In 2026, the phrase "mobile-friendly" is no longer a suggestion—it is the baseline for survival. Google now almost exclusively uses the mobile version of your website for indexing and ranking. If your mobile site is a 'lite' version of your desktop experience, you aren't just providing a poor user experience; you are actively hiding your best content from search engines.
For Brisbane business owners, from Fortitude Valley retailers to Northside trade services, the stakes are high. Local customers are searching on the go, often while standing on a street corner or commuting on the CityCat. If your mobile site doesn't deliver, your competitors will.
Here is how to ensure your site survives and thrives under mobile-first indexing.
1. Audit Your Content Parity
The biggest mistake we see at Local Marketing Group is "content stripping." To make a site load faster on mobile, developers often hide text, images, or accordions that exist on the desktop version.
The Rule: If it’s not on your mobile site, Google doesn't see it for ranking purposes.
Action Step: Use a tool like Screaming Frog to crawl your site as "Googlebot Smartphone." Compare the word counts and headings between your desktop and mobile views. Brisbane Insight: Local service providers often hide their service area lists on mobile to save space. Don't do this. Ensure your list of suburbs (from Ascot to Yeronga) is visible and crawlable on mobile to maintain your local search visibility.
2. Optimise for the 'Fat Thumb' and Fast Eyes
User experience (UX) signals are heavily weighted in mobile-first indexing. Google looks at how easily a user can interact with your site without zooming or accidental clicks.
Button Sizing: Ensure all Call-to-Action (CTA) buttons are at least 48x48 pixels. Font Legibility: Use a base font size of at least 16px. If a customer has to pinch-to-zoom to read your pricing, they will bounce. Interstitials: Avoid intrusive pop-ups that cover the entire mobile screen. These can lead to ranking penalties. Use a small banner instead.
3. Technical Alignment: Metadata and Schema
Many businesses treat their mobile site as a secondary thought when it comes to technical SEO. This is a critical error. Your mobile site must contain the exact same structured data and metadata as your desktop site.
Structured Data: Ensure your Schema markup is present on both versions. If you have LocalBusiness schema on desktop but omit it on mobile, Google may struggle to display your rich snippets. If you've noticed your stars or prices disappearing from Search, you might be falling into common schema implementation traps. Metadata: Title tags and meta descriptions should be identical across both versions. Don't shorten them for mobile; Google handles the truncation on the SERP (Search Engine Results Page) itself.
4. Prioritise Performance (Without the Obsession)
Speed matters, but it’s not the only thing that counts. While you should aim for fast load times on 4G and 5G connections, don't sacrifice essential brand elements just to get a perfect speed score.
Focus on Largest Contentful Paint (LCP)—how quickly the main content of your page loads. For an Australian audience, this means using a local CDN (Content Delivery Network) or hosting your site in an Australian data centre (preferably Sydney or Brisbane) to reduce latency. Remember, it’s about the user’s actual experience, not just chasing green scores on a testing tool.
5. Image and Video Optimisation
Mobile-first indexing requires a different approach to media.
1. Use Responsive Images: Use the srcset attribute to serve smaller image files to mobile devices and larger ones to desktops.
2. Format Matters: Use WebP or AVIF formats instead of heavy PNGs or JPEGs.
3. Lazy Loading: Ensure images below the fold load only when the user scrolls to them, saving initial bandwidth.
4. Video Placement: Ensure videos don't break the mobile layout. Use a responsive container so the video scales to the width of the smartphone screen.
Summary Checklist for Brisbane Businesses
[ ] Does my mobile site have the same primary content as my desktop site? [ ] Are my mobile headings (H1, H2, H3) identical to desktop? [ ] Is my "Click to Call" button prominent and easy to hit with a thumb? [ ] Have I verified my mobile site in Google Search Console? [ ] Are my images compressed and responsive?

Mobile-first indexing isn't a technical hurdle to clear; it’s a reflection of how your customers actually behave.
