More than 60% of legal searches now happen on mobile devices. Google uses mobile-first indexing, meaning the mobile version of your website is the primary version for ranking purposes. For law firms, mobile optimization isn't optional—it's essential for reaching clients when they need you most.
Mobile-First Indexing Explained
Google now primarily uses the mobile version of your website for indexing and ranking. This means:
- Mobile content is what Google sees first
- Mobile performance affects all rankings
- Desktop-only content may not be indexed
- Mobile user experience impacts search visibility

Mobile-First Mindset
The best approach is designing for mobile first, then enhancing for desktop—not the other way around. When you prioritize the mobile experience, you ensure that the majority of your potential clients have an excellent experience, regardless of device.
Remember that mobile users often have urgent needs. Someone searching for a "DUI lawyer" at 2 AM on their phone needs to reach you immediately. A slow, clunky mobile experience means they'll tap the back button and call your competitor instead. Mobile optimization isn't just about SEO—it's about being there when clients need you most.
