Once you identify which bad backlinks to remove, the next step is to submit a request to Google to remove them. You need to try to contact the webmasters and ask them to either remove the links or add the nofollow tag, so that no pagerank is passed. When everything else fails, use the Google disavow tool. Basically, the Google disavow tool is a feature that allows you to upload a file to Google with a list of links you don’t want Google to take into account. In the google webmasters, go to “Configure my site” and then select “Disavow Links.” Within the Disavow Links tool, use the dropdown menu to indicate that you are disavowing a page, directory, or domain URL. Enter the URL you want to disavow and click “Disavow.”
