Hi @Tushar_Ramani, CPC depends on various factors bro. 
We can blame the advertisers or our blog visitors, it could be anyone. We can definitely try to improve further, but it’s just a trial and error experiment.
Make sure you are using the most profitable ad sizes, it’ll help you to maximize your earnings via CPC & CTR. And don’t block any unnecessary ads, only block them if it doesn’t interest you or match your blog’s core topics.
