Responsive Design, Dynamic Content, or Mobile URLs?
If you’re designing the mobile experience from scratch, this question is the first place to start. If you already have a mobile experience set up, then you can just jump to the section that applies to your site. All three options work well for users and for Google, so use the best implementation based on your infrastructure, content, and audience.
|Responsive design||One URL for both desktop and mobile||The page serves basically the same content to all users but detects the device and screen size and builds the layout accordingly. As the screen size gets smaller, the page may show fewer images, less text, or a simplified navigation.|
|Dynamic Serving||One URL for both desktop and mobile||The page serves different content to users of different devices.|
|Mobile URLs||Different URLs for desktop and mobile||The mobile and desktop experience might be completely different.|
