How fast is your website?

Get your Google Lighthouse performance score, Core Web Vitals, and the biggest fixes to speed up your site — for mobile and desktop. A slow site quietly costs you rankings and sales; find out where you stand in under a minute.

Powered by Google's PageSpeed Insights. We send only the URL you enter to Google to run the audit — nothing else is stored or tracked. Lab metrics reflect a single simulated test and can vary between runs; real-world data is shown when Google has enough Chrome traffic for the site.

What the numbers mean

Your score, decoded

The three things Google actually measures.

  • 01

    Largest Contentful Paint (LCP)

    How quickly the main content of your page appears. Aim for under 2.5 seconds. Slow LCP usually means heavy images, slow hosting, or render-blocking code.

  • 02

    Cumulative Layout Shift (CLS)

    How much the page jumps around as it loads. Aim for under 0.1. High CLS — from images without dimensions or late-loading ads — frustrates visitors and tanks trust.

  • 03

    Total Blocking Time (TBT)

    How long the page is frozen and unresponsive while scripts run. The main cause is too much JavaScript — exactly what bloated WordPress themes and plugins pile on.

Why speed pays

A slow site is a leaky funnel

Speed isn't vanity. Core Web Vitals are a Google ranking factor, so a faster site climbs higher in search. And every extra second of load time pushes visitors to bounce before they ever see your offer — you're paying for traffic that leaves at the door.

If your score is stuck in the 30s and 40s on mobile, plugins and a heavy theme are usually the cause — and no amount of caching fully fixes it. A lean Next.js rebuild ships pre-rendered pages from a fast edge, which is why migrated sites routinely jump into the 90s and stay there.

Speed FAQ

Website speed questions

Google's Lighthouse performance score runs from 0 to 100. A score of 90 or above is considered fast, 50–89 means there's clear room to improve, and below 50 is slow enough to hurt both your rankings and your conversion rate. Many WordPress sites loaded with plugins score in the 20s and 30s on mobile.

Core Web Vitals are the three speed and stability metrics Google uses as a ranking signal: LCP (Largest Contentful Paint — how fast the main content loads), CLS (Cumulative Layout Shift — how much the page jumps around while loading), and INP/TBT (responsiveness to interaction). This test reports them so you can see exactly where your site stands.

The usual culprits are too many plugins, a heavy theme, render-blocking scripts, unoptimised images, and slow server response from shared PHP hosting. Each adds weight and delay. Rebuilding on a modern framework like Next.js removes most of this by shipping lean, pre-rendered pages from a fast edge — which is why migrated sites typically jump from the 30s into the 90s.

Yes — directly. Core Web Vitals are a confirmed Google ranking factor, so faster sites tend to rank higher. Speed also affects revenue: studies consistently show that every extra second of load time increases bounce rate and reduces conversions. A faster site usually means more traffic and more sales from the same marketing spend.

Start with the opportunities this test lists — they're ordered by the time you'd save. Common wins include compressing images and serving modern formats, removing unused JavaScript and CSS, deferring third-party scripts, and improving server response. For sites stuck in the low scores, a rebuild on Next.js is often the fastest route to a 90+ score that stays there.

Yes, it's completely free with no sign-up. It runs a real Google Lighthouse audit through the official PageSpeed Insights API — the same engine behind Google's own tool — so the scores are authoritative. Results reflect a single test and can vary slightly between runs depending on network and server conditions.
