I have three websites in my Adsense account. The last two days i had ZERO clicks in ALL of them. And today i have clicks in all of them. All three websites are totally new with not more than 100 visitors per day each. I believe that adsense has NOT counted the clicks for the 2 days and today i see all of then at once....
Well the three sites are in a totally different niche. I have never seen in my (short) adsense life two days without a click in all of them. Of cource, it is possible but ....
(sh)it happens i had one day 3,5k uniques on my car tuning website and 0 CLICKS. the next day i had only 1,5k and 22 clicks that came with a lot of $$$ enjoy the dance with adsense. it takes years to obtain a stable income from it
Hmm....did the break in clicks coincide with the Super Bowl? Maybe your users weren't tuned in to your website...
I have about 7 websites in my account getting a combined total of 1000+- page impressions a day. Some days = 0 clicks...other times I will get 5 clicks. Don't worry
