Key points

  • If a website or application is easy to use, it will be more popular with the target audience.
  • Screen layout is important for a usable website - the layout should be consistent, so that users can learn where items are and use this knowledge in the future.
  • Navigation is important in a website or application. Users should be able to find a route between any part of the system without getting stuck in a "dead end". They should be able to review their current location within the system easily.
  • Target audiences should be considered when designing a website or application. The reading age, dexterity and interests of the target audience will affect how your system should look and what functionality it should have.
  • Interactive applications and websites are popular because users can feed back their own information and contribute to discussions. Interactive elements also engage users, e.g. quizzes or pop up information.
