Mobile First

What is Mobile First?

Mobile First is an approach to web design and development where the mobile phone version is designed first and then expanded for tablets and desktops. It forces a focus on the most important content and actions because a small screen leaves no room for clutter. In code, styles for mobile are written first and larger screens are added through media queries. Mobile First is closely related to responsiveness. The term also describes the way Google indexes websites.

Why It Matters

Most website visits now come from mobile devices, so how a website works on them is decisive. Google indexes and ranks websites primarily based on their mobile version, so a weak mobile site hurts search rankings. The Mobile First approach leads to simpler pages, faster loading, and clearer calls to action. Customers can then send an inquiry or complete an order more easily. Retrofitting a desktop website for mobile is usually more expensive and lower in quality.
