I've come to the conclusion that there is no reason to pay attention to my adsense stats for the day, only the previous day. My US clicks don't seem to show until late at night when I prefer to be sleeping. This has been the trend for me all month. It looks really bad, then ends up "almost" average in "most cases", otherwise it remains garbage. So I can't take anything I see today as "real".
I think things will only improve when Google doesn't have such a large share of the search market. Personally, I haven't used Google Search for months now, preferring to go with an engine that does not record IP addresses. You'll have to hand it to Google making Google an everyday verb.
I've noticed the slow stats as well over the last couple weeks, which then end up about average to below average. I was wndering if there have been any patterns from others observed. I've noticed for example a decrease in CTR, which may have something to do with it. Has anyone noticed a change in targetting quality maybe?
Yucky Sunday, third lowest clicks, CTR and earnings day of the month, page impressions normal and even though it's early in the Google day this morning I am flat lining, apart from page impressions I'm reading zeroes across the board!
I have been loving Adsense since a week ago last Sunday. It's like a switch went off overnight and my eCPM doubled, and my CTR went up some. Things are back to where they were pre-Panda, but my traffic is higher, and so are my daily totals. I don't know if suddenly a whole bunch of advertisers rolled out their pre-Christmas campaigns, or what changed? I didn't change anything. The upswing coincided with the confirmation I can attend the Adsense in Your Town event in November (and I had to give my main site URL in the little application). Hmm.
I also had a dramatic downturn a few months ago, which coincided exactly with another G person checking out my websites. Someone had stolen all of the content from one of my newer sites, and I reported that to Blogger (owned by G), which was where the offending site was hosted. That site got all of their content removed, but suddenly my eCPM and CTR crashed and burn that same week. But I doubt the Blogger people work with the Adsense people - it was probably just a weird coincidence.
