Meeting user expectations is important for good usability. User research, reviewing competitors, and following guidelines can help ensure expectations are met. When expectations are broken, users may deny the issue or resist interacting. For example, users repeatedly clicked "Buy Now" on a site that updated the basket instead of taking them to an expected "Your Basket" page, showing unexpected behaviors must be obvious. Resistance to change was also seen when users did not want to learn a new Office interface. A site's structure, behavior, language, and appearance should match user expectations to have good usability.
