You are talking about for cell phones I imagine? If that is the case, I believe Google may already or has an upcoming debut of a platform to advertise on the Google search (mobile) for Adwords. Same concept as adwords except the character limits are much shorter, headlines will be 18 characters, description lines will also be 18 characters... That's what I hear anyways, but have yet to use it. Anyone else know more about this or other mobile marketing opportunities?
