It is commonly used in brand awareness and reach-focused campaigns, where visibility matters more than immediate clicks or actions. A high CPM may reflect premium placement, a highly targeted audience, or seasonal competition, such as holiday-season retail campaigns. Conversely, low CPMs often occur on broad-reach platforms or content placements where competition is lighter. For example, a global apparel brand may run campaigns at a $5–$20 CPM to build top-of-funnel awareness, while niche B2B campaigns might see higher CPMs due to specialized targeting. CPM helps advertisers gauge cost efficiency for exposure-focused campaigns. ### Explore more Glossary terms ##### Customer Journey Mapping Customer Journey Mapping visualizes how customers move through stages like awareness, consideration, purchase, onboarding, and loyalty.
