Which ad buying option is typically expensive and purchased for day-long exposure?

• A. CPC bidding
• B. CPM bidding
• C. CPA bidding
• D. Masthead

Answer: (D)

Masthead ads refer to premium, high-visibility placements that take over top homepage or app screen real estate. They’re sold as a fixed package for a defined period, often an entire day, which guarantees that the brand is seen continuously during that window. Because you’re securing exclusive prominence and broad, uninterrupted exposure, these units carry a premium price compared with other formats. The other options describe pricing models—cost per click, cost per thousand impressions, and cost per action—used across many placements, but they don’t inherently guarantee day-long exposure or premium homepage real estate. So, the option that is typically expensive and purchased for day-long exposure is the Masthead.
