Introduction

In Google’s Core Web Vitals metrics, which measure the user experience of web pages, FID (First Input Delay) has officially been replaced by INP (Interaction to Next Paint).

While FID only measured the response speed of the very first user interaction, INP evaluates the responsiveness of all clicks, taps, and keyboard inputs across the entire lifecycle of the page visit. It logs the delay between an interaction and the subsequent visual update (the “Next Paint”).

Core Web Vitals (CWV) are the set of user-centric performance metrics that Google uses to measure real-world experience on the web. In March 2024, Google replaced First Input Delay (FID) with Interaction to Next Paint (INP), making it critical to understand all three metrics: Largest Contentful Paint (LCP), INP, and Cumulative Layout Shift (CLS). This guide covers every aspect of optimizing your site for good CWV scores.

Understanding Core Web Vitals in 2024

The three CWV metrics measure distinct aspects of user experience. LCP tracks loading performance — how quickly the main content appears. INP measures interactivity — how responsive the page feels when users click, tap, or type. CLS quantifies visual stability — how much the layout shifts unexpectedly during load.
