Scaling Meta Ads means increasing spend while maintaining return. The safest approach is the 20% rule: increase budget by no more than 20% every 3-4 days. Most accounts hit a ROAS cliff at 2-3x original budget.
Key Takeaways
Increase daily budget max 20% every 3-4 days. $100/day goes to $120, then $144, then $173. Jumps over 20% reset learning phase, causing 30-50% CPA spikes taking 3-5 days to recover.
Scale when: CPA below target 5+ days, frequency under 2.0, CTR stable/rising. Hold when: frequency above 2.5, CPA rising 3+ days, or creatives recently changed.
At 2-3x budget, Meta serves colder users. Counter with horizontal scaling: parallel campaigns with new lookalikes, interests, or geos. Rotate 3-5 new creatives weekly.
