Do you mean clickthrough rate or $/click? The CTR I've gotten varies wildly by program. That said I'm above 10% on a certain large text-ad system. To be fair, the Chinese cars and Peugeots you are specializing in have limited appeal among Americans and that might be what's holding you back. Even the smarts are not yet sold in the US.
yea im talking the avg $ u get per click...and i think ur right, i never realized that, maybe my sites get little cause the IP's of the users are not from NoRTH America!... does google adsense pay differently depending on IP location???
