Usability Heuristics

Usability heuristics are broad principles used to review whether an interface is understandable and easy to operate. Common examples include clear system feedback, consistent terminology, error prevention, and giving users ways to recover from mistakes. A reviewer might check whether a handyman site's booking form shows a clear confirmation after submission or uses familiar names for services. A heuristic review is an expert-led evaluation, not the same as usability testing, where actual people attempt tasks and reveal unexpected problems. Heuristics can identify likely friction quickly, but they cannot predict every visitor's behavior. Findings should be prioritized and checked against real user needs when practical.
