Picture how somebody actually finds you. They're not at a desk. They're sitting in a truck in a parking lot, or standing in their kitchen, on a phone, on a cell signal that's doing its best. They searched for what you do, they tapped your name, and now they're waiting.
If they wait too long, they hit back and tap the next business. They will never know they almost called you, and you will never know they existed.
That's not a metaphor. It's the actual test I run before I put a site live: I take it out to a parking lot, on a cell signal, on a phone, and see how long I'm standing there. A site that feels quick on your office wifi can be a completely different animal on one bar in a truck outside a job.
What makes a site slow
- Huge photos. The single most common cause by a mile. A photo straight off a phone can be 4MB. It should be closer to 100KB, and it will look identical.
- Too many plugins. Every add-on loads its own code. Ten of them and the page is dragging a trailer.
- Video that autoplays on a phone. A background video can be several megabytes before anybody's read a word.
- Fonts and trackers. Each one is another round trip before the page can finish.
Check yours right now, free
Go to pagespeed.web.dev, paste your address, and look at the mobile score — not the desktop one. Desktop is always flattering and almost nobody is on it.
What the number means: under 50 is a real problem you're losing customers to. 50–80 is normal and worth improving. Above 85 is genuinely good. For reference, the last site I built came in at 85 on mobile and 93 on desktop — and you can go check that yourself.
Read the right number
PageSpeed shows you two different things and people mix them up. Near the top, if enough real people have visited your site, you may see a section based on actual visits over the last month. That's the real world and it's the one that counts. Below it is a lab test run on a simulated phone, which is useful for finding what's wrong but is not a measurement of what your customers felt.
So: if the field data says you're fine and the lab score says 40, you're probably fine. If the field data is bad, believe it.
What you can fix yourself this afternoon
Resize the photos. This is most of it, most of the time. Open a free tool like Squoosh in your browser, drag a photo in, set the width to about 1600 pixels, save it as WebP, and put that on the site instead. A 4MB photo usually lands around 150KB and you genuinely cannot tell the difference on a screen.
Turn off anything that plays by itself. Background video, auto-playing sliders, animated banners. They cost real seconds and almost nobody reports liking them.
Count your plugins. If you're on WordPress, open the plugin list and be honest about how many of those you're actually using. Every one is more code your customer downloads before they can read a sentence.
What not to buy: a plugin that promises to make your site fast. You are fixing a code-weight problem by adding more code. Sometimes they help, often they break the layout in ways nobody notices for a month, and none of them fix a 4MB photo.
Where hosting comes into it
Cheap shared hosting puts your site on a machine with a few hundred other sites, and when one of them has a busy morning, yours gets slower. It's not usually the main problem — the photos are — but it's the floor under everything else. If you've fixed the obvious things and the site still takes a beat to start responding at all, that's the hosting talking.
Why the sites I build start fast
I hand-code them. There's no page builder generating layers of markup, no plugin stack, and every photo gets converted and saved at two sizes so a phone downloads the small one and a desktop downloads the large one. It isn't a trick or a magic host. Most of speed is just not putting unnecessary weight on the page in the first place.
If yours comes back badly, it's often a couple of hours of work rather than a new website. That's worth knowing before somebody sells you a rebuild. And if you want me to look at the number with you, send me the address — that part's free.
