Which advertising feature allows businesses to tailor spending based on the duration of a campaign?

The option that allows businesses to tailor spending based on the duration of a campaign is the Lifetime Budget feature. When selecting a Lifetime Budget, advertisers can set a fixed amount they are willing to spend over the lifespan of their campaign. This budget will be distributed by the advertising platform gradually to maximize performance based on the campaign schedule, which can be particularly useful for campaigns with specific start and end dates.

This contrasts with Daily Budget, which allocates a set amount of spending per day, limiting expenditure to only daily intervals and not allowing for flexibility across the entirety of the campaign duration. Campaign Budget Optimization focuses on managing budgets across multiple ad sets but does not inherently reflect the duration of a single campaign. Ad Scheduling allows businesses to specify times and days to show their ads but does not directly control the overall budget across the entire campaign timeframe. Therefore, the Lifetime Budget feature is uniquely designed to align with the total expenditure over a campaign's duration.
