Understand what this lesson solves
High ROAS is not permission to scale. Fix the campaign scope, then separate platform, post-refund, and contribution-profit reads.
Learn to read CPM, CPC, CTR, CPA, ROAS, and attribution as one decision system, so you can tell whether to fix, pause, or scale spend.
Lesson outline
- 1Fix the campaign scope, then define value / spend
- 2First reconcile platform value to Shopify net sales
- 3Continue through refunds and variable costs
- 4Decide whether high ROAS can really scale
- 5Leave one ROAS review conclusion
Public core framework
- You do not need CPA first: name the market, timezone, time window, ad slice, target action, ad spend, currency, currently visible attribution setting, and refund cutoff. If you just finished CPA, carry that same scope forward.
- Do not write only platform ROAS. Record Google Ads / Meta value, Shopify net sales, transaction_id, order status, discount, cancellation, and payment status to see how far platform-attributed revenue differs from backend net sales.
- Deduct refunds, chargebacks, support compensation, COGS, fulfillment, payment fees, packaging, free shipping, and variable support cost from Shopify net sales. Calculate contribution before ads and contribution profit after ad spend.
