Magic SEO Ball says: Don’t count on it.
Magic SEO Ball appears to be skeptical about Bing’s invitation to webmasters to disavow spammy links pointing to their sites. This makes a lot of sense, as our friends at Bing also appear to be uncertain about how Bing treats bad incoming links. As Vanessa Fox writes:
I still don’t understand what a site owner gets in return for the time spent disavowing links with this tool. I can only conclude that Bing may in fact lower a site’s ranking due to spammy incoming links.
If this is true, it’s contrary to what Bing says about how its ranking algorithm works. Perhaps Bing simply would prefer for webmasters to do the dirty work and identify all the bad links to save Bing the trouble.
