I login to my account in the morning today and I see 3 clicks 3.00 dollars, So I was really happy about it, and I say wow at night I will have so good money. Now I login again and what I see ? 16 clicks 3.50 dollars.... I dont understand how is that possible....
mate i have the same scenario here......my first few clicks of the day get me a good CPC.....but as the day progresses CPC falls, rise and falls and rise again......sometimes I make $3 with 6 clicks and othertimes i struggle to make even $10 with 100 clicks..... depends where you are getting your traffic from ( Asia is consider as cheap traffic i guess) and ofcource what kind of ads you are getting on your site........
The CPC depends on the ads which are clicked and how much Advertisers have bid for those ads. Normally the ads at the top tend to pay more compared to ads at the bottom. In your case, people must have clicked on the ads at the bottom of your ads eg. bottom of 160x600 banner and not on top so you are getting less CPC.
This thing is very normal in adsesne , yesterday i had login to my account and my earnings was : 9 clicks = 2.03 $ . But tonight my earning is 6 clicks = 0.020 $
3$ for 3 clicks is good . but i think that some had made you invalid clicks , and those clicks were not counted into your account. so such low earning
