Frequently asked questions
Is the PageSpeed Insights Checker free?
This tool requires an active one-time membership to use - pay once and unlock this tool plus every other gated tool on the site, no subscription, no ads.
What is Core Web Vitals?
Google's set of page-experience metrics measuring loading performance, interactivity, and visual stability - they factor into search rankings, so improving them can have a direct SEO benefit alongside better user experience.
Why is my mobile score lower than my desktop score?
Mobile devices typically have less processing power and often slower network conditions than desktops, so the same page tends to score lower on mobile - and Google primarily evaluates mobile performance for ranking purposes.
