Incoming links on other sites can affect Google’s ranking of your website. To eliminate low quality or spam links from your own site, you can disavow them. To disavow a link is to ask Google not to take the link into account when it ranks your site. The Google Disavow Tool is an advanced feature that’s useful if there are many bad links directing users to your site, and you believe these links are negatively affecting your ranking. Disavowing a link takes downloading a list of links that exist to your site, creating a file containing the links you want Google to disavow, and submitting it to Google.
