FAQ
What is an "impression"?
One instance of an ad being displayed to a user, regardless of whether it was clicked.
Why measure cost per 1,000 rather than per single impression?
A single impression costs a tiny fraction of a currency unit, so the industry standard expresses cost per thousand (mille) for readable numbers.
How does CPM relate to CPC?
CPM measures cost of reach/visibility; CPC measures cost of an actual click — a campaign can have a great CPM but a poor CPC if the ad doesn't drive clicks.
