Ad Set Budget Sharing

Ad set budget sharing allows you to share up to 20% of your daily budget with other ad sets to improve performance for campaigns not using a campaign budget. This allows you to control budgets for each ad set while adjusting up to 20% of your ad sets’ spend up or down in real time, depending on when more opportunities are available to improve your campaign’s overall performance.

With ad set budget sharing, you can:

• Maintain budget control at the ad set level and allow some flexibility with your budget.
• Lessen manual guesswork by automating some of your budget allocation based on performance in real time.
• Use different ad set schedules while still having flexibility across ad sets. Note: If your ad sets end and there is only one active ad set still running, ad set budget sharing will not be applied because there are no active ad sets to share budgets with.

There are several features you can use with budget sharing:

• Budget sharing can only be used for campaigns with a daily budget at this time.
• You can use budget sharing for all objectives within the auction.
• Budget sharing is compatible with multiple bid strategies (auto, manual, etc), however the bid strategy must be the same across all ad sets in the campaign.
• Ad set budget sharing will only affect new and duplicated campaigns. Existing campaigns will not be impacted.
• Ad set budget sharing is currently available during campaign creation and mid-flight. You may enable or disable at any time.

When to use ad set budget sharing

You can use budget sharing when you want want to increase conversions, while still maintaining control over majority of their budgets with partial automation, for example managing budget controls across

• Audiences, such as re-targeting and prospecting audiences
• Product or promotions, such as for sales or or time-based events
• Geographies, such as for brick and mortar locations
• Creative, such as to allow budget delivery across new and existing creatives

How ad set budget sharing is different from Advantage+ campaign budget

Ad set budget sharing allows you to control the majority of where your budget is delivered and can only be used with daily budgets. This is a partial automation product, where up to 20% of the budget is flexible with other ad sets in the same campaign and only when it is likely to find more opportunities.

Campaign budget allows you to leverage full automation and achieve the most efficient results because 100% of your budget is flexible and automatically allocated to find the best opportunities. With campaign budget, advertisers may specify minimum and maximum ad set spending limits.

How ad set budget sharing works with your daily budget

When you use budget sharing with your campaign, each ad set will not exceed 20% of its weekly budget, regardless of whether other ad sets are willing to share up to 20% of their budget. The only case when it may exceed 20% is if the ad set cannot reach delivery for the allocated budget, such as for audience that is too small. The maximum amount an ad set can spend daily is up to 20% on top of the daily flexibility value (75%).

For example, this can look like:

Parameters

Return Type

{is_adset_budget_sharing_enabled: True }

Error codes

Creating

You can enable ad set budget sharing during the campaign creation by passing in True to the is_adset_budget_sharing_enabled field. Starting with v24.0+, you must pass either “True” or “False" to this field if you plan on setting a budget at the adset level, meaning you are not passing in the campaign budget during the campaign creation. Passing in “True” to that field will turn on the optimization. You do not need to pass this field if you are using a campaign budget, meaning you set either daily_budget or lifetime_budget at the campaign level.

Example

curl -X POST \
  -F 'name="My campaign"' \
  -F 'objective="OUTCOME_TRAFFIC"' \
  -F 'status="PAUSED"' \
  -F 'is_adset_budget_sharing_enabled="True"' \
  -F 'special_ad_categories=[]' \
