leadegroot,
will all due respect, 3 impressions and 1 cent is noting to be very confused about.

I probably havent been clear (I should know better than to post a question at this time of night! :) )
I understand the idea of site targetting - rather than ppc, pay-per-view, with a much smaller payment.
What I can't figure out is why I am seeing *only* 3 impressions on site targetting... and then it stops.
Surely 3 impressions isn't enough for an advertiser to determine that the quality of response isn't sufficient and stop the program. (I can't think of any other reason to pull a campaign after a big spend of 1 cent)
And its happened more than once, on more than one site.

I haven't looked at the adwords side for site targetting (what was that adwords login... ummm... ;)) but does it even allow for such a low number of impressions? What would be the point?
I'm wondering if its actually a glitch, and I havent had any real site impressions!

Yes you had real site impressions, but the CPM ads are only shown when they'll make you more money than a CPC ad in the same place. On my site the CPM ads account for under 5% of impressions though.

.....so perhaps they only appear briefly when the ppc ads drop out (run out of funding, whatever).
OK, that makes some sense - my niches are pretty good [1] and the pricing never seems to drop.
Either the advertiser sees they arent ever showing up and withdraws them after a bit, or leaves it there but I virtually *never* see it.
That would cover it. OK, I'm officially un-confused :)

[1] no, of course I'm not going to tell you :-P

Possibly the advertiser selected a number of sites to target, set their bid, and looks at the total number of impressions they are getting. If they don't get enough overall, they might adjust upwards, but they wouldn't adjust for just one site. Just a theory.
