Hi, before my CTR was really low, about 0.10%, now it's good, but I still am wondering why my niche isn't paying high. Before, one click would get me about $0.50, that was when my CTR was low, now my CTR is good and my niche only pays about $0.06, am I being smart priced? I blocked all the low paying niches.
Sounds like your site may be of low quality - no offence! Or, it could be the fact that you are in a low paying niche, but you should be able to get over $0.06 per click...
