Facebook ads are 'some of the worst performing ad units on the web'

It's not just General Motors that thinks Facebook ads are waste.

The CEO at the agency that does Web ads for Samsung, Welch's, and Klondike says Facebook ads are, "fundamentally some of the worst performing ad units on the Web."

John Coleman, CEO of The VIA Agency (named small agency of the year by AdAge), says that Facebook's "platform" – the free stuff, like brand pages – is an "integral" part of his clients' marketing campaigns.
