Frequently asked questions
How does the speed comparison work?
Both sites are tested at the same time with Google PageSpeed Insights, which loads each page in a real browser on a simulated phone or desktop. You see Google's scores, Core Web Vitals and real-visitor data side by side.
Why compare with a competitor?
Speed is relative. If your competitors load in 1.5 seconds and you take 4, visitors notice, and Google uses page experience as a ranking signal. Comparing shows exactly where you are behind.
Which number matters most?
Largest Contentful Paint (LCP): how long until the main content appears. Under 2.5 seconds is good. Total Blocking Time and Cumulative Layout Shift matter for how smooth the page feels.
Why do results change between tests?
Network conditions and server load vary from moment to moment, so scores can move by a few points. Results are cached for an hour; compare again later for a fresh test.
