Most of your customers will see your website on a phone, on a mobile connection, while doing something else. Here's what that means for how it should be built.
If you build a website on a fast office fibre connection and a 27-inch monitor, you'll build a different website than the one your customers actually use.
In Mauritius, the majority of web traffic is mobile. A large share of it is on a 4G signal that is not as fast as the marketing suggests — especially outside the main urban centres, and especially inside buildings. A website that loads in two seconds on fibre can take eight on 4G. Eight seconds is long enough for someone to give up and book the place down the road.
Mobile-first doesn't mean 'it also works on mobile.' It means we design the mobile experience first — the one most people will have — and then expand it for desktop. Every image is compressed and served in WebP. Every container has a defined size so nothing shifts while it loads. The call and WhatsApp buttons are visible without scrolling, because that's the action a mobile visitor is most likely to take.
We test on throttled 4G, not on fibre. If a page doesn't load in under 2.5 seconds on a throttled mobile connection, it's not done. That's not a nice-to-have. It's the difference between a website that earns its keep and one that doesn't.
