98% of bio link traffic comes from a phone. That single fact should drive every design choice on your bio page. Most of them do not. Here are eight mobile-first rules that separate pages that convert from pages that bounce.
1. Thumb-zone buttons
On a modern phone, the comfortable tap zone is the bottom two-thirds of the screen. Put your primary CTAs there, not at the very top. The hero headline can sit above. Buttons belong where thumbs live.
2. 44px minimum tap targets
Apple and Google both recommend a minimum 44x44px tap target. Anything smaller feels fiddly and fails accessibility. Buttons should be comfortably tappable with wet hands.
3. Single-column layout
Multi-column bio pages look clever on desktop and break on mobile. One column, stacked. No exceptions.
4. Legible type
16px minimum for body text, 20 to 24px for headlines, high contrast ratio. Trendy light gray on white looks great in screenshots and falls apart on a phone in bright sunlight.
5. Fast load
Aim for under 1.5 seconds on 4G. Every extra second costs you around 7% of conversions. Heavy background images and multiple video embeds are the usual culprits.
6. No autoplaying video
Autoplay burns mobile data, mutes on iOS, and annoys everyone. If you want a video, make it click-to-play.
7. Sticky CTA
A sticky "primary action" button at the bottom of the screen lifts conversions 10 to 25% on mobile. Users always know what the next action is.
8. Test on a real device
Chrome DevTools mobile mode is not a substitute for holding a phone. Test on your worst phone, on 4G, in bright light. If it works there, it works everywhere.
Common mobile bio page sins
- Tiny social icons stacked horizontally (fails the tap-target test).
- Horizontal sliders with no signal that there is more.
- Pop-ups that cover the CTA on short screens.
- Text over busy background images.
