Set your actual target campaign budget.
Make sure your ad group budget covers at least 50* target CPA when running App Install.
Ensure your ad group budget covers at least 20* target CPA while running either AEO or Conversions.
Ensure at least 3~5 unique and active ad groups per campaign, and 2-3 unique creatives per group.
Note: CBO does not function when there is only 1 ad active group in the campaign.
Wait for at least one day and 50 conversions before making new adjustments.
When adjusting your budget, try to control each adjustment within 30% of the current daily budget.
Note: TikTok Ads Manager requires all ad groups within a CBO campaign to apply the same optimization goal.
The Split Test feature on TikTok Ads Manager does not support CBO campaigns. We suggest you conduct manual A/B testing by creating 2 campaigns if needed.
