CMO Jeff Hennion said it's more cost-effective to drive people there via email, direct mail, or even TV ads that show a link to the Facebook fan page.
A ComScore report last July said 32% of P&G's internet display impressions were "socially published," most of which occurred on Facebook.
Facebook ads need a clear message, a promotion or call to action to be effective. "Delivering traditional brand-building or product messaging simply doesn't work. At all," he wrote in an email.
