As an advertiser I'm looking for a solution to detect click fraud.
I have found some websites offering click fraud detection solutions. For example:
I'm advertising via a lot of different PPC networks and would like to be able to create reports per PPC network containing 'proof' of click fraud that is excepted by most PPC networks (in order to get a refund and/or to block fraudulent traffic sources within a network).
Has anyone tested and/or still using click fraud detection solution? Any recommendations?
