He asked if I was available to come speak at a YCombinator SEO event in Mountain View. Tonight, I presented at that evented and thought I'd share my experiences, recommendations and yes, my presentation. Not everything that was discussed is public, in fact, much of it is "classified" at YC's request. However, there's so much good material that it would be criminal not to share. First up, my presentation from the YCombinator SEO for Startups event (naturally, hosted on YC company and prior SEOmoz consulting client, Scribd): SEO for Startups: YCombinator February 2010 Next, since it's hard to do any slide deck justice with just the slides, a list of top advice and recommendations, not just from the slide deck, but from many years of interactions, consulting and Q+A help for startups: SEO as a Strategy, not a Tactic Yelp uses SEO as a strategy.
