Adsense Low earnings with many clicks and visitors

Hi,

So I recently started using Adsense again on my website and I have a hard time understanding what's going on with it. Today I had over 2k visits, 20 clicks, a 0.85 RPM and still only earned 69 cents? Am I missing something here or is there something wrong? Click the white bar below, it's a screenshot but I don't know why it appears so small.

Thanks!

Your earnings for Jul 14th is accurate. If your CPC is 0.08, multiple it by 8 (clicks) : 0.08x20 = $0.64
However, for Jul 15th it's not. My guess is that Google viewed some of your clicks on Jul 15th as "Invalid clicks".
Are you clicking your own ads?

Do check out if you ads are targeted else wait for a month to review

It depends on lot of factors like what kind of niche are you into, visitors from which country comes to your site and so forth.
