I am considering using a PPC management service like Marin Software Professional or Enterprise and was looking for cheaper alternatives whether on-demand or traditional software. We need PPC management, keyword expansion tools, automated bidding, tracking, etc with most PPC management services.
Marin Software Professional works for us except for one major factor - we dont have pixel based tracking so we need the ability to upload or FTP our own revenue data to better track conversions. Marin Enterprise has this functionality but the minimum monthly payment is several thousand dollars.
Does anyone know of or can recommend any services?
