Understand what this lesson solves
Strong ROAS is not enough. Calculate incremental spend, cash gap, inventory, and fulfillment first, then check PMax product and landing-page boundaries before a small scale step.
Verify your account, product data, and conversion signals, then choose Search, Shopping, or PMax and run your first controlled optimization cycle.
Lesson outline
- 1Run the four pre-budget questions first
- 2Split new customers, brand / non-brand, SKU, and marginal quality
- 3Choose one scale path
- 4Check PMax / Feed / SKU / Final URL / GTIN boundaries
- 5Use ROAS / Pricing tools to write profit and cash ceilings
- 6Write the observation window, frozen variables, and rollback line
- 7Leave copyable lesson notes and schedule the review
Public core framework
- Before increasing budget, ask whether the sample is enough, profit still clears the line, inventory / fulfillment can absorb demand, and the rollback line is written.
- Separate brand terms, remarketing, returning customers, non-brand new customers, priority SKUs, low-margin SKUs, search terms, CPA, CVR, AOV, and post-refund contribution profit.
