1. testing structure
An efficient testing structure is key to optimizing your campaigns. The setup that shows up most often among the top performers in the database is:
- Campaign: 1 objective (e.g., conversions)
- Ad set: 3-5 different audiences
- Ads: 3-5 creatives per ad set
Decision rule: If you’re not getting results, test new audiences or new creatives.
2. creative matrix
To avoid burning money testing creatives, use the hook × format × proof matrix:
- Hooks: 3 to 5 main hooks (e.g., pain point, solution)
- Formats: 3 formats (e.g., image, video, carousel)
- Proof: 2-3 types of social proof (e.g., testimonials, case studies)
Decision spreadsheet: Track the performance of each combination and adjust as needed.
3. CBO or ABO?
As campaigns evolve, choosing between CBO (Campaign Budget Optimization) and ABO (Ad Set Budget Optimization) becomes crucial.
- CBO: Use it when you have 3 to 5 ad sets with distinct audiences.
- ABO: Use it when you need tighter control over spend per ad set.
Switching rule: If CBO isn’t performing well after 3 days, consider switching to ABO.
4. advantage+ shopping
Advantage+ Shopping is a powerful tool, but it should be used with caution.
- Tip: Use Advantage+ campaigns to test new products or audiences, but keep separate campaigns for performance tracking.
Decision rule: If performance drops, pause Advantage+ and analyze the data in detail.
5. learning phase
Understanding the learning phase is essential to avoid frustration.
- What actually resets it: Significant changes to creatives or audiences.
- Myth: The phase only resets when you pause and restart the campaign.
Tip: Keep your campaigns stable during the learning phase to maximize performance.
6. effective retargeting
For retargeting that actually converts with COD, consider:
- Retargeting windows: 7, 14, and 30 days.
- Offers: Discounts or free shipping can increase your conversion rate.
- Frequency: Limit frequency to 2-3 impressions per day.
Decision rule: If your conversion rate is low, adjust the retargeting window or the offer.
7. lookalike: does it still work?
Lookalike can still be effective, especially when you use the right seed audiences:
- Seeds: Use lists of customers who purchased in the last 30 days or people who completed a lead form.
Tip: Test different percentages (1% to 10%) to find the ideal audience.
8. pixel + CAPI
Integrating Pixel and CAPI (Conversions API) without a developer is possible. Follow this checklist:
- Key events: Install purchase, product view, and add-to-cart events.
- Deduplication: Use transaction IDs to avoid duplicate counts.
Decision rule: If there’s no data in Pixel, check the CAPI integration.
9. final checklist
- Structure your campaigns based on the testing matrix.
- Use a variety of creatives (hook, format, proof).
- Choose between CBO and ABO based on results.

- Keep things stable during the learning phase.
- Run retargeting with effective windows and offers.
