The mobile Web is much discussed and a point of contact you should be taking advantage of. Below are some basic points you should consider when looking at how your site will display on the mobile Web.

Mobile phones have small screens and limited memory
Your site will not display the same way it does on a computer screen. To keep it as simple and usable as possible, design with single table layout, and use only the essential images and animation.

Ensure that your site is easy to navigate
Given the restrictions on mobile controls (there’s no mouse!) limit scrolling to only one direction if you can. Write your links clearly and simply, and don’t include too many per page. To avoid excessive amounts of links, think carefully about how you structure links from one page to another, using them to facilitate navigation.

Think about the types of people visiting you site
Will people browsing from their mobile phones be goal oriented, looking for amusement, or returning often for updates of some kind? Thinking in these terms should help you set up paths of navigation. 

Do not use pop up windows
Pop up windows are irritating on computers as it is. On a small screen they’re potentially devastating and you should avoid them.

Test for various screen sizes
There are many different kinds of screens out there. You should not only design with this in mind, but test your site in as many different mobile phones as possible as well. While some are quite advanced, many phones are still only capable of the most basic display.

These points should act as a starting point for taking a look at your site. Whether your solution would be to build a separate site for mobile or adjust your own, you need to get involved in this space.
