Domestic credit card companies and wireless operators want to deliver promotional information as well as the information for users on the site. A careful UX design is needed because promotional information can degrade the satisfaction of the users. In addition, too extensive information is provided on one site and users are confused about where to look for the information they need. Based on advanced research, study was conducted of the domestic web sites of wireless operators and credit card companies and we discussed that study with 12 users. Promotional information can be efficient with understated image. Users can find information easily from the site with fewer hierarchy of steps. The numbers of the menu that is presented at a time should not exceed nine.
