Mobile-First Design: Why Your Website Must Work on Phones First

Here's a stat that should shape every web design decision: over 70% of web traffic in South Africa comes from mobile devices. In some demographics, it's over 90%.

What mobile-first means:

Mobile-first design doesn't mean making your desktop site "also work on phones." It means designing for the phone FIRST, then enhancing for larger screens. The difference is fundamental:

• Content priority — What's most important on a 375px screen?
• Touch targets — Buttons need to be at least 44px for comfortable tapping
• Thumb zones — Key actions should be reachable with one hand
• Loading speed — Mobile connections are slower, every KB matters
• Data costs — Many SA users are on prepaid data

Common mobile mistakes:

1. Tiny text — If users need to pinch-zoom, you've failed 2. Horizontal scrolling — Content must fit the viewport width 3. Slow images — Unoptimized hero images that take 10 seconds to load 4. Pop-ups — Intrusive pop-ups on mobile are a Google penalty factor 5. Complex navigation — Hamburger menus are fine, mega-menus on mobile are not 6. Forms with too many fields — On mobile, every field is friction

The business impact:

Google has been using mobile-first indexing since 2019. This means Google ranks your site based on its mobile version, not desktop. If your mobile experience is poor, your search rankings suffer across all devices.

• Test your site at mobile-friendly test on Google
• Check your Google PageSpeed score on mobile

• Ask 5 people to find your phone number on your site using their phones
