⚡ Page Speed Monitoring

Analyze your website's performance and Core Web Vitals for an optimal user experience with modern INP metrics.

📊 Overview

Page Speed monitoring uses the Google PageSpeed Insights API to analyze your website's performance and Core Web Vitals. It gives you insight into how users experience your site on both mobile devices and desktop.

Important update: As of March 2024, Google replaced FID (First Input Delay) with INP (Interaction to Next Paint) as a Core Web Vital. StackWatch uses the latest INP metric.

🎯 Core Web Vitals
LCP - Largest Contentful Paint

Measures the load time of the largest visible element on the page.

• Good: ≤ 2.5 seconds
• Needs improvement: 2.5-4.0 seconds
• Poor: > 4.0 seconds
FCP - First Contentful Paint

Measures the time until the first visible content appears on the page.

• Good: ≤ 1.8 seconds
• Needs improvement: 1.8-3.0 seconds
• Poor: > 3.0 seconds
CLS - Cumulative Layout Shift

Measures visual stability — how much the content shifts around.

• Good: ≤ 0.1
• Needs improvement: 0.1-0.25
• Poor: > 0.25
INP - Interaction to Next Paint ⚡ NEW!

Measures responsiveness — the time from a user interaction to the next visual update.

• Good: ≤ 200 milliseconds
• Needs improvement: 200-500 milliseconds
• Poor: > 500 milliseconds
TTFB - Time to First Byte

Measures server time — how quickly the server responds to requests.

• Good: ≤ 800 milliseconds • Needs improvement: 800-1800 milliseconds • Poor: > 1800 milliseconds
