# Change sub-campaign budget allocation

By default, Advigator automatically distributes the budget you set at the campaign group level across sub-campaigns, such as Sponsored Products, Display, Brand, and Video. This allocation is based on recent spend trends to ensure no campaign type runs out of budget too early or leaves budget unused by the end of the day.

We don’t adjust budgets based on ACoS because Advigator uses click bids to optimize spend allocation according to performance.

If you prefer to assign fixed budget percentages to each sub-campaign, you can do that here. Just make sure the total adds up to 100%.
