About the result

This is a point-in-time lab test using Google's mobile Lighthouse data, run through our server so the check doesn't fail on you silently. Total Blocking Time is a lab indicator; it is not the field responsiveness metric INP. A real-user Core Web Vitals assessment requires suitable field data.
