What it means
It evaluates how quickly the interface responds to clicks, taps and keyboard input throughout a real visit.
Term in plain language
INP
A field metric for the delay between user interactions and the page's next visual response.
Why it matters
A high INP points to heavy handlers or long tasks that make a functional control feel frozen.
Example
Filter work is split into shorter tasks so the selected option appears promptly even on a slower phone.
