Who This Is For / When to Use
This guide is for users who want to test and optimize campaigns by running multiple ad sets under one campaign.
Use this article when:
You want to A/B test different audiences
You need to compare creatives or placements
You want to scale campaigns while maintaining structure
You are optimizing performance across multiple variables
What Are Multiple Ad Sets
Multiple ad sets allow you to test different variables within the same campaign while keeping budgets, goals, and reporting organized.
Each campaign can contain up to 10 ad sets, and each ad set can target a different audience, creative setup, or placement strategy.
This structure enables controlled testing without launching multiple campaigns.
How to Create a Campaign with Multiple Ad Sets
Step 1: Launch Your Campaign
Start by launching your campaign as usual.
Go to the Advertise tab
Create and launch a new campaign
The campaign will start with one default ad set
Step 2: Add a New Ad Set
After the campaign is live, you can duplicate the existing ad set.
Open the campaign
Click View Results
At the top of the ad set section, click Add New Ad Set
The system duplicates the existing ad set automatically
Step 3: Customize Each Ad Set
Each ad set can now be customized independently.
You can modify one variable at a time to run controlled tests.
What You Can Test with Multiple Ad Sets
Audience Targeting Tests
Keep the creative the same and change only the audience.
Common audience tests include:
Interest-based targeting
Lookalike audiences
Retargeting audiences
Broad or Open AI targeting
This helps identify which audience converts best.
Creative Tests
Use different creatives across ad sets.
Examples:
Image ads vs. video ads
Carousel vs. single image
Static vs. animated creatives
Each ad set should contain only one creative type for clarity.
Landing Page Tests
Send traffic to different landing pages.
Use this to compare:
Conversion rates
Page engagement
Lead or purchase performance
This isolates landing page impact on results.
Placement Tests
Test where ads appear.
Examples:
Vertical placements (Facebook Reels, Instagram Reels)
Standard feed placements
Platform-specific placements
This helps identify the most efficient placement strategy.
How to Edit an Ad Set
Ad sets can be edited at any time after creation.
Select the ad set tab you want to edit
Update targeting, creative, destination, or budget
Save changes
Each ad set updates independently without affecting others.
How to View Performance by Ad Set
Performance can be reviewed at both campaign and ad set levels.
To see ad set performance:
Open More Insights
View metrics broken down by Campaign and Ad Set
Compare spend, clicks, CTR, CPC, reach, and CPM
Select an individual ad set to make optimizations
This allows data-driven decisions on which ad sets to scale or pause.
Best Practices for Multiple Ad Sets
Change one variable per ad set
Allow enough time for data collection
Avoid frequent edits during testing
Pause underperforming ad sets gradually
Scale winning ad sets by increasing budget incrementally
Common Issues and Fixes
Too many variables changed at once
This makes results unclear.
Fix:
Limit each ad set to one test variable.
One ad set spends most of the budget
This can happen due to delivery optimization.
Fix:
Use equal budgets initially or monitor delivery closely.
Results look similar across ad sets
This may indicate insufficient differentiation.
Fix:
Increase contrast between audiences or creatives.
