I have recieved such clicks many times . It can be for many reasons : Invalid click ads available for a specifical region MFA below 0.001 ......
Those MFA websites are a pain to normal adsense users as I think thats what made Google a bit more strict.
i get low clicks too sometimes but never 0,00 clicks. i've got once 0,11$ from 4 clicks and the next day i got $1,95 from only 1 click. so maybe tomorrow would be better for you.
0.00 happened more than once on my sites. I can live with that because there are certainly some good reasons for that. Problem is that when, in the beginning, I asked Google the reason, they replied that their policy is not to disclose such matters. Too bad. Now all we can do here is ... guessing and composing theories on the subject.
