How the test works
We run one Google Lighthouse test with the mobile preset (simulated slow 4G and a slower phone CPU). Scores move a few points between runs, and Google PageSpeed Insights may show slightly different numbers because it runs from Google's servers. Real-visitor data in Search Console can differ again.
The numbers that matter for Google's Core Web Vitals: LCP under 2.5 s, CLS under 0.1. TBT is the lab stand-in for how responsive the page feels.
We only test public websites, and we don't store results beyond a short cache. Want it fixed? See Speed Fix pricing.
