In the website context, this means sites that are designed to be viewed on devices with smaller screen dimensions than desktops.

Other characteristics of users with mobile devices:

  • They may not be using a mouse, but a touch screen.
  • They may have very specific aims when visiting a site, such as finding directions.
  • They may just be killing time.

Note that some mobile devices have screen resolutions approaching desktop resolution, so may not want a "mobile" version of a particular site.
