Cost Per Mile CPM

What is Cost Per Mille (CPM)?

Cost Per Mille, frequently abbreviated as CPM, is the price an advertiser pays for one thousand impressions for their digital advertisement. In essence, it's a benchmarking tool that helps advertisers measure how much they are spending to have their ad seen by thousands of potential customers

Some of its salient features include

- Understanding CPM is critical for advertisers aiming to optimize their ad spend and maximize reach.

The Calculations Behind CPM

Calculating Cost Per Mille is simple. You divide the total cost of the advertising campaign by the number of impressions ( in thousands). For instance, if a campaign costs $200 and garners 50,000 impressions, the CPM would be $4.

CPM = Total Ad Spend / total Impressions served in thousands 

Important note

An impression is different from a view. Today, an impression is counted when the ad is delivered to the user's device. The ads need not be viewed to be qualified as an impression. 

An impression becomes a view when at least 50% of the ad is seen for at least 1 second. So, CPM is different from CPV(Cost per View) or Cost per viewable impression as it is generally called.

In this case, Cost per mile plays an important role in comparing the normalized the return on investment(ROI) calculation.
