Who can tell me what to do if my account is now smartpriced, should i take all adsense down , or can anyone tell me if there is a other solution?
It was reported a long time ago that taking down your adsense code for a few days could Un-Smartprice your account. However that's not allowed and some users got banned for doing so (if I'm not mistaken). Be careful.
Being smart priced is because your conversion rate is very very low and it's used to protect advertisers investment. Regardless what you do unless your conversion rate goes up you'll just keep getting smart priced.
