Pretty sure all my sites have been smartpriced. Don't understand why, I only have one adsense block on my sites, they all rank high in google for their keywords. So all traffic to the site is targeted and organic. Yet my clicks have went from anywhere to $1-$2 per click to 10-25 cents. like WTF How do you prevent or fix this BS.
You have nothing to do. I would go for another ad network instead of waiting for the things to be fixed. Almost all of the ad networks pay similar amounts for US/UK traffic. Adsense is the best one only for the sites which have not receive US/UK traffic.
