At which level can you edit the ad set's budget and schedule?

The budget and schedule for an ad set are specifically defined at the ad set level. This allows for granular control over how much you want to spend and when the ads will run. By adjusting the budget and schedule at this level, advertisers can optimize their campaigns according to the performance of individual ad sets, which might target different audiences or objectives.

Choosing the ad set level for these adjustments is essential because it lets advertisers allocate their budget and schedule based on specific target demographics or behaviors, ensuring a more focused and effective advertising strategy. The campaign level, by contrast, sets overarching objectives and strategies for all ad sets within it but does not allow for the same level of detailed financial and timing control. The ad level is typically focused on creative elements and messaging, rather than budget or scheduling. There is no recognized "group level" in the context of Facebook advertising, which further clarifies that the correct setting for budget and scheduling adjustments is indeed at the ad set level.
