Q

Give an example of clear navigational structure on a website.

A
  • The user should be able to navigate without needing to read separate instructions, for example, forward/back buttons on a website should be clearly labelled and in the same place on every webpage
  • The design should guide the user through a task, such as booking a holiday in a logical series of small steps.

Q

Define ‘consistency of signposting’?

A

Users should never wonder what to do next. All buttons and menus should appear in the same place throughout the design. This is intuitive for the user.
