Disavow links. It sounds like something you’d say in a Dungeons and Dragons game: “I cast disavow links, rolling my d20 to do a Search check.”
In reality, however, it’s a way for search engines and webmasters to seek out and destroy spam sites, and Google just launched its own disavow links tool today.
Incoming links to your website from a spam site can have disastrous effects on your ranking with the Google Gods.
What the disavow links tool does is simple. As Google puts it on the tool’s page, “If you believe your site’s ranking is being harmed by low-quality links you do not control, you can ask Google not to take them into account when assessing your site.” This is generally only something you’d use if you have received a notification about manual spam action taken due to spam links directing folks to your site.
The search giant’s Webmaster Tools will send these notifications if your site is linked to through paid links or other nefarious, spammy means and schemes. You can then upload a file of the bad links to Google for the remission of SEO sins.
Here’s our good pal Matt Cutts, who’s like, a level 19 battle sorcerer when it comes to spam-fighting, explaining more about the disavow links tool:
