Usually I would get a few cents when somebody clicks the ads, Today I've just received some exclusive content for my site, and got a little more visitors, which means a few more clicks, but I didn't make any money from those clicks? What could be going on?

Sometimes there's a delay in the showing of your earnings. I remember that happening to me.

And sometimes it shows the clicks but doesn't show the money. This happens when the Adsense algorithm detects false clicks. For example, if somebody double clicks on an ad, 2 clicks are registered but one of them is not accounted for.

I would recommend always getting things directly clarified from the Adsense team. I do this regularly.

If you have the new referal 2.0 adsense program then it will be per action.
Even if people click on your ads you might get nothing.

Sometimes it can happen that you don't see earnings for clicks on the normal adsense PPC
