User experience, often abbreviated as UX, refers to the interaction and satisfaction a user derives from a product. It encompasses how users perceive and evaluate the quality of a product. In today's web development landscape, UX is pivotal, ensuring that websites and apps are optimized for user satisfaction even before launch. This focus on users, known as "UX design" or "user-centered design," emphasizes usability and accessibility.
UX significantly influences a product's success. It is essential during product design, applicable to household items, vehicles, or websites. User expectations and how well a product meets these expectations are crucial for a quality user experience, aligning with user-centered design. Beyond aesthetics, it's vital to prioritize users during product development.
Effective UX design aligns with both aesthetic and practical user expectations, addressing user needs. This varies by product. For websites, ease of navigation and content accessibility are vital. Clear contrasts, readable fonts, and structured text enhance user comprehension. Accessibility ensures users quickly find desired information, impacting both product and information-seeking experiences. In e-commerce, a seamless shopping process boosts user satisfaction and conversions.
Site performance also affects user satisfaction. Slow loading times and poor mobile optimization can detract from the user experience.
Usability is defined by its ISO standard as a product's efficiency, effectiveness, and satisfaction in use (DIN ISO 9241-11). In contrast, user experience encompasses users' perceptions and responses before, during, and after product use (DIN ISO 9241-210). The key difference is that usability focuses on the usage period, while user experience includes user expectations and their fulfillment, making usability a component of UX.
An exceptional user experience can positively influence a website's ranking in search results. Metrics like visit duration, return-to-SERP rate, and click-through rate are considered by search engines like Google, potentially affecting rankings.
