For the pas few months I have been watching over the CTR, dropping slowly from 1.5% to .29% sometime its .15% nowadays. I have statcounter tracking code and google analytics, statcounter exit link activity shows adsense CTR to be around 1% for my site with around 10000 impressions per day. but adsense only shows few clicks, that is 20 clicks for 10000 impressions. But few months back I was earning around $15 per day, now its only $3 average. what is happening?
