Most common questions
What is Interaction to Next Paint (INP)?
INP measures how long it takes for a page to visually respond after a user interaction, like a click or key press. It uses real-user monitoring and reflects how quickly your site reacts to input, making the INP score a key metric for user experience and Core Web Vitals.
What is considered a good INP score?
A good INP score is under 200 milliseconds, meaning interactions feel instant. Scores between 200–500 ms indicate room for improvement, while anything above 500 ms suggests poor INP and noticeable delays that may frustrate users. Avoid high INP to retain users.
Why does my INP vary across sessions or users?
INP depends on real-world conditions like device performance, network latency, and main-thread activity. Real-user monitoring captures the specific delays different people face on their devices. A user on a low-end device or with background tasks competing for resources may experience slower INP, even on an optimized site. The INP metric often shifts based on who is visiting your site.
How can I improve my INP?
To improve INP, reduce the JavaScript and main-thread work that delays the browser’s response to user interactions. This usually means limiting blocking scripts, deferring non-critical code, and prioritizing interaction readiness. Uxify’s INProve helps by automatically breaking up blocking scripts so interactions can be handled first, improving responsiveness without major manual rewrites.
