Short answer
If you built your site on Squarespace, Wix, or a modern WordPress theme, it's already mobile-friendly. If it's an older custom-built site, you likely have a problem — and it's hurting your Google rankings.
How to check if your site is mobile-friendly
- Go to search.google.com/test/mobile-friendly
- Enter your website URL
- Google will tell you if there are issues and what they are
Most common mobile problems
- Text too small to read — font size below 16px
- Buttons too close together — hard to tap on a phone
- Content wider than screen — horizontal scrolling required
- Images not scaling — images are fixed-width and overflow on small screens
- Pop-ups covering content — Google penalizes intrusive interstitials on mobile
How to fix it
If you're on Squarespace, Wix, or Showit: Use their built-in mobile editor to preview and adjust. These platforms handle most mobile issues automatically.
If you're on WordPress: Switch to a mobile-responsive theme. Most modern themes (Astra, GeneratePress, Kadence) are responsive by default.
If you have a custom-built site: You need a developer to add responsive CSS or rebuild using a modern framework.
Why it matters for SEO
Google uses mobile-first indexing — meaning it crawls your mobile site, not your desktop site, to determine your search rankings. A poor mobile experience directly hurts where you appear on Google.
