On which level of a Reddit campaign is the targeting set?

Targeting is set at the Ad Group level on Reddit campaigns. This allows advertisers to create multiple ad groups within a single campaign, each with its own distinct targeting parameters (e.g., interests, communities, demographics). This granular control enables A/B testing of different audience segments and more precise optimization of ad spend. The Campaign level defines the overall objective and budget, not specific targeting. The Ad level focuses on the creative content and destination URL. The Objective level defines the campaign's primary goal, such as traffic or conversions, but doesn't specify the audience.
