Adsense not paying?

Hi, I though this would be the best spot to ask this question as its been confusing me lately.
It seems that a large part of my clicks on adsense are actually earning me no money. Whats up with this anyone else have this issue?

 

Averaging $0.31 per click today, so I would say it works well

 

They don't always pay you for clicks, they change between CPC and CPM ads based on what would be most profitable for them.

 

May be these are invalid clicks?

Anyway, how do you know that a large number of clicks are making no money?

You see zero earnings?

 

I am facing the problem that i have many visitors in a day but the clicks on my ads aren't so good

 

Before writing such kinds of questions you have to write the niche your site has...How long have you been trying to earn money...Details...needed

 

if clicks r paying 0$ it means they r public service ads or invalid clicks

 

The minimum click is 0.1$ for all niche! but surprised to see you are not getting anything for clicks
