The first line in an open letter from research firm Forrester to Facebook CEO Mark Zuckerberg is: "Facebook is failing marketers."

On-site ratings and reviews, search marketing, and e-mail marketing got the top three spots.
For its part, Facebook appears to be trying to boost marketing. In August, the social networkand last week it amped up mobile ads by . As of this week, Facebook will also be .
