CPM, also known as Cost per Mille, is a key term in Affiliate Marketing that refers to the cost for 1,000 ad impressions. The price for an ad is calculated based on the number of views, not clicks or purchases. This billing model is especially popular in campaigns focused on brand awareness and reach, where the frequency of ad displays is the priority.

The calculation is straightforward: the Advertiser pays a set amount for every 1,000 impressions of their ad. This model offers companies a transparent cost structure and allows precise budget planning. In Affiliate Marketing, CPM helps measure the success of ad campaigns based on views and to generate targeted reach.

Alongside other billing models like Cost per Click or Cost per Acquisition, CPM is particularly effective when the goal is to visually reach as many potential customers as possible. It gives Advertisers the chance to increase their target audience's attention through efficient placement, strengthening brand identity.

In summary, CPM (Cost per Mille) is a valuable billing model in Affiliate Marketing that charges based on ad impressions. It helps create visibility and boost brand awareness, which is crucial in today’s dynamic online marketing world.
