Though the page impressions are down by 50% CTR is up by a large amount making eCPM unusually high on Thursday, Friday and Saturday. Google did say there could be a 24 hour delay in updating stats... but it's much more than that now. Google, please fix it!
They definitely had an issue which they ought to clarify before the conspiracy theories start!
It's complete clear, that they reported before to much page impression.
The best theory tells, that AdLink impressions had been counted as page impression in addition.
That's now fixed.

Oddsod,
Your comment sums it up - I am dealing with fairly large predictable numbers.
It is my page impressions that are down since Thursday - my normal stats show no decline in vistors, nor do I appear to be getting any surge in public service ads (OK, in my case I have an alternate set, but you know what I mean)
IMHO summit is broke, and I don't think it is me.
You are probably aware that not only did we have AdSense and Adwords stats down this week for 15 hours, but also Google itself was down in its entirity for a while last night (apparent a dns problem, but nobody appears sure yet)
Troubled times at the plex.
clicks may be ok.

Your CTR and eCPM in the past was sort of "per ad" impression. There is now a "Page CTR" stat when showing page data. It looks like on Thurs May 5th they finally fixed the page impression statistics, so your CTR and eCPM may be double or more from now on.

>>If you have had adsence and adlink on the same page, the page impressions counted twice.
I still think, that's the case. Google had to correct it, due to the fact that they have to charge advertisers and pay publishers correctly for image ads.
The question now: How can a publisher find additional revenue from image ads in his stats?
At the same time when Google changed counting PI; I have put immage ads in addition to text ads on 2 sites. The result: earnings up by 50%. And what's interesting, on Google stats i found more clicks than on my internal reporting system, which is very accurate. E.g. 600 clichs/day compared to 670 clicks/day.
It would be helpfull if Google could comment how to control revenue coming from image ads.
Adsense has always been miss-counting (over-reporting) page impressions. They must have been showing some sum of ad impressions as mentioned in an earlier post.
Had that been the case, let us assume for the sake of arguement that it is true, then my income should not have been effected by such a change
Basically my impressions are down, but CTR and CPC (and hence eCPM) are normal. Therefore by logic, my income is down in line with AdSense impressions being down.
As I said above, log files show no such fall in pages put out, therefore I believe I am correct in deducing that it is a straight fall in AdSense impressions that has cause such a fall in income.
One thing that makes me skeptical is that yesterday I also installed phpAdsNew to rotate my ads. Anyone know of a situation where phpAdsNew leads to faulty clicks? I cannot imagine why it would. Any thoughts?
Thanks,

My impressions are back up, clicks are at a record high, and CPC at a record low.
Rum thing the AdSense fruit machine!
My clicks and impressions are at an all time high also. However, I'm seeing really low-buck ads, the better paying advertisers I normally have have been rotated out. I would think this is what has affected my CPC of late.

today was finally "back to normal" - then all of a sudden - for last 4 hours same pattern = our strong performing relevant useful high traffic sites dropping 60% off eCPM and - and our low content low traffic under development sites earning unusually high eCPM...
they are obviously testing something - plugging in - unplugging etc... whatever it is makes me nervous...
Today looks low but it's really too early to tell.
The only strange ad I see is a singles-related ad, way off topic for my site, showing up in the #1 position on a number of pages. They must have bid on a lot of keywords to get exposure. It won't be getting clicks, at least on my site.
I'm almost certain, at least with my sites, the quality of ads has been reduced to junk, the ebay aff-type AdWords players.
I'm seeing a lot more junky ads (less-targeted, and those that are targeted are more likely aff.-type ads) lately, which corresponds to a large decline in earnings over the past several days.
This has happened every now and then since I started adsense 18 months ago and I no longer go crazy trying to figure it out any more. I usually wait until the cycle changes back.
I also have 1/2 impressions.
I found this thread for this very reason. CTR has remained pretty stable, but the impressions seem to be half of what they should be. On or around May 5th (actually this date seems to be a hybrid), I noticed this change.
Friday through Sunday are slow days for me so it is hard to draw conclusions. But yesterday May 9th, was nearly identical to May 2nd yet the impressions were half.
My traffic has not changed. It may show, but hasnt. 4 diff sites, and i dont care if google says i cant post these stats.
First 10 days of this month =
Totals 3,800 354 9.3% USD18.29 USD69.50
Averages 380 35 USD6.95
April
Totals 6,684 562 8.4% USD15.19 USD101.52
Averages 668 56 USD10.15
March
Totals 6,851 758 11.1% USD26.09 USD178.77
Averages 685 75 USD17.88
Then check and see if you have a new option on your reports page.
Regarding the new CPM ad option affecting EPC. I doubt it. They are still testing. From what I've read on the AdWords forum, this isn't available yet to most advertisers.
Seems that we are also getting a few poor quality ads showing... really bad geo-targeted ads from overseas... "search" sites... some affiliate programs..
these may be the CPM ads being plugged in...?
i'm guessing what Google does is to show these "test" CPM ads and guage response rate in order to evaluate the "better performing ads"...
the result is a drop in eCPM that eventually gets better as time goes by and "better ads" are shown...
CPM seems to encourage advertisers to bid on unrelated keywords / geo targeting for wider exposure as far as i can see...
if this is so, expect a new batch of poor quality "test" CPM ads dumped on us on a regular basis...
we may be in for a long bumpy ride...
meanwhile i'm busy blocking these poor quality ads to hopefully salvage some CTR and eCPM... as i don't want these advertisers in my site...
