What is cost per mile?
Cost per thousand/Cost per mile is a kind of prototype of payment for advertising on the Internet. Advertiser gives money for every thousand impressions with the use of advertising materials, commonly banners. It is paid to affiliates, who try to promote advertiser’s product, service or site.
Cost per thousand CPT (CPT) is also called as Cost Per Mille CPM because word M also means number 1000.
It denotes the cost advertisers incur for every thousand impressions (views) their advertisement receives. The term “mile” is derived from the Latin “mille,” meaning a thousand, thus CPM signifies the cost for each set of a thousand impressions.

Understanding CPM in Affiliate Marketing
In affiliate marketing, CPM is a pricing model where advertisers compensate publishers (affiliates) for every thousand times their ad is displayed on the affiliate’s platform, such as a website or an app. This model stands in contrast to others like Cost Per Click (CPC) or Cost Per Acquisition (CPA), where payments are contingent on user interactions or conversions.
How CPM Works
The CPM model operates on a straightforward principle. Advertisers agree on a predetermined price for every 1,000 views of their ad. For instance, if an advertiser sets a CPM rate of $5, they pay $5 for every 1,000 impressions their ad garners. This model is particularly effective for brand awareness campaigns, where the objective is widespread visibility rather than direct user engagement.
Calculating CPM
The formula to compute CPM is:
CPM = Total Cost of Campaign / Total Impressions * 1,000
For example, if an advertiser expends $500 on a campaign that attracts 200,000 impressions, the CPM would be:
CPM = $500 / 200,000 * 1,000 = $2.50
This calculation indicates the advertiser pays $2.50 for every thousand impressions.

CPM vs. Other Payment Models
- CPM (Cost Per Mille): Payment is based on the number of ad impressions, ideal for brand visibility campaigns.
- CPC (Cost Per Click): Payment occurs each time an ad is clicked, focusing on driving traffic.
- CPA (Cost Per Action): Payment happens only when a specific action is taken, such as a sale or sign-up, emphasizing conversions.
Factors Influencing CPM Rates

- Ad Placement and Visibility: Premium placements (e.g., above the fold) command higher CPMs.
- Audience Demographics: Niches with high-value audiences, such as luxury markets, often have higher CPMs.

On the other hand, the average CPM for Google search ads is around $38, whereas for Google display ads it is around $3.
