I've been registered with Google AdSense for more than half a year, but I haven't really displayed the ads much. Two weeks ago, with the launch of http://ntt.cc, I officially decided to start using Google AdSense. Google does not allow us to disclose actual earnings, so here I can only lament how cheap Chinese ad clicks are and marvel at the high price of English clicks. Regardless of match rate, click-through rate, or cost-per-click, the results show that the Chinese ad market is simply an insignificant afterthought that can be discarded... Today, I received an email from Google saying they have already sent the PIN code via regular mail. I'm quite curious about where the regular mail will be sent from; it surely won't be from Google China, right?
