Why Mobile-First Design Is the Default (Not the Option)

You don’t need a desktop-first website in 2025. You need a site that converts on phones first. Why?

• 74%+ of traffic is mobile

• Google indexes mobile versions first

• A site that’s hard to use = bounce = lost customer

Amplify designs sites that are built for mobile first before desktop is even considered.

• Sticky headers or CTAs = better retention
