Bad links to your site damage google ranking (Disavow links tool)

Google at webmaster tools introduced a tool that enables you to disavow links to your site. If you’ve been notified of a manual spam action based on “unnatural links” pointing to your site, this tool can help you address the issue. If you haven’t gotten this notification, this tool generally isn’t something you need to worry about.

First, a quick refresher. Links are one of the most well-known signals we use to order search results. By looking at the links between pages, Google can get a sense of which pages are reputable and important, and thus more likely to be relevant to Google users. This is the basis of PageRank, which is one of more than 200 signals Google rely on to determine rankings. Since PageRank is so well-known, it’s also a target for spammers, and Google fight linkspam constantly with algorithms and by taking manual action.

If you’ve done as much as you can to remove the problematic links, and there are still some links you just can’t seem to get down, that’s a good time to visit the new Disavow links page.
