Shouldn't we assume that you are "derewarding" yourself by telling google what pays off for you? That they use this data in their adsense algos, effectively putting more expensive ads on that site. Increasing their internal value for that keyword. Whereas someone who manages their own ROI data internally has an advantage over the naive people sharing that data with G?
I know some people here have really analyzed this and I only use adwords for testing, so I could be way off.
Not sure use of this tool is naive... I certainly haven't seen any negative impact from it, only positives - as this tracking (despite it's negatives - mainly lack of aforementioned revenue data) is more accurate than other reporting tools that I have to pay for...
This would in essence hurt every site you advertise on because smart pricing is a determining factor in the amount I make as a publisher.
I have seen this portion of smart pricing as a flaw for some time - but for different reasons.
Wouldn't "not including" the ROI calculating code make it look like you never convert?
That would be a faulty algo. You would assume Google understands that some people are using the ROI system and some aren't.
OTOH, your argument could be that since you convert, they should display your ad more often.
But then you could game the system, put conversion code on any old page.
