Google improves spam detection and Eric Schmidt cashes out

24 01 2011

Matt Cutts recently made a blog post on the official Google blog, which highlighted changes in relevancy ranking factors to come:

As we’ve increased both our size and freshness in recent months, we’ve naturally indexed a lot of good content and some spam as well. To respond to that challenge, we recently launched a redesigned document-level classifier that makes it harder for spammy on-page content to rank highly. The new classifier is better at detecting spam on individual web pages, e.g., repeated spammy words—the sort of phrases you tend to see in junky, automated, self-promoting blog comments. We’ve also radically improved our ability to detect hacked sites, which were a major source of spam in 2010. And we’re evaluating multiple changes that should help drive spam levels even lower, including one change that primarily affects sites that copy others’ content and sites with low levels of original content.

 

And in other news:

  • The soon-to-be ex-CEO of Google, Eric Schmidt has submitted paperwork to clear the way for a stock sale worth about $334 million, this would represent 534,000 shares, leaving him still with 8.7 million shares.
  • This post from Google mobile blog, “We recently shared data on the explosive growth of the AdMob network last year. In 2010 we saw ad requests quadruple with every region and almost every country in the world contributing to that total growth number. Since then we’ve had a number of requests for a more detailed breakdown of exactly where in the world the growth is coming from. While the AdMob network generates monthly ad requests from more than 190 countries, 17 countries account for more than 80% percent of total traffic in December 2010.
