CPM (Cost Per Mille)

Technical definition

The cost an advertiser pays per thousand impressions of their ad.

The ADLINGO translation

The base unit of digital media pricing. A $10 CPM means you pay $10 for every thousand times your ad is served. Simple enough. The complexity is in what counts as a served impression, whether it was viewable, and whether a human saw it. The CPM is just the price; the value behind it varies considerably.
