I'm surprised this topics hasn't come up yet. With the new deal with Microsoft and Yahoo how do people think this will affect PPC? While I haven't seen it definitively stated yet it seems inevitable that the two PPC platforms will merge sooner or later. Will this mean the days of low cost traffic from MSN and Yahoo are soon to come to an end? and will this now mean that it's cost effective to start using this platform for more clients? my immediate thought as someone involved in this field is that my clients will now want a presence on both search engines.
