En utilisant ce type de site mobile, vous avez un seul ensemble de fichiers avec une version du contenu, qui est affiché aux utilisateurs quel que soit l’appareil qu’ils utilisent.

Responsive design uses a single codebase and URL for all devices. The website content and layout adapt to the screen size of the user's device (desktop, tablet, mobile) using CSS media queries, ensuring a consistent user experience and making it easier for search engines to crawl and index. Dynamic serving, while also using a single URL, delivers different HTML/CSS based on the user agent, meaning the server detects the device and serves optimized content. A separate domain uses entirely different URLs and content for mobile users (e.g., m.example.com), requiring separate maintenance and potentially splitting SEO authority.
