Yesterday one of my blogs got 21 page impressions , 5 clicks but 0$ in earnings. Why is this? My other sites generated me revenue but not this blog. Can anyone explain why this happened? 5 clicks and 0$
Hmm, I think 2 possible reasons. The click was somewhere in your area and all by one person, so it was smartpriced and negated by google or, like njoker555 said, it might have been a PSA, which gives you the advantage of knowing you donated about $1 to charity.
