Facebook Hashtags Not Open to Advertising — Yet

Facebook's introduction of hashtags paves the way for a lucrative stream of new advertising, but the company is not opening the program up to advertisers, at least not at this time.

Reps from the company confirmed that hashtags are off limits to marketers right now. However, there doesn't appear to be any reason why Facebook would block hashtag buys in the future. Facebook is, however, encouraging marketers to use hashtags in advertising and arguing that Facebook will now amplify a hashtag's influence. A rep stresses thought that "using them and buying them are different."
