First,thank you for reply.I'm glad to communion with you.
I know the adsense heatmap,and my site is useing it.I have put the ad-link on the top and bottom ot contents.
Since the first of Aug , my earnings is increasing all the while.
Only yesterday and today is decreasing suddenly , and i am worry about the income of tomorrow.
Perhaps i didn't understand the google adsense heatmap indeed, Can you explain the heatmap for me?
(I'm in china,and my website is chinese.)
