Mobile-First SEO – Why It’s Non-Negotiable in 2025

Why it matters

Mobile devices account for 66.46% of all web traffic in Australia, with Google commanding over 97% of mobile searches. Mobile-first indexing means Google primarily uses your mobile site for ranking.

Australia has 34.4 million active cellular mobile connections – that’s 128% of the total population. The numbers are clear: if your website isn’t optimised for mobile, you’re invisible to the majority of potential customers.

Google now indexes websites based on their mobile version first. This means if your mobile site is slow, hard to navigate, or missing content, your rankings suffer – even for desktop searches.

Essential mobile SEO practices:

Ensure responsive design that adapts to all screen sizes. Optimise page loading speed (aim for under 2.5 seconds). Use large, easily tappable buttons and links. Avoid intrusive pop-ups that frustrate mobile users. Implement structured data for rich results.

Google’s Core Web Vitals focus on loading speed (Largest Contentful Paint), interactivity (First Input Delay), and visual stability (Cumulative Layout Shift). Poor performance in these areas directly impacts rankings.

For local businesses, mobile optimisation is even more critical. People searching on mobile are often ready to make a purchase or visit your location immediately. Make sure your phone number, address, and directions are easily accessible.

Use tools like Google PageSpeed Insights and Google Search Console to identify and fix mobile issues. Regular testing across different devices ensures consistent user experience.
