The Standardized User Experience Percentile Rank Questionnaire (SUPR-Q) is an 8-item index that measures the quality of a website user experience. It goes beyond simple usability to capture Usability, Trust, Appearance, and Loyalty.
Use SUPR-Q when you need a high-level view of how your brand's digital presence is perceived compared to competitors. Because it includes trust and loyalty metrics, it is particularly useful for e-commerce and banking websites where user confidence is paramount.
