What's a search marketer to do when she's exhausted all of her likely keyword options on Google, Yahoo, MSN and even Ask -- and the client still has more money to burn? Loren Baker suggests trying one of these 8 alternative paid search engines.
From straight PPC providers MIVA and 7Search, to the newer, "more social" offerings like Facebook Ads and MySpace SelfServe Ads, these services can expand the reach of a paid search campaign -- exposing it to a different audience and typically at a lower cost-per-click.
Baker notes that the social newcomers have become more relevant since the practice of SEM has begun to branch into behavioral and contextual targeting. Managing to get these auxiliary campaigns ahead of the competition can be a significant advantage.
