Which action does the CPA model typically charge advertisers for?

The CPA (Cost Per Action) model charges advertisers based on a specific action taken by a consumer after interacting with an advertisement. This action can encompass various outcomes, such as making a purchase, signing up for a newsletter, or completing a form. The primary focus of this model is to drive measurable results, ensuring that advertisers only pay when a consumer performs the desired action, making it a performance-based pricing structure.

The CPA model is advantageous for advertisers because it aligns their spending with tangible outcomes rather than just clicks or impressions. By charging for specific actions, this model incentivizes advertisers to optimize their campaigns for conversions, effectively maximizing their return on investment.

In contrast, charging for every ad impression served relates to brand visibility rather than direct consumer action, while charging for every click focuses on engagement rather than tangible outcomes. Charging for each video view, similarly, emphasizes exposure rather than the resulting interactions or commitments from the viewer. Therefore, the CPA model distinctly prioritizes actions that indicate a deeper level of consumer interest and engagement, establishing it as the correct choice.
