u Niche will be very low thats why.....bcz i am getting very gud per click rate on my technology blog.
You definitly have a low paying niche or some of the clicks were from the same person and therefore not counted.
Just low paying keywords, simple is that. If your getting a lot of traffic and not happy with the adsense amount for your niche, you could try to monetize it another way.
Damn. I've only had my site up for a few days now so I only got one click, but I got $1.25. As the others are saying, must be cheap ads. If you have a lot, reduce the number as Google will post the highest paying ads. The more ads, the cheaper each subsequent ad is.
