This lesson helps you: How to run a first ecommerce ad: compare organic and paid traffic, then define one product, market, page path, and budget window.
Start here if you're new to this series. Then read: "CPM Analysis: Impression Cost and Traffic Quality".
This lesson helps you: How do you calculate CPM, and what counts as normal? Use a 20oz tumbler case to connect impression cost with placement, CTR, orders, and profit before scaling.
Best after "Independent Store Advertising Basics: Traffic Sources and the First Ad". Then continue with "CPC Analysis: Click Cost and Traffic Quality".
This lesson helps you: What did each ad click cost on average? That is CPC. Follow a travel-and-outdoor store's 20oz tumbler case to read click cost with landings, carts, orders, and profit.
Best after "CPM Analysis: Impression Cost and Traffic Quality". Then continue with "CTR Analysis: Click-Through Rate and Buying Intent".
This lesson helps you: After an ad is shown, how often does it bring a click? That is Click-Through Rate (CTR). Use a 7-day 20oz commuter tumbler case to read CTR with page views, carts, purchases, placement, and profit, then decide whether the ad attracts buying intent or curiosity.
Best after "CPC Analysis: Click Cost and Traffic Quality". Then continue with "CPA Analysis: Acquisition Cost and Profit Guardrails".
This lesson helps you: Fix market, time, ad slice, and observation window first. Then use the CPA profit guardrail to decide whether orders from one defined target action can cover contribution profit after the refund cutoff and carry the payback wait before moving budget.
Best after "CTR Analysis: Click-Through Rate and Buying Intent". Then continue with "ROAS Analysis: When High ROAS Does Not Justify Scaling".
This lesson helps you: High ROAS is not permission to scale. Fix the campaign scope, then separate platform, post-refund, and contribution-profit reads.
Best after "CPA Analysis: Acquisition Cost and Profit Guardrails". Then continue with "Ad Attribution: Reconcile Meta, Google, GA4, and Shopify".
This lesson helps you: Attribution is not one truth: use one 20oz tumbler order to see what Meta, Google, GA4, and Shopify can each explain before moving budget.
Best after "ROAS Analysis: When High ROAS Does Not Justify Scaling". Then continue with "Creative Fatigue Diagnosis: Creative, Page, or Audience?".
This lesson helps you: When ads weaken, use frequency, CTR, CPA, comments, stock, and profit to diagnose creative fatigue, separate audience, page, and offer issues, and choose refresh, repair, or pause.
Best after "Ad Attribution: Reconcile Meta, Google, GA4, and Shopify". Then continue with "Ad Budget Scaling: Sample, Profit, and Pacing".
This lesson helps you: Better ROAS does not automatically justify more budget. Check the sample, marginal profit, stock, support, and creative before testing a small step, holding, or rolling back.
Best after "Creative Fatigue Diagnosis: Creative, Page, or Audience?". Then continue with "Ad Account Structure: When to Consolidate and When to Split".
This lesson helps you: How to structure an ad account: separate brand, remarketing, prospecting, and testing, then choose a split, consolidation, or observation window.
Best after "Ad Budget Scaling: Sample, Profit, and Pacing". Then continue with "Creative Testing: High CTR but No Orders".
This lesson helps you: Do not call a high-CTR asset a winner yet. Test one variable at a time, then read clicks, checkout, purchases, and profit together.
Best after "Ad Account Structure: When to Consolidate and When to Split". Then continue with "Incrementality Testing: Which Orders Are Truly New?".
This lesson helps you: Attributed orders do not always mean new business. Compare a control group, log contamination, and read business results before keeping, reducing, or retesting spend.
Best used as the closing lesson after "Creative Testing: High CTR but No Orders".
