We Practice What We do

Anyone can say their website is fast. Any web designer can tell you they build for performance, that speed is a priority, that your site will load quickly on any device.

Words are easy. So instead of asking you to take ours for it, we'd rather show you.

Test it yourself — right now

Go to pagespeed.web.dev — Google's free, public tool for measuring website performance. Paste in our URL: sitematestudio.com. Run the test.

You'll see our scores on both mobile and desktop. We consistently score above 90 on both — which puts us in the top tier of website performance by Google's own measurement.

That's not a screenshot we took on a good day. That's a live test you're running yourself, right now, on our actual website. No filters, no editing, no cherry-picking.

If we can't build a fast website for ourselves, why would you trust us to build one for you?

What those scores actually mean

Google PageSpeed Insights measures something called Core Web Vitals — a set of real-world performance metrics that reflect how a website actually feels to a visitor:

LCP (Largest Contentful Paint) — how quickly the main content of your page loads and appears on screen. Google considers anything under 2.5 seconds good.

FID / INP (Interaction responsiveness) — how quickly your site responds when someone taps a button or interacts with the page. A slow response here makes a site feel laggy and unresponsive.

CLS (Cumulative Layout Shift) — whether elements on the page jump around while loading. You've experienced this when you go to tap something and it moves just as you tap it. Annoying for users, penalised by Google.

A score above 90 means all three of these are in the green. It means the site loads fast, responds instantly, and doesn't shift around on the screen. It means Google considers it a high quality experience — and rewards it accordingly in search rankings.

Why we're telling you this

We build websites for local businesses. Our whole pitch is that a fast, well-built website brings in more customers — better rankings, lower bounce rates, more calls and enquiries.

It would be pretty hollow to say all of that and then have our own website score a 65.

Every choice we made when building sitematestudio.com — the framework, the hosting, the way images are handled, the way fonts load, the structure of the code — was made with performance as a priority. Not as an afterthought once everything else was done. From the start.

That's exactly how we approach every client website we build. The same standards, the same attention to the details that most people never see but that Google and your visitors absolutely feel.

Now test your current website

If you already have a website, go back to pagespeed.web.dev and run the same test on your own URL.

If your score is below 90, your site is slower than it should be. If it's below 70, it's likely costing you customers and rankings right now — silently, every day.

The good news is that performance issues are fixable. A rebuild with modern technology, proper hosting, and optimised images can take a site from the 50s to the 90s. The difference in how it feels — and how it performs in search results — is significant.

What we use to achieve this

Our own site, and every client site we build, uses the same core stack:

Next.js — a modern React framework that handles server-side rendering and static generation, meaning pages are pre-built and delivered to visitors instantly rather than assembled on demand.

Vercel — global CDN hosting that serves your website from the location closest to each visitor. Someone in Manchester gets the site from a Manchester edge server. Someone in Edinburgh gets it from there. No unnecessary distance, no unnecessary latency.

Sanity — a headless CMS that keeps content separate from code. Pages load fast because the CMS isn't doing heavy lifting at the point of delivery — it's already done.

Optimised images — every image is compressed, converted to modern formats, and sized correctly for the screen it's being served to. A mobile visitor doesn't download a 4000px wide image designed for a desktop monitor.

None of this is magic. It's just good, modern web development done properly.

Don't take our word for it

Test our site. Test yours. Compare the numbers.

If yours isn't where it should be and you want to talk about what a properly built website could look like for your business — that's exactly what the free demo is for.
