What to do after checking the week-over-week ROAS trend?
Identify what moved your ROAS
When week-over-week ROAS shifts, check Frequency (exposure), CTR (engagement), and Purchase CVR (conversion). CTR↑ with steady Frequency suggests creative or audience improvement; Frequency↑ with CTR↓ points to fatigue; CVR↓ with CTR stable suggests checkout or offer friction. Note the percent change and likely driver.
Plan one focused weekly test
Change one lever at a time. Keep audience, offer, and landing page constant; refresh only creative or messaging if engagement is the issue, or address checkout/offer if CVR fell. Use next week’s ROAS, CTR, and Purchase CVR to judge impact before repeating.
Decide with a simple weekly rule
Make decisions weekly. Look for two consecutive weeks moving the same way before scaling or slowing budgets. If ROAS dips, hold spend steady, review Frequency, CTR, and Purchase CVR, then schedule the next isolated test for the following week.
