1. Content Prioritization – give a priority to the features and content users are most likely to need
  2. Vertical Instead of Horizontal Navigation
  3. Bars, Tabs and Hypertext – less hypertext on mobile pages -> Links appear in the form of bars, tabs and buttons
  4. Text and Graphics – remove promotional or marketing graphics in mobile sites because of the small screen sizes
  5. Contextual and Global Navigation – reduction of global and contextual navigation
  6. Footers – employ footers that provide access to content users often look for on a home page but no footers containing quick links
  7. Breadcrumbs – not in mobile sites
  8. Progress Indicator – guides you through the process (at a registration etc), don’t appear on mobile sites
  9. Integration with Phone Functions – direct calling and text messaging
  10. Localized & Personalized Search – local search results because mobile devices can automatically detect where users are

The most reason for these differences is the less of space. However it is a new area in Webdesign due to the fact that mobile sites are getting more and more popular.
