What does it mean if your AdSense report for today lists earnings of

they are not paying for page impressions, but how does this work?
Surely some AdWords advertisers *are* paying for impressions if they opt
to do so. This feature is about three months old. In most cases those are
graphic banners that get paid for impressions.
Obviously not a big deal in terms of actual earnings, but it makes you
wonder.
Well, some advertisers think they need to make their image stick to the
Web surfer’s mind even if they don't click on the ad.
Another surprising thing, though much less so, is how each click on a
given page may be worth three cents one day and sixty cents another.
The mechanism is obvious, but it's still surprising to see.
On top of that, the CPC normally fluctuate during the day! You will
generally find that higher CPC are normally paid in the morning, and then
some advertisers "wash out" as the depth of their pocket for the day is
reached. That has a two-fold effect: there are fewer ads for your visitors
to click on and there's less competition, which lowers the CPC.
