noticed this for the past 4 days: ::Edited but i have around 5000 impressions with zero clicks:: seems kinda amazing that i have not had one single click? in the past four days....
Check your ad placement on your site... If it doesn't get the user's attention, it's possible. Also, it depends on the type of site. For example, forums get very few clicks. Also, it's against Google's TOS to post your stats BTW.
BrianK, I checked your AdSense placement and I must say that I did not feel that it was 'part of the site' which is what many of us are finding works better. Having it run down the left side of the page seems to work best, and I have heard that where you have yours place is the worst because it looks like an ad and the eyes skip over it immediately. IMO...
