Nobody has ever complained that a website opened too quickly. Speed is the first thing a visitor experiences, before they read a word or see a single product. A fast site feels professional and trustworthy. A slow one feels broken, and many people leave before it even finishes loading.
Why speed matters
- Trust. A page that hangs on a white screen makes people wonder whether the business is still open, or whether the site is safe.
- Sales and enquiries. Every extra second of waiting gives a visitor time to press "back" and pick the next result. On a phone with a weak signal, those seconds add up fast.
- Ranking. Google measures real-world loading experience and uses it as one of the signals for ranking pages.
How to measure it
Open pagespeed.web.dev, paste your address and look at the mobile results. Google groups speed into three "Core Web Vitals":
- Largest Contentful Paint (LCP): how long until the main content appears. Aim for under 2.5 seconds.
- Interaction to Next Paint (INP): how quickly the page reacts when someone taps or clicks. Aim for under 200 milliseconds.
- Cumulative Layout Shift (CLS): whether things jump around while loading, like a button moving just as you tap it. Aim for under 0.1.
Then do the most honest test of all: open your site on your own phone, using mobile data, somewhere with average signal.
Simple wins that make a big difference
1. Lighter images
Images are usually the heaviest part of a page. Save them in modern formats like WebP, export them at the size they're actually shown (a 4000-pixel photo in a 400-pixel box is wasted weight), and let images further down the page load only when the visitor scrolls to them.
2. Reserve space for images
Tell the browser each image's width and height in advance. The page then keeps a space for it, and the text doesn't jump when the image arrives. That's what fixes the "moving button" problem.
3. Fonts from your own server
Load only the fonts and weights you actually use, and host them yourself instead of fetching them from another company's server. It's faster, and it means visitors' data isn't sent to a third party just to show a font. We did exactly this on our own site.
4. Fewer third-party scripts
Chat widgets, trackers, social feeds and pop-up tools each add weight and delay, and many of them also collect visitor data. Keep only the ones that clearly earn their place.
5. Caching and compression
Good hosting compresses files and lets browsers keep a copy of things that rarely change, like logos and stylesheets, so returning visitors load the page almost instantly. Just remember to change the file version whenever you update them, so nobody gets stuck with an old copy.
6. Good hosting
Cheap, overloaded hosting can undo all the other work. A reliable host with servers close to your customers, ideally with a content delivery network (CDN), keeps the base speed high.
Speed is a habit
A site that's fast on launch day can slow down over months as new photos, plugins and scripts pile up. Check your PageSpeed score after every significant change, and treat any drop as a bug to fix. Your customers will never thank you for a fast site, but they'll quietly choose it over a slow one.
