More than 30% of SERPS for Some Terms - Spam

by Gilad on March 19th, 2007

Microsoft Research had recently released a paper [PDF] titled Spam Double-Funnel: Connecting Web Spammers with Advertisers. The paper categorized SERPS by industry and is showing that some categories such as drugs and ringtones include as much as 30% spam in their SERPS.

In outlining the manner of collecting these SERPS Microsoft Research noted:

In late September 2006, we submitted the 1,000 keywords to the Search Ranger system, which retrieved the top-50 results from all three major search engines. In total, we collected 101,585 unique URLs from 1,000×50x3=150,000 search results. With a set of approximately 500 known-spammer redirection domains and AdSense IDs at that time, the system identified 12,635 unique spam URLs, which accounted for 11.6% of all the top-50 appearances. (The actual redirection-spam density should be higher because some of the doorway pages had been deactivated, which were no longer causing URL redirections when we scanned which were no longer causing URL redirections when we scanned them.)
