The latest ‘SEO Book’ blog post is titled “Google Disavow Tool”.

Aaron Wall says, “Google launched a disavow links tool. Webmasters who want to tell Google which links they don’t want counted can now do so by uploading a list of links in Google Webmaster Tools

If you haven’t received an “unnatural link” alert from Google, you don’t really need to use this tool. And even if you have received notification, Google are quick to point out that you may wish to pursue other avenues, such as approaching the site owner, first”.
