What is Mobile-First Indexing and Why Your Business Should Care

Did you know that over 60% of searches now happen on mobile devices? If your website isn’t built for mobile, you could be missing out on customers and Google might be ranking your site lower as a result.


What is Mobile-First Indexing?


Mobile-first indexing means that Google uses the mobile version of your website as the starting point for what gets indexed and how your site ranks in search results. In short, if your mobile site isn’t up to scratch, your overall SEO could take a hit, even for desktop users.

Why Has Google Shifted to Mobile-First?


The majority of people now browse and shop using their phones. Google wants to deliver the best possible experience for users, no matter what device they’re on. If your site is hard to use or slow on a phone, visitors will leave—and Google notices.


What Does This Mean for Your Business?


If your website isn’t mobile-friendly, you’re potentially:
  • Losing out on new leads and customers
  • Falling behind competitors with better mobile experiences
  • Missing opportunities to appear in local and mobile search results


Quick Mobile-Friendly Audit: Can You Say "Yes" to These?


  • Does your site look great and work smoothly on a mobile phone?
  • Is text easy to read without zooming in?
  • Do buttons and links work well on a small screen?
  • Does your site load quickly on mobile data connections?

If you answered "no" to any of these, it’s likely your site isn’t ready for mobile-first indexing—and you could be losing business because of it. 


What’s Next?


Over the next few weeks, we’ll break down how Google’s mobile-first approach works, what mistakes to avoid, and how to make sure your website is set up for success.
