Anyone have any data on the top 5 or 10 categories (i.e. travel, loans, real estate etc) which provide Google with most of its Adwords revenue? I am trying to get a feel for which industries are the players here when it comes to providing Google with revenue.
As an aside, recently it seems that CPC prices are rising sharply as more advertisers discover the Adwords tool. Anyone else seeing this?
Thanks,
