Site speed for Cardiff trades: from 50 to 90 on PageSpeed Insights
Most Cardiff trade websites load so slowly that one in three customers leaves before the phone number even appears. Fixing it isn't magic — it's five specific changes, and four of them don't need a developer.
Why slow sites cost you jobs, not just rankings
A slow website isn't a technical problem. It's a customer problem.
Imagine a Cardiff homeowner with a leaking boiler. She Googles 'emergency plumber Cardiff' at 9pm. She taps the first result. She stares at a blank white screen. After two seconds, she's already wondering if she tapped the right thing. After four seconds, she's tapped the back button and gone to the next plumber on the list. She never sees your phone number. She never sees your reviews. She doesn't even know you exist.
That story plays out hundreds of times a week on slow Cardiff trade sites. The customers most likely to call you — the urgent ones, on a phone, with somewhere to be — are also the ones with the least patience for a slow page. Speed isn't a ranking factor as much as it's a staying-on-the-page factor. You can be the best plumber in Roath; if your page takes five seconds to load, you'll never know how many customers tapped away first.
Google measures this with a tool called PageSpeed Insights, and the score they give your homepage on a phone has two jobs: it tells Google where to rank you, and it tells you how many customers are quietly leaving before they reach your number. Most Cardiff trade sites we audit score between 35 and 55 out of 100 on mobile. The target is 90. Here's how to get there.
What your customer actually sees in the first three seconds
The reason a slow site loses customers isn't 'the score is bad'. It's that nothing useful appears on the screen for the first few seconds. Your phone number, your reviews, your service area — none of it is visible while the page is still loading. The customer is staring at a blank white rectangle.
The map below shows what happens on a typical slow Cardiff trade site when 100 customers tap your link from a Google search:
Read the diagram by the numbers, not the boxes. Out of 100 Cardiff customers who tap a slow trade site, around 50 leave before they can do anything useful. The same site, fixed properly, keeps 85 of them on the page — and the booked-job count roughly doubles, without spending a penny more on Google Ads.
The five fixes ahead are ranked in the order that gives you the biggest gain per hour of work. The first two together are worth more than the other three combined.
The five fixes, ranked by jobs-per-hour-of-work
1. Shrink the big photo on your homepage (worth ~2 seconds)
The single biggest reason Cardiff trade sites are slow: the big photo at the top of the homepage was uploaded straight off a phone. A modern phone takes a 4000×3000 photo that weighs around 3MB. The customer's phone then has to download all 3MB just to show a photo at, say, half the screen width — when 80KB would have done the same job. On 4G that's around two seconds wasted on a single image.
Two ways to fix it:
- The easy way: on a WordPress site, install ShortPixel or Smush. Both shrink every photo on your site in one go, and keep doing it for new uploads. Free up to a few hundred photos.
- The done-for-you way: on a Loyalleads-built site this is handled automatically — every photo is served at the right size for the device looking at it. Nothing for you to do.
Either way, audit every photo on your site once. It's the highest-paying afternoon of work you'll do this year.
2. Turn off the tracking scripts nobody checks (worth ~1 second)
Open your homepage. Right-click. Choose 'View page source'. Count how many bits start with 'https://' that aren't your own site. Most Cardiff trade sites have between 8 and 15 of these — Google Analytics, Google Tag Manager, Facebook Pixel, a heatmap tool from 2019, a chat widget nobody answers, a LinkedIn pixel from when you tried LinkedIn ads.
Each one of these adds a tiny extra wait. None of them are visible to the customer; all of them slow your page down.
Rule of thumb: if nobody on your team has logged into the dashboard for a tracking script in the last 30 days, switch it off. You keep Google Analytics if you actually use it; everything else can go. A typical Cardiff trade site that does this drops 5–8 of these scripts and gains around a second of load time straight away.
3. Move your site to UK hosting (worth ~0.5 seconds)
A surprising number of Cardiff trade sites are hosted on cheap shared servers based in Germany, Ireland or even Texas. Every extra mile between your customer's phone and the server adds a tiny delay — usually 50 to 200 milliseconds. Not enormous on its own, but it's the first thing the customer waits for, and it stacks on top of every other delay.
UK-based hosts (Krystal, Cloudflare, Vercel, Netlify all have UK servers) get the first byte to a Cardiff phone significantly faster, and the cost is similar — typically £10–£20 a month. This is a one-evening migration and the difference is immediate.
If you're not sure where your site is hosted, ask whoever built it, or run your domain through a free 'where is my website hosted' lookup tool. If the answer is anywhere outside the UK, that's a half-second you can get back.
4. Switch off the WordPress plugins you don't need (worth ~0.5 seconds)
Every active plugin on a WordPress site loads its own code on every page, whether the page uses it or not. A typical Cardiff trade WordPress install has 18–25 active plugins; in our audits we routinely switch off 12–15 of them with zero functional loss — they're left over from old projects, old themes, old marketing experiments.
Audit your plugins once a quarter. If you (or whoever runs the site) can't say what a plugin does in one sentence, switch it off. If nothing breaks in a week, delete it. Each one you remove makes the rest of the site fractionally faster.
5. The one fix that needs a developer (worth ~1 second)
The last fix is the one you can't do yourself. It's a small change to how the visible-on-load portion of your page is built — so the browser can paint the page before it's finished downloading all the styling for the parts you can't see yet. On a slow site it's worth around a second; on an already-fast site, around half a second.
If you're on WordPress, the Autoptimize plugin handles it automatically. If you're on a modern build (Next.js, Astro, anything custom built in the last two years), it's already done. If you're on an old custom site or a page-builder theme, this is the one you'd hire a developer to handle — half a day of work, usually under £200.
It's the smallest win on the list per hour of effort, which is why it's last. Do the first four first.
How to check before and after — without trusting an agency
Don't trust anyone who says 'your site is slow' without showing you a number. The number is free and you can run it yourself.
- Go to pagespeed.web.dev on a laptop or phone.
- Paste your homepage URL.
- Look at the Mobile score. That's the one that matters — most Cardiff customers are on a phone.
- Run it three times and write down the median (the middle number). The score can wobble 5 points either way depending on how busy the network is at the time.
Run it once before you change anything. Then once after each fix. You'll see the score climb in real time — and you'll know, for the first time, exactly how much each change was worth.
The five fixes above move the typical Cardiff trade site from 45 to 55 up to 85 to 95 in a focused half-day of work. That's not a marginal gain — that's the difference between losing half the customers who tap your link and keeping most of them.
