Documentation / Testing and results

Watcher runs Google PageSpeed Insights–based lab tests on a schedule and on demand. This topic covers mobile versus desktop strategies, how to read scores and metrics, and how site API usage and quotas affect what you can run. Come here when a score looks odd, when you need both strategies for a key template, or when you are close to quota and need to prioritise. For CrUX gaps or failed runs, see Troubleshooting.
