Last 30 days speed score out of 100 · higher is faster

From Google's test on a simulated mid-range phone. Lower is better.

Scripts from apps and services, ranked by how long they keep the phone busy on Google's test.

Google's suggestions for this page, biggest first. This app only reports; you or your developer decide what to change.

From Google's Chrome User Experience Report: real visits to your store from Chrome on phones.

How this works

The test: Google PageSpeed Insights loads each page on a simulated mid-range phone with a slowish mobile connection. It is the same test as pagespeed.web.dev.
Two runs, middle result: every page is tested twice and we show the median, because a single test can swing 5 to 10 points with nothing changed.
Score colours follow Google: 90 to 100 green (good), 50 to 89 orange (needs work), 0 to 49 red (poor).
Every day each page is checked once in the early morning (your store's time zone). "Check now" adds up to 3 extra checks a day.
Real visitors show how the store actually felt to people over 28 days. Google only has this for stores with enough Chrome visitors.
Alerts: an email when the home page score drops 10 points or more below its 7-day middle value, or the main content shows 1 second or more later. At most one a day.
Read-only: this app never changes your theme, apps or store. It reads your product and collection addresses only to pick pages to test.
