With the release of the Penguin update, Google started to count bad links as a negative ranking signal. Websites that purchased backlinks or gained backlinks through spamming (blog comment spam, forum profile backlinks, etc.) were penalized by Google
Many webmasters worried that other people might create bad backlinks to harm their website rankings. The new disavow link tool enables webmasters to tell Google that particular links should not count.
1. The disavow links tool allows you to indicate to Google which links you would like to disavow, and Google will typically ignore those links.
2. When you inform Google about bad links, Google sees this as a strong suggestion rather than a directive. After submitting your links, it will take several weeks until Google processes your request.
3. If you’ve received notice from Google that you have a manual action on your site then you still have to file a reconsideration request. Just submitting the links won’t help.
1. The tool is for people who used spammy methods to promote their websites. As an example, Google Matt Cutts names blog spam, comment spam, forum spam and guestbook spam.
2. In general, all tools that automatically create backlinks are spamming tools. If you used such a tool in the past, you should try to get rid of these backlinks.
3. If you followed our advice in the past, then you do not need the tool. If you used spam-free methods to promote your site then you don’t have to worry about this.
Google’s Matt Cutts says that you should think twice before using the tool:
1. “So don’t just immediately think, ‘Disavow is the answer for all my ills!’ You’re also going to want try to remove stuff off the web first. And this is a power tool.
2. It’s something where it is possible, in the process of telling Google to ignore links to your site, to make mistakes. So I would approach it with caution. I wouldn’t just jump in.
3. If you are a Mom and Pop, if you haven’t used your own SEO, if you haven’t used random link networks that you found on SEO Forums, this is probably not something that you should be using. I just want to try to reiterate that. Hopefully, everybody can remind everybody else of that people are talking about it on forums or conferences or whatever.”
