What is cpm?

What does cpm mean? Lets get to the meaning of cost per mille word by word.

Cost you know already, it means value or amount in some form of currency.

The word mille comes from latin and it means thousand or one thousand. People often confuse this Mille with Mile. Both of these words different.

Mile is used to measure length. 1 Mile is 1609 meters or 5280 feet but we are not interested in that.

Ok, so whole mean is cost per one thousand. But what one thousand?

It can be one thousand ad views or one thousand ad impressions.

Almost all of the times impressions are confused with views.

A page or an advertisement is considered viewed if user actually sees the advertisement, when ad comes in focus on the page. On the other hand an impression is counted when a page or an advertisement is loaded on the page. It doesn't matter it user actually scrolls and see the ad, an impression is still counted.
