This new pricing google has introduced for made for adsense sites, is it just for high paying keywords or is it really any site that Google deems was made for no purpose other then to show adense ads. Also, what criteria do they use to group a site into this category...is it a site that is very new with lots of pages, or do they track advertiser satisfaction rates from the hits from incoming links...
I'm sure it's a little bit of common sense and advertiser conversion rates. I mean even if a site is made AdSense, if the conversion rate is high, they I'm certain Google would be thumbs up.
I'm guessing you are refering to Smarpricing. You should do a search and then you'll find lots of threads on the subject. Basically it refers to the conversion of ads that are displayed on your site. If the ads have a low conversion you are most likely to be smartpriced meaning that you get payed less for the ads. Conversion means that the visitor clicks on your ad, goes to the advertiser and does something (buys a product, download something, register etc.). Most made for Adsense sites have a low conversion seeing as people are "Escape clicking" or that the traffic those sites receive aren't very targeted.
