Troubleshooting

• No events arriving. Add ?roasdebug=1 to any URL and check the console. The usual cause is a missing or mistyped data-site.
• Sales show as unattributed. The checkout is dropping the visitor id. Pass vid on the Conversions API call, and read First-party delivery.
• ROAS looks too low. Spend is connected but revenue is not, or your attribution window is shorter than your real sales cycle.
• Spend is stale. The sync runs hourly and re-pulls a three day window, because platforms restate spend for up to 72 hours.
• Numbers moved after the fact. Late touchpoints and identity merges recompute hourly. Closed days are final; today is still settling.
