GOOD SEO PRACTICES TO UNDO BAD LINKS
Is your website drowning under the weight of spammy links? You know what these are, the voluminous links from low quality sites that helped your inbound link numbers at one time but now are hurting your rankings.
In the prior SEO world, it was possible to send thousands of links to a site and the rankings would go through the roof. No more. With the Penguin updates of the past few years, quality has replaced quantity. You might still have some of these legacy links lying around, clogging up your Google Webmaster Tools link profile and creating a problem within your rankings.
What can you do about these spammy links? If you have a list, you can contact the site owner where the link is coming from and ask them to manually remove the link. This can be quite tedious, but is the best way to get the job done if you have fewer than 50 links or so. More links? Then your only resort may be to use the Google Disavow Tool that can be found within Google’s Webmaster Tools. Basically, you create a list of all the links that you believe are low quality and created without your knowledge or consent, and submit these links to Google. Does this work? Not all the time. Sometimes, site owners find that these links were not the problem at all and something else was causing the problem. Sometimes it does work and the site slowly starts to regain rankings bit by bit as newer, high quality links and content are added.

One note. Link spam can be malicious and is not owner or owner’s agent generated. In this case, it is best to use the Disavow Tool and to ask for a manual review of your site.
