What is Interaction to Next Paint?
Interaction to Next Paint (INP) is a Core Web Vitals metric that measures the time from a user interaction — click, tap or keypress — to the next visual update on screen. It reflects how responsive a page feels during real use.
Why INP matters
INP replaced First Input Delay (FID) as a Core Web Vital in March 2024. Slow interactions frustrate users and hurt the page experience signal. A page that feels sluggish to tap or click will rank below a responsive competitor.
How to improve INP
- Minimize long-running JavaScript tasks.
- Break up heavy work and defer non-critical scripts.
- Reduce DOM size and layout complexity.
- Optimize event handlers and animations.
Target
Google’s threshold for ‘good’ INP is under 200 milliseconds.
