On the downside, AdSense EPC is off about 7.5% from the same period last year (in contrast to display-ad and affiliate earnings, which are up). Still, it's nice to see a slight uptick in AdSense EPC compared to the last few months, especially during what's normally a slow time of year.
But here are my stats for October so far:
Earnings per click are up over the previous three months. CTR and therefore eCPM is slightly up from September '07, back to a a level that is just about average.
On the downside, AdSense EPC is off about 15% from the same period last year; what's more, daily revenue is down 33% (!) compared to last October. This really sucks, even though it's nice to see a slight uptick in AdSense EPC compared to the last few months, especially during what's normally a slow time of year.
Why care about EPC and eCPM?
eCPM is useful as a comparative measure. For example, if I know that Widgetco affiliate commissions deliver an average eCPM of $20, I may give Widgetco better placement than I'd give Whatsitco, whose affiliate commissions deliver an average eCPM of $10.
EPC is useful mainly in the context of this forum's endless discussions about whether advertisers are pulling out or bidding less, whether Google is "keeping more of the money," etc. We're constantly hearing from AdSense publishers who report a drop in their average earnings per click, so it's worthwhile to have examples of rising EPC if only to discourage assumptions about universal "trends" that don't exist.
