I think channels stats are messed up because of some error at adsense part. I dont think there is anything to worry about.
Adsense channels are all messed up, i have 2 clicks today in the morning but only 1 of those were showing in the channels.
This is the correct answer. I contacted Google about a similar issue and they responded saying that the stats get fully updated once a day - at the end of the day. So, the correct stats will be yesterday's stats. Wait until tomorrow and see if you would still have this problem in your account.
Yeah, channels been messed up lately. Maybe you have adsense code on a site that you didn't insert channels on? You can also pull down from adsense setup to find out if clicks are from contextual or site
I've seen this once on a site that received low traffic at that time. When I checked the next day, it showed both impressions and a few clicks, so I guess it was just a reporting glitch.
channels are up and running now.... always try to mark channels to your ads then you'll not have clicks without impressions
With URL channels, I have every page covered (one URL covering a filesystem of files, not each individual page) My channel stats NEVER add up to my daily total. Not even after a week or two of "stats catching up". It's because clicks also come from cache, translated pages, etc.
