This is an advanced feature and should only be used with caution. If used incorrectly, this feature can potentially harm your site’s performance in Google’s search results. We recommend that you disavow backlinks only if you believe you have a considerable number of spammy, artificial, or low-quality links pointing to your site, and if you are confident that the links are causing issues for you. In most cases, Google can assess which links to trust without additional guidance, so most normal or typical sites will not need to use this tool.

You’ll download a file containing all the pages linking to your site. Use this to create a text file (the file type must be .txt and it must be encoded in UTF-8 or 7-bit ASCII) containing only the links you want to disavow—one link per line. If you want Google to ignore all links from an entire domain (like example.com), add the line "domain:example.com". Your text file can include additional information about excluded links, as long as each line of description begins with the "#" character (all lines beginning with # will be ignored). Don't upload the entire list of links to your site: the text file that you upload is the list of links you want Google to ignore.

Note: Uploading a new file will replace all previously uploaded ones. It may take some time for Google to process the information you’ve uploaded. In particular, this information will be incorporated into our index as we recrawl the web and reprocess the pages that we see, which can take a number of weeks. These links will continue to be shown in the Webmaster Tools inbound links section.
