CPM

CPM stands for cost per mille, a metric used in digital advertising that represents the cost of one thousand advertisement impressions. It allows advertisers to compare the relative cost of campaigns across different platforms and formats by standardizing pricing to a per-thousand-impression basis.

Context and Usage

CPM is primarily used in digital advertising campaigns where the goal is brand awareness and reach rather than direct response actions. It is commonly employed by advertisers, publishers, and advertising agencies when purchasing display ads, video ads, and social media placements. The metric is particularly prevalent in programmatic advertising and real-time bidding environments.

Common Challenges

Common misunderstandings include conflating CPM with actual user engagement or conversion rates, as it only measures exposure cost. Low CPM rates sometimes correlate with lower ad quality or less valuable inventory, potentially impacting campaign effectiveness. Ad fraud and invalid traffic can artificially inflate impression counts without delivering actual audience value.
