Naturally, I wrote to Adsense to find out why I had clicks that weren't paid for.
The reply I received moments ago states that "recent changes" in the reporting system are responsible for this. That in order to "better align" clicks with revenue, invalid clicks may be included in the click total.
Obviously, with invalid clicks included, ctr will rise, but with zero revenue, EPC will drop, perhaps substantially.
