I’m currently doing an experiment on how to reverse adsense smart priced. I suspected that I was hit by this at some point. Some adsense publishers were saying poorly converted visit to advertiser’s page may automatically results to lowered the value per click. But of course most of us doesn’t really know how google adsense work. Other publishers are saying low CTR would results to adsense smart priced while other are saying targetted content would avoid it. There are also some discussion that removing those adsense ads that you suspected is causing your account to be smart priced would reverse it to a higher value of ads per click. Hopefully, I can update this post in the future If can find something would benefit us.
