Hey I am wondering if anybody has the scoop on the blackhat practice of de-ranking your competitors pages in the serps. I have been building sites and ranking well for a certain niche, but at the top of most of the highest searched keywords there is a guy with a page that eludes to the niche being a scam. He is holding the number one spot pretty firmly for a few keywords receiving the bulk of the traffic for this niche. His page serves as a pretty big deterrent to anyone doing research on whether or not they would like to buy. I am wondering if there is some sneaky blackhat practices I can put into use to get him de-ranked. I am tired of him shoo-ing away customers.
