I have a few properties within a competitive niche. Also within this niche is a very tough competitor. We work diligently on building quality backlinks to our sites, and have not and do not buy links. The top competitor is clearly buying links, sometimes on shady websites (i.e. link farms, etc)... and in the 2 years I've followed them, I've never seen them get smacked by Google.
So, the question is, do I follow suit and buy links as well? I'm not keen on it as a practice, but you can't knock success. :confused:
