For May: -24%
I suffered from this before, but never that much.
I thought it were my text links, that were blended in well, so ppl could click them accidentally, and quickly return to my site. ( invalid click ).
So in May I removed those ads, and used image ads only. No mistake if they click those.
Result : -5% extra. (April was -19%).
I really do not know what to do about this.
I do not buy traffic, and never did.
My site is no review or commercial site, it's an educational site for children. Maybe that doesn't convert well enough for the advertisers ?
It feels like they slowly push me out of the Adsense program.
This is becoming a major problem, and not only for me as I read above.
