From Wikipedia, "As of 2006, SEM was growing much faster than traditional advertising and even other channels of online marketing.^[2] Because of the complex technology, a secondary "search marketing agency" market has evolved. Many marketers have difficulty understanding search engine marketing and they rely on third party agencies to manage their search marketing. Some of these agencies have developed technology that automates bidding and other complex functions required for the Pay Per Click model. . "
