## Common Mistakes to Avoid

- Running 3 creatives per ad set — need 10+ for CBO to optimize - Killing ads too fast — give 48h + $30 spend minimum - No fatigue monitoring — creatives die at day 7–10 - Ignoring copy variants — hook matters as much as image - Not reallocating budget — winners need fuel fast

## FAQs

**How many variants per launch?** 20 is the sweet spot for Meta CBO; 5 for Google.

**What kill threshold?** CPA 2x target after $30 spend and 48h; be strict.

**Can AI write ad copy?** Yes — it's now 80% of Meta ad copy; human edits for brand voice.

**What about video creatives?** Use AI tools like Arcads or HeyGen for avatar videos; user-generated content still wins for many verticals.

**Should I automate budget scaling?** Yes above threshold ROAS — most tools allow auto-scale rules.

## Conclusion

Ad creative testing is where performance marketing is won in 2026. Automate variant generation, kill losers fast, scale winners aggressively — 40% ROAS lift is realistic within 90 days.
