Mobile-first design: best practices

For most trade and service businesses, 60–75% of traffic is mobile. Yet most sites are still designed on a desktop and squeezed down afterwards. That is backwards.

Design for the thumb

The primary action should be reachable without stretching, and large enough to tap with certainty. If the main CTA is a small link in a hamburger menu, you are losing leads.

Respect the connection

Assume a phone on a weak signal in a van. Compress images, defer anything non-essential, and never block the first paint with a giant hero video.

One column, clear order

Mobile is a single column. Decide the exact order a visitor should read: outcome, proof, action. Everything else is secondary.

Test on a real device

Emulators lie. Load the site on an actual mid-range phone before you ship. It is the cheapest QA you will ever do, and it catches the things that quietly cost conversions.
