Many experts claim that posting a Facebook ad to your fans is a lot cheaper than posting it to non-fans (In terms of cost per exposure / per click).
They are NOT talking about the "boost" mechanism, cause this one shows your post MOSTLY to "friends-of-fans", but about creating an ad using the power-editor...
Have you tried it? Is it truly a lot cheaper than to advertise to target audience of non-fans? How exactly is it done?
Thank you, Roni
