Other than Spyfu, can anyone please point me to a resource that indicates how much specific keywords are going for in terms of bidding, on Adwords and similar PPC programs? I find that Spyfu does not return cost results for some keywords, while indicating that there are a bunch (21 being the max listed on Spyfy) of advertisers bidding on a certain term.
Can anyone please advise?
