The CPC has dropped by 50% today.. The page impressions and CTR is as usual.. but the income has dropped by half.. Terribly low CPC.. is this normal?
its not dropped buddy.... its up and down of google. Someday you make $50 and other day you'll make $15 have patience and it will be fine.
I have sites rolling from 1$-20$ a day with almost same amount of traffic / clicks. Good thing to spread your income on different niches, that why you will probably have a more steady income. Anyway end of month it its usually same $/click ratio anyway
