Google switched to mobile-first indexing meaning it uses the mobile version of your website as the primary version for ranking decisions. If your mobile experience is poor, your rankings suffer across all devices, not just mobile. Here is how to ensure your site meets Google’s mobile standards.
What Mobile-First Indexing Means for Your Site
Mobile-first indexing means that Googlebot primarily crawls the mobile version of your site when assessing content, structure, and signals for ranking. If your mobile site has less content than your desktop site, shows different structured data, has different meta tags, or blocks images that appear on desktop, those differences will negatively affect your rankings even for desktop searchers.
Testing Your Mobile Performance
Use Google’s Mobile-Friendly Test at search.google.com/test/mobile-friendly to check whether Google considers your pages mobile-friendly. Use Google PageSpeed Insights at pagespeed.web.dev to see your mobile performance scores and get specific recommendations. And check Google Search Console’s Mobile Usability report to identify any mobile usability issues across your entire site.
Common Mobile SEO Issues to Fix
Tap targets that are too small and close together make navigation frustrating on touchscreens and are a common mobile usability issue flagged by Google. Ensure buttons and links are at least 48 pixels tall and 48 pixels wide with adequate spacing between them. Text that is too small to read without zooming forces users to zoom in and is another flag Google penalises. Use a base font size of at least 16 pixels for body text. Content wider than the screen requires horizontal scrolling and signals poor mobile optimisation. Ensure all content is contained within the viewport width.
Responsive Design vs Separate Mobile Site
Google recommends responsive design as the preferred approach for mobile-friendly sites because it uses a single URL and the same HTML content for all devices, with CSS controlling how content is displayed at different screen sizes. Separate mobile sites on different URLs such as m.domain.com create additional complexity for canonicalisation and link equity management and are generally more difficult to maintain than responsive design.
