Core Web Vitals and SEO
Why do Core Web Vitals matter?
Google uses Core Web Vitals as part of its page experience signals, so a slow page can cost you rankings as well as visitors.
The three Core Web Vitals
Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift measure loading, responsiveness and visual stability.
Lab data you can act on
Each test runs Google Lighthouse in Chrome and lists the changes that would make the page faster.

What page speed metrics matter, and why
Your speed test surfaces several numbers. The ones that move SEO + user experience:
Largest Contentful Paint (LCP)
How fast the main content of your page loads. Good: under 2.5 seconds. Slow LCP correlates with bounce rate and lost conversions.
Cumulative Layout Shift (CLS)
Measures unexpected visual shifts during page load, buttons jumping, content moving as images arrive. Good: under 0.1.
Interaction to Next Paint (INP)
Measures responsiveness, how quickly the page reacts to clicks, taps, and key presses. Replaced FID in March 2024. Good: under 200 ms.
Time to First Byte (TTFB)
How quickly your server responds to the request. Slow TTFB caps how fast LCP can ever be. Good: under 800 ms.
Website speed testing FAQ
What is a website speed test?
A website speed test measures how fast a page loads and becomes interactive from a real user's perspective. It typically runs Lighthouse against your URL from a controlled browser, captures Core Web Vitals (LCP, INP, CLS), and surfaces opportunities to make the page faster.
What's a good page speed score?
Lighthouse Performance score of 90 or higher is good. Core Web Vitals: LCP under 2.5 seconds, INP under 200 ms, CLS under 0.1. Sites passing these thresholds tend to rank higher and convert better than those that don't.
How often should I test my website's speed?
For static marketing pages, weekly is enough. For frequently-changing apps, run a check on every deploy via CI. LoadFocus monitoring runs the test on a schedule and alerts on regressions, so you don't have to remember.
What's the difference between lab data and field data?
Lab data (Lighthouse, LoadFocus) measures performance in a controlled environment, same device, same network. Field data (Chrome User Experience Report) is what real users actually experience. Lab catches regressions before deploy; field tells the truth about your real-user mix.
Why does my site fail Core Web Vitals?
The usual suspects: oversized images, render-blocking JavaScript, unsized images causing layout shift, slow server response (TTFB), and heavy third-party scripts. The speed test report tells you exactly which apply to your page.
Does page speed affect Google rankings?
Yes. Core Web Vitals are part of Google's page experience signal. Pages passing CWV thresholds get a ranking advantage in competitive queries. They also have lower bounce rates and higher conversion, so the SEO and UX wins compound.
