Since the roll outs of Panda and Penguin algorithms by Google, many website owners have been scrambling to figure out how to get their ranking positions back. If your website was hit hard by these updates, chances are you where penalized for poor content, stale content, non-original content, bad links, or a combination of these. Many webmasters tried to improve the Page Rank of their pages by gaining links from anyone who would link to their site, and by purchasing links from “SEO Companies” that specialized in selling links from other sites. Sometimes these webmasters participated in link exchange programs, such as 3-way links, 5 for 2 links, and other link building schemes. For the most part, these are all schemes. The intent was to trick Google (see my article How to Trick Google) into believing your website was very popular.  Eventually Google catches on to most schemes out there and algorithm updates penalize these “black hat SEO” tactics.

So, what if you have a bunch of links now pointing to your site that you believe are low value or may be hurting you?  Google has rolled out a new tool in Google Webmaster called the Google Link Disavow Tool.

Do you need to use this tool?  Here’s a statement pulled directly from the Google Webmaster Tools Blog

Today we’re introducing 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.

Use this tool with caution.  Make sure you take the time to read Google’s documentation so that you don’t end up removing links that are relevant and beneficial to your site.
