Are clicks reported in real time during certain periods and delayed for other periods? The reason I ask is that my sites will go several hours without any reporting of clicks, then all of a sudden I will get a reporting of a dozen or so clicks. I find this most often during the daytime (pacific standard time in the US) when I login to my Adsense account. It seems like during the morning and evening hours, I get continuous reporting, but during the day there will be several hours of no reporting (despite traffic being higher). Again this is across many sites so it's not for a small sampling. Does anyone have any ideas about what's going on? It's my guess that during certain periods during the day, clicks are not reported in realtime for whatever reasons (perhaps because of daily maintenance, updates, etc on their end)
I'm experiencing the same. From morning to evening, usually there is only 25% of the average click rate. Then when I wake up the morning after, I see 3 times more clicks. I know for a fact that my traffic is on the same time zone as I am so that is not the answer.
