Keep in mind that users spend most of their time on other sites, which is where they form their expectations for how the Web works on your site. Provide feedback to inform users where they are in your site. Feedback provides users with information they need to proceed to the next activity. Feedback can be as simple as changing the color on a link after it has been clicked by a user. Frequently users are unaware when they have clicked to a different Web site.
Logos are the most effective way to ensure that users know where they are.
Keep Web page size at or below 30,000 bytes for an acceptable downloading time. The maximum allowable page size is 30,000 bytes in order to achieve desired response time of 10 seconds using a modem . Use frames only when other design solutions are not adequate. Frames may take longer to design, develop, and maintain. Splitting a page into frames can be confusing for users since frames can break the fundamental user model.
