Looking for a PPC AutoBid app..

Hey there,

Managing a massive keyword list is not cost effective and burns too much time when done manually.

I'm looking for a PPC management application or script that I can use to track and manage all my PPC campaigns that will also do auto-bidding which does not charge a monthly fee.

eg: I want to automatically stop a PPC campaign as soon as it starts costing more than the income it returns.

Everything I have found requires a monthly fee which I think is crazy. Why pay a fee when I can run an app on my own machine or my own server?

The only fees I want to pay are the google api fees.

Does anybody know of such a tool or script?

If it can also work with MSN, Yahoo and MIVA that would be excellent.

Thanks,
Sean
