Run Google PageSpeed Insights on any page and get the results in plain language, with the slowest problems at the top and what to do about each.
PageSpeed in Visiblio runs Google PageSpeed Insights for a page on mobile and desktop and turns the Lighthouse report into a short, readable list. You see the Core Web Vitals, the real-world data Google has for the page when it exists, and the opportunities ranked by how much time they could save.
Instead of a wall of technical audit names, each item is explained in our own words: what is slow, why it matters and which fix is worth your developer's time.
Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift with a clear good, needs work or poor mark.
See Lighthouse test results and, when Google has them, the data from real visitors.
Every opportunity explains what it means and what to ask your developer to do.
Switch between the two, because the results are often very different.
The same check appears inside the page profile of the Technical SEO Crawler.
Scores, timings and the biggest opportunities are shown in order, with the size of the saving, so the first fix is obvious.
See the three Core Web Vitals for the page and what each one measures, so you can talk about them with developers and clients.
Total page weight, the largest files and unused code are listed, so you know whether images, scripts or fonts are the problem.
Paste the page you want to test and choose mobile or desktop.
Visiblio asks Google PageSpeed Insights and shows the answer as soon as it is ready.
Work down the list, then run the test again to see the improvement.
Explain page speed problems to clients and developers in plain language.

A page speed test loads a page in a controlled browser, measures how quickly content appears and becomes usable, and reports what slows it down. Visiblio uses Google PageSpeed Insights, which also shows real-visitor data when it exists.
Core Web Vitals are three measurements Google uses to judge page experience: how fast the main content loads, how quickly the page responds to a click or tap, and how much the layout shifts while loading.
Mobile tests use a slower connection and a less powerful device, so the same page usually scores lower on mobile. Check both, and treat mobile as the priority for most websites.
Page experience is one of many signals Google uses, and it matters most when pages are very slow. Faster pages also keep visitors, which helps conversions regardless of rankings.
