Understand and optimize the three key metrics that Google uses to measure user experience and determine search rankings.
Measures loading performance. Aim for under 2.5 seconds for a good user experience.
Measures visual stability. Keep layout shifts under 0.1 for optimal user experience.
Measures interactivity. Target under 200ms for responsive user interactions.
If you’re not sure where to begin, follow this quick workflow. It keeps you focused on changes that actually improve the experience for real users.
Run a speed test to identify which metric is the bottleneck (loading, responsiveness, or visual stability). Save your baseline so you can verify improvements later.
Run the Speed Test →Pick one area to improve and ship a small change. For most sites, the fastest wins are images, caching, and reducing heavy scripts.
Re-run the test after each meaningful change. Once you’re happy with your results, monitor key pages over time so performance doesn’t slowly drift.
Tip: test both mobile and desktop, and run at least two checks to avoid one-off network noise.

Start with the biggest issue from your speed test. If your page loads slowly, focus on LCP and images. If it feels laggy, focus on INP and heavy JavaScript. If things jump around, focus on CLS.
Usually no. Small, targeted improvements—like compressing a hero image, caching pages, or deferring a script— can make a noticeable difference without a redesign.
Core Web Vitals are a good starting point: LCP (loading), INP (responsiveness), and CLS (stability). Supporting metrics like TTFB and FCP help explain root causes.
Make one change at a time and re-test. Avoid “mystery optimizations” that rewrite your site in ways you can’t control. Use tools that let you turn features on/off and verify impact.
Use the guides to understand the “why”, then pick a tool that matches your setup. See Best Tools and the Core Web Vitals overview.
Confirm on both mobile and desktop, test multiple runs, and (if possible) compare with real-user analytics. The goal isn’t “perfect scores”—it’s a faster, smoother experience for visitors.
