Google uses mobile-first indexing. Discover how to optimize your site's mobile experience for better SEO.
Since 2019, Google uses mobile-first indexing: it's the mobile version of your site that gets indexed first. More than 60% of global web traffic comes from mobile devices, making mobile optimization essential.
A site not optimized for mobile will be penalized in search results, have a high bounce rate, and lose potential conversions.
The viewport tag tells the browser how to size and scale content on different screen sizes. It's the foundation of responsive design.
Recommended configuration:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Responsive design allows your site to automatically adapt to all screen sizes: smartphones, tablets, computers. It's Google's recommended method for mobile compatibility.

Buttons and links should be at least 48x48 pixels to be easily tappable with a finger.
Use a font size of at least 16px for body text, readable without zooming.
Keep enough space between clickable elements to avoid accidental taps.
Content should fit the screen width without requiring horizontal scrolling.
Favicons reinforce your brand image in tabs, bookmarks, and mobile search results. Their absence can give an unprofessional impression.
