Google made it possible to report spam results directly to them, and as they say, the sites will be removed from index if they in fact are spam. You can report anything that tries to deceive spiders by evil SEO.

Did you ever wonder why the hell some website gets a terrific search engine position, even if it has absolutely nothing to do with your specific search term. Those people use malicious search engine optimization, such as inbound spam links, hidden text and others.

If you're fed up with that, and would like the game to be a little more fair, report the search spam to Google. You can do this by browsing to Google's Report search spam contact list. Google says:

"We thoroughly investigate every report of deceptive practices and take appropriate action when we uncover genuine abuse. In especially egregious cases, we will remove spammers from our index immediately, so they don't show up in search results at all. At a minimum we'll use the data from each spam report to improve our site ranking and filtering algorithms, which, over time, should increase the quality of our results."
