Understand what this lesson solves

Basic full lesson

When ads weaken, do not replace creative first: use frequency, CTR, CPA, comments, and profit to separate fatigue from audience, page, and offer problems.

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

  1. 1Compare against the first three-to-five-day baseline first
  2. 2Check page, price, stock, and tracking counter-evidence
  3. 3Separate audience narrowing from creative promise decay
  4. 4Choose one refresh variable only
  5. 5Write the creative-refresh review conclusion

Public core framework

  • Record launch date, audience, budget, first three-to-five-day frequency, CTR, CPC, CPA, CVR, AOV, refunds, new-customer share, and contribution profit. Without a baseline, do not call fatigue from today's high frequency or high CPA alone.
  • If CTR holds but CVR falls and CPA rises, inspect the mobile first screen, page speed, price rules, discount, stock, shipping promise, checkout, UTM, and event firing. If any of these changed recently, do not make creative take the blame first.
  • If frequency rises mainly from retargeting, seed audience, or tight geography, inspect audience size, reach, new-customer share, placement, and exclusion rules first.
