My product is profitable at $100/day. Every time I increase the budget, ROAS drops. Why?

The wall every profitable operator hits, often causes them to stop scaling entirely

This is the budget scaling wall, and it happens for specific technical reasons that are fixable once you understand them:

Budget doubling triggers a new learning phase. When you increase your budget by more than 20–30% at once, Meta's algorithm treats it like a new campaign and re-enters learning mode. Your previously-optimized delivery model resets. ROAS drops during the learning reset, then recovers, but operators panic and scale back before it recovers.
Your audience is getting saturated at higher spend. At $100/day you're reaching your best buyers efficiently. At $500/day, you've exhausted the highest-intent portion of your audience and you're reaching progressively lower-intent people at higher CPMs.
Your creative pool isn't big enough for higher budgets. A single winning creative running at $500/day will burn out within days. Scale requires a constant creative supply, not just a budget increase.

Tactical FixUse the Surf Scaling protocol from Module 17: check performance every 2–4 hours. If ROAS is 100%+ above your KPI target, double the budget. If ROAS is 20–50% above KPI, increase 20–30%. If ROAS is at KPI, hold. This active method allows doubling when performance clearly justifies it, while the 20–30% rule applies when you're scaling cautiously on a borderline-profitable campaign. Never scale budget without simultaneously launching new creatives, creative supply is the rate-limiting factor at higher spend, not budget.
