When it comes to launching your retail media ad business, you’ll need to understand and select the right pricing model for your ad product. This decision influences how billing events — like impressions, clicks, and conversions — are monetized. It is a critical decision because each model carries varying risks for both publishers and advertisers (see Figure 1).

Overview of ad pricing models

Your choice in pricing model should align with what you intend to sell, such as time slots, impressions, clicks, and conversions. This decision is inevitably a vertical-specific calculation. On-demand delivery platforms favor different economics than a general retailer or specialized marketplace.

As you consider each ad model, think about your own advertisers and their most pressing needs. Below we cover a few of the most common options, as well as a table overview with the best features and tradeoffs of each approach by category (see Figure 2)

Cost per time

Similar to traditional brand awareness tactics like out-of-home advertising, cost per time (CPT) sells your banner ad inventory based on time slots and dates. While this approach limits potential targeting or performance metrics, it can work well for advertisers looking to engage consumers during a specific time of day or monthly period (e.g. minority-owned restaurants during Black History Month).

Cost per mille

A staple of display advertising, cost per mille (CPM) charges for inventory based on every 1,000 impressions of an ad. Since this model doesn’t require conversion tracking, CPM typically caters to brand advertising goals — though, performance campaigns are dedicating more budgets here if a platform can provide access to hard-to-reach or high-value audiences.


Cost per click

Most performance ads run on a cost-per-click (CPC) model, where advertisers pay not per impression but only for actual consumer interactions. This approach helps lower risk for advertisers, while giving platforms a chance to align budgets with campaign performance and optimized user experiences. 

In the US market, Amazon has used a CPC model to drive significant high-margin revenues, matching strong ad performance with better relevancy for consumers.


Pay per order

Pay-per-order (PPO), also called cost-per-sale (CPS), is a newer model that charges advertisers only after a converted purchase occurs. This approach relies on sufficient demand from high-conversion sellers, and works best for defined commerce windows (e.g. delivery, travel) as well as long-tail e-commerce sellers, for whom there are no upfront costs. 

Leading delivery platforms, such as DoorDash in the US or Yogiyo in South Korea, use the PPO model to drive high seller adoption rates and clear value to advertisers. 

Success in the PPO model depends on scale, as these ad markets can generate lower revenues than CPC, and rates are harder to raise once established. If CPC is already available as a pricing model, it can be challenging to introduce PPO in the same platform without complicating auction dynamics.
