For the basic orientation of a mobile optimized website are three versions to choose from:
- Responsive web design: The responsive design, there is a URL for all devices. Also the source code is the same. The output of the page is, however, adjusted via CSS to the respective client and its screen size.
- Dynamic Serving: In this case, the content is also available on the same URL. The server returns the contents, however, depends on user agent and fits HTML or CSS to.
- Separate mobile-optimized website: here the mobile content under a different URL available than in the previous examples.
