FAQ
Website Speed Checker questions
Where do the results come from?
From Google PageSpeed Insights, which runs a Lighthouse audit on the page. Scores match what Google reports for the same page.
Which pages can I test?
Any page that is publicly reachable. Pages behind a login, a password or a private network can’t be tested.
Why did my score change between tests?
Lab tests vary a little with network and server conditions. Look at the trend across several tests rather than one number.
Can Xpertech fix the issues for us?
Yes. Our Web Development Lab can carry out the work and re-test to confirm the improvement.
