Interaction to Next Paint (INP)

Interaction to Next Paint (INP) is a Core Web Vital metric that measures responsiveness. INP measures the time from when a user interacts with the page (like a click or keypress) until the next visual update is shown on screen. It evaluates the entire duration of the interaction, including input delay, processing time, and presentation delay. A low INP score (good responsiveness) is important for a smooth user experience.
