Keep the site clean and simple. Because there are so many different mobile devices with varying screen sizes, it isn't practical to include a lot of design in the site. Keep pages clean and simple so they will display well regardless of the viewer devices.
Place important information at the top of the page. Browsing a mobile site is more difficult than a desktop site, so put the information you don't want visitors to overlook at the top of each page.
Offer radio buttons and lists. Rather than asking visitors to enter text in a mobile device, add radio buttons and lists that provide direct links.
Provide a back button. Some mobile devices lack back buttons, so provide them.
Keep page size small. The maximum page size for a mobile page is only 20 kilobytes. Focus on great content rather than design graphics.
