google webmaster Tools - Helping Google Help You

Webmaster Tools don’t just show you information – they enable you to take action.  For instance, you can tell Google whether you'd prefer to have the www or non-www version of your site listed in search results and you can ask Google to crawl your site at a different rate.  Want to get rid of an outdated sitelink that's showing for your site?  You can do that here as well.  The Webmaster Tools area also gives you a chance to let Google know about sites that are violating Google's Webmaster Guidelines.  We take these reports seriously, and while we won't necessarily take action on each specific site reported, we regularly use these reports to improve the overall quality of our search results.  What if your own site's presence in Google has been negatively impacted due to it violating our webmaster guidelines?  Simply fix the problem on your site, file a reconsideration request, and a member of our search quality team will evaluate the request and take appropriate action.
