Optimizing Interaction to Next Paint (INP) for Your Website
2026-06-27 • 1 min read
Interaction to Next Paint (INP) measures user interface responsiveness, capturing the latency of click, tap, and keyboard inputs.
A high INP value indicates that page updates are blocked by long-running JavaScript execution tasks on the main thread.
Optimize INP by yielding execution to the browser using requestIdleCallback or splitting complex functions into microtasks.
Avoid blocking layout rendering during form submissions or modal transitions. Provide immediate visual feedback.
Improving interface responsiveness directly reduces site bounce rates and qualifies pages for core web vital ranking boosts.
