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.

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. Référencement Bing : tout ce qu’il faut savoir pour réussir.

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.
