Yahoo! to Limit Access to PPC API

Based on a post over at Smart Keywords Blog, AussieWebmaster reports that Yahoo! is going to lock down the API for the PPC Program. He says, "Right now no new SEM/Analytics companies are being allowed in, or the "not no, not now" response."He adds, that Yahoo! wants to take these types of services and products to a "higher level or more involved" in the space." Of course, this might start an uproar in the forums. AussieWebmaster has already begun a thread on this topic over at Search Engine Watch Forums.
