Diagnostic answer
Why did my Meta ROAS drop?
A ROAS decline can reflect revenue measurement, conversion delay, auction cost, conversion rate, creative or the offer. First match the account, dates, currency and attribution definition; then separate the numerator from the denominator before changing campaigns.

What to check, in order
- Compare complete, comparable periods. Check whether purchase value fell, spend rose, or both changed.
- Reconcile orders and tracking. Missing events, refunds, timing or a different attribution window can change reported ROAS without the same change in underlying sales.
- Inspect creative, audience exposure, placements, landing pages and inventory. Keep learning and conversion delay in view before judging recent edits.
- Choose a small, evidence-backed change and record the baseline. A before/after difference alone does not establish that the change caused improvement.
A worked example
Illustrative example, not a customer result. Illustrative arithmetic: $8,000 of attributed purchase value ÷ $2,000 spend is 4×. If the reported value falls to $6,000 at the same spend, the ratio is 3×. That calculation identifies what changed, not why.
What this answer cannot establish
This guide cannot diagnose an account without its evidence, establish causal lift or guarantee savings. A valid zero is different from missing data. When inputs are incomplete, check permissions, collection status and the observation window before changing the account.
