Unmeasured means there is not enough evidence to decide. How these checks work
Start using WebSpeed
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.

Status or result of a measurement started with measure_site. While running, returns the queue position or progress. When done, returns the verified comparison and what else slows the page down. Quote numbers only from this result and keep its wording about estimates; if it says there is nothing to judge, do not invent numbers.
DiscoveredStart a real PageSpeed Insights measurement of a web page: the original site vs. its copy accelerated by WebSpeed Fast (mobile and desktop). Returns an audit_id immediately; the run takes 2–5 minutes, and get_measurement reads it when the user asks. If the page was measured before, its full result is returned at once. Results are published as a report page on webspeed.pro. Use when the user asks why a site is slow, how fast it is, or what can be sped up.
