Anyone know if this exists, or have thoughts on this?
But you can probably infer it. I see the same set of ads on most of the pages on my site, but I've learned via channels that my EPC varies widely, by about a factor of 10! I've already taken AdSense off the pages where it just doesn't perform at all, and I've identified a type of page that does particularly well, and will try to write more of them.
You could do a similar analysis for your site. If you find that EPC doesn't vary much from page to page, maybe you could try something different and broaden the range of the site. Try adding pages that take different approaches or go into information that's a bit tangential to your main topic, but still related...
What would be nice is something a bit more than "guessing". We KNOW the CTR for pages and can tune accordingly. It just seems that if our revenue can be so greatly affected by SmartPricing, that we should be given some form of real, hard numbers to allow us to understand what we are doing "right" and "wrong" according to the Google "rules" of the system.
I'm also not sure it would be as useful for us as you assume--conversion is also affected by what the advertiser does on THEIR site, and we can't control that. What matter is what is happening on our sites.
And yes, low-bidding can affect EPC, but still, if you have variations in EPC by page, there must be something to be gained by adding more high-EPC-type pages, and deemphasizing the pages that don't do as well.

I've been thinking about this alot... because I've seen it too. And I've seen it across different sites of mine!
I'm beginning to conclude that what I'm seeing isn't necessarily smart pricing, but different bid levels for different keyword combinations. Same ad, but different bids because the keyword combos might vary slightly from page to page or site to site.
Just a thought.
