in the attached image: 1+1+1 ... is showing as 2? similarly, the earnings aren't summing up correctly? does this mean that google has disregarded a click here?
no, it probably means that you are reading your reports wrong My guess those first two channels are showing earnings from the same ad, I concluded that from the same ammount earned for click. Go to your adsense advanced reports and select Show->Agregate Data, that will show the exact amount you have earned And congratulations for that $1.20 click
timing issue also..when you sum up your clicks they don't add up. Its to do with being in between their validation IMO. I use firefoox with a plug in of Adsense Notifier and clicks when summed up always lags to that of commissions.
Can't find the post anymore but it was because of using an url channel and a standard channel... both channels would show a click, but there was really only one.
I have the same on occasion. Try checking the stats after the day ends. Google says that only after the day is off, the stats can be considered reliable.
