This thread http://news.ycombinator.com/item?id=790800 prompted me to go and do something that may be a technical violation of the adsense tos.
So, here it is (the month of July):
impressions clicks ctr ecpm total pay
6,798,064 13,694 0.20% €0.13 €882.30
This is a minor drop in the bucket on our sites income, we are not exactly advertising driven but since it is 0 work we figured we might as well take it.
The sites these ads run on are mostly music oriented.
Without knowing more about these sites I'm sure that you'll have a hard time using those numbers directly, but it may help somebody that is considering an advertising supported startup to determine the bandwidth of income that could be generated using google advertising.
Anybody else feels like sharing ?
I've never made a penny on Adsense, and probably never will. I think the ads usually look like warts on a site, and if you need to have them on your site then you have other, more serious problems. Unless maybe you're an open-source developer site or something. I think the argument that they are 'zero work' and 'free money' is ludicrous. I'm not against advertisements, in general, but I think Adsense often makes sites look like crappy, low-rent. low-content, spammy, rip-off sites. (And, yes, I'm aware of all the major media companies that use Adsense on their sites.) Another major reason I hate this type of near random text ad is that you rarely have 100% control over what is being presented to your audience...and I'm very picky about who I want to be associated with - even at the subconscious level.
Most importantly, every single time we have tested having Adsense or their ilk on one of our sites, it has lowered our overall conversions. Paying customers are worth more than the pittance you usually make from blind text ads, so we try not to make our customers feel like they should take a shower after visiting our sites.
