"Competitive brand keyword bidding in Google (where it is allowed by their trademark policy in many countries) is fairly common," said Kevin Lee, CEO of search consultancy Didit, in an e-mail interview. "However for many competitors there is an unstated agreement not to bid on each other's keywords because the only one getting rich is Google."
