Scaling is a decision about economics, signal and operational readiness. The same budget change can behave differently across products and accounts.
- Increasing spend without a review boundary. Define the change, evidence window, conversion delay and stop condition. A twenty-percent step can be a team's planning heuristic; it is not a universal platform limit or a guarantee against volatility.
- Treating the catalog as one average. Inspect valid product groups, contribution and conversion quality. Do not infer profitable products from attributed revenue alone.
- Ignoring the destination. Check that the page answers the ad's promise and that the offer works after delivery, refunds and acquisition cost.
- Reading attribution as incrementality. Brand, non-brand and remarketing need explicit definitions; their labels do not identify which orders the ads caused.
- Optimizing a ratio without the business model. $10K spend at 10× ROAS implies $100K attributed revenue; $80K at 4× implies $320K. The second has more attributed revenue and $70K more ad cost. Which produces more contribution depends on margin, delivery and other costs.
Choose the next change from the actual constraint. Retain the baseline, work applied and decision rule so an apparent improvement can be checked.
