{  What you can set  }

Options and limits

Everything here is per site or per environment, from the panel, with every change in the activity log.

What is tested
The live home page, on the site’s main domain. Preview addresses are not tested.
How often
About once a day, on mobile and on desktop.
Run now
Up to twice an hour per site. The daily test does not count towards it.
Metrics
Performance score, LCP, CLS, INP, TBT, FCP, Speed Index and TTFB.
Real visitors
INP comes from Chrome’s real-visitor data, once Google has enough of it.
History
90 days of scores, as a chart and as a list of every run.
Alerts
A 15-point drop in a week, a Core Web Vital turning poor, or three failed tests in a row.
Maintenance
Sites in maintenance mode are skipped until it is turned off.

Questions about pagespeed

No. Google runs each test from its own servers, once a day per device type. To the site it is one visitor loading the home page.

The home page of each live site, on its main domain. Other domains redirect to it, so they would measure the same page. Password-protected preview addresses are not tested.

INP is measured from real visitors in Chrome, not in the test. Google only reports it once a site has enough traffic. LCP and CLS come from the test itself.
