Nope. Just for us to tell you ;-)
Okay, help me out here, what is CPM? Cost Per "something" I would guess.
M is the roman number symbol for thousand, and you will often find it used in reference to online advertising.
Aha! I've known it meant thousand for a long time, but I never knew why it was an M instead of a T. Thanks Jenstar!
<g> doest pay CPM, it only pays for clicks (CPC)
CPM = paying to display an ad 1000 times
CPC = paying for getting a click on an ad
The question was what is the effective CPM. Regardless of how Google pays...CPM, CPC, or whatever, you can still calculate your Adsense CPM as follows:
CPM = Earnings x 1000 / Impressions

If, after that little spat, let's go back to the topic...
..... I cannot help but notice that irock does not volunteer a figure for their own CPM. ;)
Personally I find CPM a very useful figure as it is mathematically a function of CTR and CPC. Often one of those goes up, but the other goes down.
I use Excel to give me a daily figure for CPM based on a 7 day moving average, which smooths out the obvious weekly cycle to AdSense (for tourism sites anyway.)
The number of impressions you put out is (broadly) within your control, rather than AdSense's control. So I have a separate daily 7 day moving average for impressions.
The two graphs give a good indication of whether you have a problem, and if so whare.
On a personal level, I have not seen any fulfilment of the prophesies of doom that are sometimes expressed on this board!

Which was appropriate considering the question he asked. And yes, it is a violation of the Adsense terms to disclose your stats.
What I can say, to answer irock's original question (maybe a little tangentially) is to say that the equivalent CPM of AdSense on my sites outperforms my other agency (non-targeted banner ads) by a factor of 7x - and it doesn't matter whether you measure it in $US, Euros or good old GB Pounds :-)
From what I have been hearing from others, I agree with devlin, AdSense appears to be well outperforming all the competitors. If you look back to older threads in this forum, there was a lot more discussion about this aspect, because people were dropping other advertisers in favor of AdSense.
Ok, here is a little thought:
3 sites, together producing around x impressions have y CPM. I now added a new site, more focused and in a high cost ad industry. This site changed my over all impressions to 1.25x, so has only a quarter of the impressions of the other sites combined, but incresed my CPM to 2.5y.
Morale is that topic to topic and site type to site type the potential for AdSense varies greatly, surely by an order of magnitude in the extreme ends.
