Adgroup management software

looking for more than bid management

[mchipman]

This isn't a Google-specific question, by the way...

None of the PPC bid management software I have seen has tools to help manage ad copy and/or landing pages. It's great to be able to change bid amounts, jam competitors, yada yada yada, but when you couple PPC management with multivariant (A/B) testing, it helps to have an easy way to manage content as well.

Does anyone have any suggestions?
