For those AFFECTED, are yours similar, better or worse?
Now that is far too much of a co-incidence (for eCPM and Earnings anyway).

Whoa...who else is looking at similar figures, scary, scary.
castar - Who do you think you'll replace them with? We don't have much option in the UK that's why we're creating our own ad network.
BUT, I have done some things in an attempt to increase those numbers, I didn't sit idly by. I implemented a new design on one smaller site which increased it's CPM by 46.6% (yeah!), and removed an ad unit from a few pages that had two units. So if I hadn't done those changes my numbers would be closer to yours.
I feel like I'm not out of the woods yet. I have tons of channels and I'm slowly reviewing each site and channel and seeing what I can do to get the CPM up. I'm also looking into other companies, have already signed up for 2 - directmedia and I forget the other, I stopped using them already :-)
I know it's still "short" sample (1 month) and there has been special days and holiday-weeks... but still, surprisingly similar numbers.
It would be intresting to compare other variables (to be useful it would require exchange of quite sensitive data), like where you are located (both you and your servers), what sector are you in, how do you promote your site etc. To see if there is one or more things in common.
I think we should revisit this topic at the end of the months because the data above just misses out on the glitch days of October (which started Oct 20-21 onwards).
Page impressions -4.05%
Clicks -30.32%
CTR -54.2%
eCPM -63.45%
Average daily earnings -67.12%
Does anyone think this glitch will be corrected?
if yes, any idea when?
Also, please suggest alternates to adsense, I am from india, hence YPN cant be used here..
Page impressions : -4.8%
Clicks : -4.3%
CTR : -0.3%
eCPM : +22.4%
Earnings : +16.5%
One more tiny detail to support my 'SERP (2-data-sets-were-combined) -update was all about continents/countries'.
Maybe everything is more geo-targeted, meaning that global sites lost and "sort-of-local" sites may actually have gained...
page impressions - 120%
clicks - 113%
CTR - 95%
eCPM - 51%
Earnings - 61%
EPC - 54%
Page impressions +4.59%
Clicks -29.44%
CTR -33.49%
eCPM -24.65%
ePClick +10.42%
Average daily earnings -25.90%
Chapman-
What's more, the previously "foolproof" method of raising eCPM by eliminating low eCPM pages just isn't showing the same kick. We see this more as a cap than as a glitch. Just wished they had capped us at our average rather than 60% of our average:-)
page impressions - 120%
For example, if you had 100K impressions last year and 20K impressions this period, then your decrease would be 100-20/100 = 80%. To drop 120% would mean it went from 100K down to -20K. Any decrease greater than 100% takes you into the negative.
Or are you using dashes as opposed to negative signs? Perhaps you mean a 20% increase over last year? Maybe I'm the one confused here ;-)

Also I don't see why page impressions is being brought up at all. That's a product of gross traffic and not related to AdSense. Even Google SE referrals have no relation to anything going on in AdSense.
Also I don't see why page impressions is being brought up at all.
Because if Google doesn't have enough inventory to show then Page Impressions will go down since they won't rotate the ads as much therefore the PI's could be an indicator of reduced inventory or, as in my case, my traffic usually reduces about 10% overall through Nov until Xmas therefore when people are trying to compare information we need to make sure that we are comparing like with like.
Does that make sense what I've written?!
As compared the the same period last year:
Nov 1 - Nov 21
page impressions - 120%
clicks - 113%
CTR - 95%
eCPM - 51%
Earnings - 61%
EPC - 54%
I think he means as % of previous figures therefore:
page impressions +20%
clicks +13%
CTR -5%
eCPM -49%
Earnings -39%
EPC -46%
Please tell me if I'm wrong!
Impressions + 5.83%
Clicks - 16.91%
CTR - 21.40%
eCPM - 13.11%
Earnings - 7.97%
Comparing to the same period last year would be even worse
Traffic up, everything else down.
about the same numbers here.
My CTR dropped about 20% on October 19th and hasn't recovered since then. EPC is slightly up but not enough to compensate.
Since then I'm observing many of those 'expanded ads' (only two or three ads showing in a rectangle) on my sites, which are more a scream in my visitors' faces than an incentive to click.
(Sorry for being off topic as I don't suffer from The Glitch as others do.)
Q: Why a sudden drop in CTR?
A: This is probably caused by a combination of three things.
First, I have noticed a change in the counting (i.e. the way Google determines whether a click is valid or not). This happened to me in September, probably as a guinea pig as very few others chimed in. Obviously, if Google does not display all clicks (because some are deemed invalid), CTR goes down.
Second, the change in clickable area might have caused this as well. As discussed in other threads, depending on the degree of blending, a site may be hit.
Third, seasonal effects are obviously an important factor. These can be eliminated in the analysis by comparing year-on-year values rather than intra-year values. (This again may only be valid if you are indeed seeing a similar behaviour of visitors every year.)
Q: Why a drop in eCPM?
A: This is probably the hottest question in the Adsense community (if there is such a group). I believe that Google wants to incentivize sites to show aggressive growth in order to keep up with their own growth (and specifically, their very own growth expectations put forward by analysts). Unless you run a UGC site, it will be quite difficult to achieve this kind of traffic growth. In my case, I'd need two to four times the traffic today to just keep the absolute revenue level of my best day (which occured in the first half of 2006). With a static site and classical content that kind of growth is unrealistic; with a dynamic site and user generated content it is possible. With such a site, it may even be possible to see growth of absolute revenue.
But as always, we don't know what we don't know, so it's just a theory of my own.

And last year's Oct. was off 50% from the Oct. before that... it is a steady down hill slide.
Mike
yet earnings are are inline with this month's daily avaerage. Go figure.What on earth is happening? Me too, absolutely spot on post-Glitch average earnings, CTR nearly pre-Glitch level, EPC at the lower end of pre-Glitch range however eCPM at the very top of post-Glitch level therefore still about 20% below pre-Glitch level.
I obviously have a new trading range value of +/-20% of average daily earnings that has been remarkably consistent the past two weeks whilst I have left the sites alone to see precisely what transpired.

Yep I posted in September that I had suddenly seen a big change in EPC values which suddenly bounced back.
Second, the change in clickable area might have caused this as well.
The Glitch was before the introduction of this surely?
Third, seasonal effects are obviously an important factor.
I can't agree with that since statistically it is most unprobable for a mass exodus like this PLUS we have to remember that many sites have not been affected. If it were a seasonal effect many more would be seeing anomalies yet thay are not.
For example, EFV's travel site has hardly been affected yet someone else's travel site has been hit with The Glitch penalty therefore I'm pretty sure we can eliminate seasonal effects.
Unless you run a UGC site, it will be quite difficult to achieve this kind of traffic growth.
An interesting idea however what type of ads do UGC sites run? I very much doubt they have my niche specialised construction products.
However you are totally correct about one thing:
But as always, we don't know what we don't know,
Thanks G, I'm now beginning to look like a mushroom!
This happened to me in September, probably as a guinea pig as very few others chimed in.
We took a 20% year-over-year hit at the beginning of the summer, which at the time I thought might be due to our experimenting with PPA or some other issues that turned out not to matter. Then we took a another 20% hit at the same time a lot of you saw a 40% hit. So if somebody is guilty for being a canary in the coal mine who didn't yell loud enough when Google started A/B testing how low they can go, it's us.
Sorry all:-)
