i do click even if nothing's interesting even though ive become blind to them mostly, mostly because atleast someone wil get paid for that btw i only got 1 click till now and i made 1.17$ from that
I'm guessing not many click on them because ads are targeted to people who don't know much about them and just consider ads as part of a page not as a way to earn money... I never had adsense here because my account was frozen.
I clicked at least once in a week provided the ad is interesting. I am also getting very less number of clicks per month. (nearly 3-4 per month)
