Interaction to Next Paint (INP) measures the responsiveness of a page to user interactions (clicks, taps, key presses) by tracking the time from the interaction to the next visual update. It replaced FID (First Input Delay) as a Core Web Vital in March 2024. Target: under 200ms.
Why INP (Interaction to Next Paint) matters for SEO
INP measures how responsive your page feels throughout the entire user session, not just the first interaction. High INP (over 200ms) means the page feels sluggish and unresponsive, increasing bounce rate and reducing engagement signals.
