Should I use Advantage+ Audience or interests/lookalikes?

Advantage+ Audience is Meta's automated targeting that uses your inputs as suggestions and expands beyond them when the algorithm finds better conversion opportunities. For most accounts with clean conversion history, it outperforms manual interest and lookalike targeting.

This issue is common among Meta advertisers and usually indicates a structural or optimization problem that can be resolved with the right approach. Understanding the mechanism behind the problem is the first step to fixing it.

This problem typically stems from one or more of the following:

• Check monthly conversion volume (below 50 limits expansion signal)
• Check pixel and CAPI Event Match Quality (below 5 degrades automation)
• Assess ICP size: above 100k people suits expansion, below 5k needs manual

Follow these steps to identify the root cause:

1. Check monthly conversion volume (below 50 limits expansion signal)
2. Check pixel and CAPI Event Match Quality (below 5 degrades automation)
3. Assess ICP size: above 100k people suits expansion, below 5k needs manual
4. For B2B with narrow ICP: use manual targeting with precise filters
5. To test: run both in parallel for 14 days, compare CPA not CTR

Once you've identified the cause, apply these fixes:

1. Start by identifying the root cause using the diagnostic checklist above
2. Make one change at a time and wait 24-48 hours to see results
3. Document what you changed and the outcome for future reference
4. If the issue persists, consider reaching out to Meta support with specific details
