    Why this matters

    INP is a Core Web Vital that quantifies page responsiveness; optimizing it improves user experience and search ranking.

    A STARTING-POINT EXAMPLE

    Hypothetical standard operating procedure

    Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.

    1. Use tools like Search Console Core Web Vitals report or PageSpeed Insights to measure INP on key pages.
    2. Identify interactions causing high INP, such as heavy scripting or event handlers.
    3. Prioritize reducing main thread blocking time and optimizing input event handling.
    4. Apply code-splitting and defer non-critical JavaScript to improve responsiveness.
    5. Re-measure INP after changes to verify improvements and maintain under 200 milliseconds.

    Watch for

    Ignoring INP can cause unnoticed user interaction delays, harming usability and SEO.

    Definition of done

    Measured INP is consistently below 200 milliseconds on target pages.
