It will clearly guide the consumer to the item you are selling and allow an effortless purchase procedure. Keeping it simple means creating a set of rules based on the widest audience and sticking to them. For instance, we chose to design for a particular browser version that we know are Java capable for the most part. If you can figure out a way to avoid using Java applets or elements, so much the better. We set our screen resolution to 640x480, the smallest practical screen resolution, so that the site we create would not require users to do a horizontal scroll to view it.

Strive to use Web-safe colors in your designs to attempt to ensure that what your users see is what you intended them to see. Use simple terms for your site navigation so the site visitor has the best chance of finding out where he or she wants to go. Don't overwhelm the user's eye with a crowded site body. Keep it simple and clean, and don't forget that white space is your friend. Make sure you test your site against as many possible degrees of user savvy and Web browser versions as possible before you go live.
