What Is PageSpeed Insights?
PageSpeed Insights is Google's free tool for measuring a page's speed and user experience. Just enter an address: the tool examines the page for both mobile and desktop and presents the results with two kinds of data.
Field data comes from the experience of Chrome users who actually visited the page over the last 28 days (the Chrome UX Report). This is where the Core Web Vitals are measured: LCP shows how long the largest piece of content takes to appear, INP how quickly the page responds to taps and clicks, and CLS how much the page shifts while loading. In 2024, INP replaced the older FID metric.
Lab data is produced by a Lighthouse test under controlled conditions: a performance score from 0 to 100 and a list of what slows the page down. Issues such as oversized images, late-loading fonts or heavy scripts show up here, with suggestions for fixing them.
Where We Use PageSpeed Insights
Speed is something we look after from the very start when building a site. We open PageSpeed Insights most at these moments:
Before Launch
We measure every site on mobile and desktop before it goes live, and a page with a poor result doesn't launch.
Image and Font Optimization
We serve images in the right sizes and formats, and load fonts and critical styles so they don't delay the page's first view.
Ad Landing Pages
We measure and lighten campaign pages separately, so visitors arriving from ads aren't lost in the first second.
After Changes
When a new section, animation or tag is added to the site, we measure again to confirm that speed hasn't dropped.
Why PageSpeed Insights?
Real-User Data
It shows not just a test environment but what the people who actually visit your site experience.
A Shared, Objective Measure
You can check the results yourself with the same tool, whenever you like; “fast” rests on a number.
Directly Tied to Search
Core Web Vitals are among the signals Google looks at when assessing page experience; speed affects both visitors and visibility.
How We Work on Your Project
On an existing site we first measure the main pages and rank the issues by impact: the biggest gains usually come from images, fonts and unnecessary scripts. We make the fixes and measure again after every step.
On new sites, speed is part of the design from the start: the clean code we write without ready-made themes or page builders starts light from the very first measurement. After launch we keep following the Core Web Vitals in Search Console too.
