What best defines the campaign duration?

• A. The length of time the campaign runs
• B. The total budget allocated to the campaign
• C. The target audience size for the campaign
• D. The number of channels used in the campaign

Answer: (C)

Campaign duration is defined by the time window during which the campaign is active—the start date to the end date. This time period sets how long the ads run, how often they’re shown, and how you pace your activities. The total budget matters, but it governs how much you can spend within that window, not the length of time itself. The target audience size describes who you’re trying to reach, which affects reach and effectiveness, not how long the campaign lasts. The number of channels used affects where the ads appear, not the duration of the campaign.
