介紹

每個外部資源（字體、腳本、映像、API 端點）都需要網路連線。 DNS 解析、TCP 握手和 TLS 協商的開銷可能會導致頁面載入時間增加數百毫秒。 資源提示如 dns-prefetch 和 preconnect 讓您告訴瀏覽器在實際需要資源之前提前執行這些步驟。

Approaches to Improving Interaction to Next 疼痛t (INP)

Sat, 15 Mar 2025 00:00:00 +0900

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Core Web Vitals metrics, which measure the user experience of web pages, FID (First Input Delay) has officially been replaced by INP (Interaction to Next Paint).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 優化: Complete 2024 指南

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.
