Free website speed test
A genuine Google Lighthouse test, the same tool Google uses to judge your site. Mobile-first, Core Web Vitals included, and every fix explained in plain English. Takes about a minute.
Starting your check...
We run Lighthouse on mobile settings with realistic throttling, the way Google measures you. Tests take 30 to 90 seconds depending on how heavy the page is.
The numbers Google actually cares about
Since Core Web Vitals became ranking signals, speed stopped being a vanity metric. These are the measurements that move rankings and revenue.
Performance score
The headline 0 to 100 Lighthouse score. Under 50 is a red flag, 90+ is where you want to be. Most unoptimised business sites score 30 to 60 on mobile.
Core Web Vitals
LCP (loading), CLS (visual stability) and blocking time. Fail these in Google Search Console and you are competing with a handicap.
Fixes ranked by impact
Not just scores: the specific opportunities, like oversized images or render-blocking scripts, ranked by how many seconds each would save.
From 34 to 96: a typical Speed Fix result
Slow websites quietly bleed money
Research is unambiguous: 53% of mobile visitors abandon pages that take more than three seconds, and every extra second of load time cuts conversions by up to 20%. Speed is also a confirmed Google ranking factor. If your competitors load in two seconds and you load in six, you lose twice: fewer visitors arrive, and fewer of them buy.

Frequently asked questions
Is this a real Lighthouse test?
Yes. We run the unmodified Google Lighthouse engine in a real Chromium browser on our UK servers, using mobile emulation and network throttling, exactly as Google does for its own measurements.
Why is my score lower than PageSpeed Insights showed me?
It usually is not, but scores naturally vary a few points between runs because networks and servers fluctuate. If you compared a desktop score, expect mobile to be much lower: mobile throttling is far harsher and it is what Google judges you on.
What is a good website speed score?
90 or above is good, 50 to 89 needs improvement, below 50 is poor. For Core Web Vitals: LCP under 2.5 seconds, CLS under 0.1 and INP under 200 milliseconds are the thresholds Google publishes.
Can you fix my speed for me?
Yes, that is our Website Speed Fix service: a fixed £349 one-off where we implement the fixes this test finds. Most sites reach 90+ on mobile, and if we cannot measurably improve your site you get your money back.
How often should I test my site speed?
Monthly at minimum, and after any significant change: new plugins, new theme, big content additions. Speed decays gradually, which is why our care plans include continuous monitoring.
