Facebook (FB) is eliminating its sponsored search ads as part of its efforts to get rid of over half its 27 ad products (and limit advertiser confusion). Facebook argues the ads were mostly used to promote apps and games, products that can be advertised via app install ads (growing quickly) and page post link ads. But it's still a surprising move, given expectations Facebook will ramp its search ad ops with the help of graph search. Meanwhile, a Salesforce report estimates the click-through rate for Facebook ads ranges from a mere 0.03% (dating ads) to 0.92% (telecom ads). Google (GOOG) once claimed the average rate for its AdWords search ads is around 2%.
