Okay, so let's pretend i have a site about "Dogs". My main business, however, is insurance. For some lucky reason, I appear on top for "insurance". Then one day, company B appears and they beat me on Google. So, one way to harm their backlinks is to create many from unrelated niches. I.e. I could create links back from my dogs website to my competition's website.
I actually did this by accident to myself, so i know: It killed my site's rankings and even got banned from Google for a while. So basically, my dogs website, with it's massive traffic, is a grenade, waiting to get thrown at a site. By directing bad traffic, I can kill someone's site. And worst of all, they will think they are getting a LOT of traffic, when actually, I'm screwing them in the long run.
So my questions are....
- Am I right? This would kill PR, or was the time it happened to me purely a fluke (it was so bad, that if you typed in "dogs" followed by my country name, my site would appear 4th, even though it probably doesn't have the word dogs on the entire site once).
- How legal is this? (i'm scared this is a normal blackhat seo tactic that already exists.... is it?)
- How can something like this boomerang?
- Why is no one doing this? Or are they?
