Usability
Usability is a measure of how easy a website, application, or interface is to use. Good usability means that users can find information, place an order, or contact support without difficulty.
To evaluate usability, analysts look at user behaviour metrics that show page depth, bounce rate, time on page, and form conversion rates. Usability testing adds direct observation of real users completing a specific task, while a researcher records where they encounter difficulties.
Usability Principles
- Clear navigation: users can understand within a couple of seconds where they are and where to go next.
- Obvious labels: “Get a consultation” works better than “Submit”.
- A short path to the goal and as few form fields as possible.
- Fast loading and proper functionality on mobile devices.
- Feedback for every action: confirmations, loading indicators, and clear error messages.
