On June 19th, 2008 I have added a quickpost that is more as an alert to Google’s webspam properties as Hey Google! Wake up! Google’s servers to Host SEO Spammers Work.

Ah, yes add to all of this the impolite comments on YouTube that are written in latin character most of the time but when you read it in French, Russian, Chinese or Arabic, it turns YouTube into an insult gallery.

Data from search logs is one tool we use to fight webspam and return cleaner and more relevant results. Logs data such as IP address and cookie information make it possible to create and use metrics that measure the different aspects of our search quality (such as index size and coverage, results “freshness,” and spam).

Whenever we create a new metric, it’s essential to be able to go over our logs data and compute new spam metrics using previous queries or results. We use our search logs to go “back in time” and see how well Google did on queries from months before. When we create a metric that measures a new type of spam more accurately, we not only start tracking our spam success going forward, but we also use logs data to see how we were doing on that type of spam in previous months and years.

The IP and cookie information is important for helping us apply this method only to searches that are from legitimate users as opposed to those that were generated by bots and other false searches. For example, if a bot sends the same queries to Google over and over again, those queries should really be discarded before we measure how much spam our users see. All of this–log data, IP addresses, and cookie information–makes your search results cleaner and more relevant.
