Same here. Stats look to be about 1/3 of what they should be.
I also noticed a huge difference between Google's page impressions and our server reports; 20% less for Thurs. and 40% less on Friday. Saturday's report coincided exactly with our server so hopefully, things are now back to normal. I had to pick this week to lauch AdSense on my site's 3000+ pages :-( sigh.
My page impressions match up now however earnings for Thursday and Friday are still way down. Saturday's earnings were as expected.
They definitely had an issue which they ought to clarify before the conspiracy theories start!
Read all the threads.
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.
Changed ratio ad impressions to page impressions
|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! |
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.
I also have 1/2 impressions.
clicks may be ok.
Our normal stats show a substantial increase in volume (for one of our sites it's the first time that Y's traffic has taken over G, BTW) over the last couple days, however Adsense impressions declined sharply, about 30% or so.
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.
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.
That would go in part to explaining the numbers but if that is indeed true then I have an average of 4 ads on each page. Hmmm, I know I don't. I'll analyse it a bit more.
as I posted on May 6:
>>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.
I generally have terrible CTR. On a typical day, I'll have 10 clicks on 20,000 impressions. Yes, I know, quite pathetic CTR. Yesterday I got 91 clicks and today I already have 44 clicks on just 4400 impressions. So I'm on track for normal impressions, but clicks are way up. Could this be for real? $1000/month would certainly be better than $50 =]
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?
If you switch to:
Show Data By[?]
"Individual Ad Unit" mode
you see consistent results before and after May 5th, and my observation is you could compare those results. But I wouldn't compare the "Show data by Page" results before and after May 5th, there is a substantial change. The page impressions do closely match my actual website log statistics and this is a first.
The "page impressions" might have worked in the past but then they introduced the "Links" ad unit and then Page impressions were no longer correct if you used that unit.
It would be nice if they would document these changes.
I have had lower impressions than logs would indicate the last few days, too. I've never run Adlinks or more than one block of Adsense on a page so it doesn't have anything to do with multiple units being counted before, at least for me.
As my stats have been flakey, in one way or another, since that outage last week, I am curious to know if others have returned to "normal" yet.
My impressions are back up, clicks are at a record high, and CPC at a record low.
Rum thing the AdSense fruit machine!
Stats now look correct... Something however was tweaked on 05/05/05. EPC way down. We do not run image ads on our site. Could this be a way of knocking down earnings for those who do not join the image ad program? Maybe a conspiracy theory - however, good for disucssion.
>>My impressions are back up, clicks are at a record high, and CPC at a record low.
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.

again getting really bad ups and downs on what is normally a very stable network - just like last week...
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...
I'd be curious if others monitor the specific advertisers (served on your sites) compared to CPC. I'm almost certain, at least with my sites, the quality of ads has been reduced to junk, the ebay aff-type AdWords players.
So far this month, I would have to say things have been fairly normal, except for Saturday, the 7th, which could be due to that outage.
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.
A lot of us have been experiencing declining EPC's with improving impressions and CTR. I just noticed that in my case, the steep downward spiral happened when G announced targetted site CPM as a new advertiser option. Now I suspect that in my field, advertisers find it more profitable to buy CPMs than pay for clicks. So my question is - are my CPM earnings already reflected in the earnings report/stats? Shouldn't G differentiate betweem CPM earnings from click earnings? I still can't get over the fact that a new and seemingly harmless option given to advertisers can drag a publisher's earnings by more than 30%.
|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.
I just cant wait for yahoo, the higher paying words in some categories will hopefully help.
It is now not worth updating sites or adding google ads to test. I am weening myself of even this site and checking stats.
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.

To those wondering about 1/2 impressions--read this thread -- [webmasterworld.com...]
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.
impressions are normal - but eCPM still down
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...
