Google Core Web Vitals Update: Introduction of Interaction to Next Paint (INP)

Google is set to revolutionize its Core Web Vitals by introducing the Interaction to Next Paint (INP) metric on March 12, 2024. This new metric will replace the First Input Delay (FID), marking a significant shift in how website responsiveness and user experience are measured. The introduction of INP reflects Google’s commitment to enhancing web usability and providing developers with more accurate tools for assessing interaction quality.

Key Points About INP:

  • Introduction Date: INP will officially become a Core Web Vital on March 12, 2024, replacing FID.
  • Purpose: INP aims to measure the responsiveness of a webpage more comprehensively by considering the time from when a user interacts with the page to when the browser renders the change on the screen.
  • Why INP: FID measured the delay for the first input, but INP provides a broader assessment by considering all interactions over the page’s lifetime, offering a more detailed view of the user experience.
  • Preparation: Developers are encouraged to evaluate their sites’ current INP performance using tools like PageSpeed Insights and the Chrome User Experience Report. Optimizations may involve addressing long JavaScript tasks, reducing input delay, and simplifying DOM structure.

Bullet Points Summary:

  • March 12, 2024, Launch: INP becomes a Core Web Vital, replacing FID.
  • Enhanced Measurement: Unlike FID, INP assesses all interactions, not just the first, for a more comprehensive understanding of a page’s responsiveness.
  • Developer Action: Check INP scores using Google’s recommended tools and optimize as necessary to meet the “good” INP threshold.
  • Optimization Guidance: Google provides detailed advice on diagnosing and improving INP, including optimizing long tasks, input delay, and minimizing DOM size.

The shift to INP underscores the importance of building web experiences that are not just fast but also reliably responsive to user interactions. As the web development community prepares for this change, focusing on INP optimization will become crucial for maintaining and improving search rankings and user engagement.

For an in-depth understanding of the INP metric and its implications, developers and website owners should review Google’s official documentation and related resources on web.dev and Search Engine Journal. These sources provide comprehensive insights into preparing for the transition to INP, ensuring websites are optimized for the best possible user experience.
