How might one go about reducing another site's google rank? I'm not interested in techniques which raise the rank of my site above the competitor, but techniques that would lower the rank of my competitor. Two thoughts: - Paid links are purchased to the competitor's site, a practice which Google frowns upon. I then report these paid links (http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=66736), which Google then acts upon. - A whole lot of spammy links are generated for the competitor, such at link farms. Not only will Google discount these links, but perhaps they punish a bit for them as well? Your thoughts and other ideas?
