I've heard rumors that there are techniques to lower CPC rates in adword campaigns. Are there any old threads that can validate these rumors I've heard?

Are you referring to "Bid management Software", or other practices?

I've heard things such as by adding more high traffic terms you can lower your PPC for other terms that you're targeting. Is there any truth to this?
