| Routing reliability | Broken app/web fallbacks cause traffic loss during peak campaign periods. | Test installed-app, non-installed-app, and in-app-browser behavior across iOS and Android. |
| Attribution integrity | Dropped UTM parameters make paid and creator traffic reporting unreliable. | Verify `utm_*` and partner click IDs survive every redirect hop to final URL. |
| Publishing operations | Slow update workflows delay launches and increase manual error risk. | Measure how quickly non-engineers can update destinations and titles safely. |
| Troubleshooting visibility | Without link-level evidence, teams cannot explain sudden performance drops. | Require timestamped click logs and redirect traces for incident review. |
