Contoso Investments are bidding for individual display impressions in an action. This is an example of which sales model?

The programmatic sales model involves automated, real-time bidding for individual ad impressions, often through real-time bidding (RTB) exchanges. This aligns with Contoso Investments bidding for individual display impressions in an auction. The search advertising sales model focuses on ads displayed on search engine results pages, not display impressions. The cost per thousand impressions (CPM) sales model is a pricing structure, not a sales model describing how impressions are acquired. The guaranteed sales model involves pre-negotiated, fixed-price agreements for a set number of impressions, which contrasts with bidding in an auction for individual impressions.
