I have implemented adsense, but I could not see adsense displaying ads on my blog while I can see the ad in other PC. Please help.
I believe this is how it's supposed to work. Otherwise, you will have an inflated number of impressions.
I think there must be something wrong with your code. I always see adsense ads on my site, when I check it out. Google filters out the impressions you make in the earning-calculation. Not beforehand.
