Key takeaways
- A good LCP is 2.5 seconds or less, a good INP is 200 milliseconds or less, and a good CLS is 0.1 or less
- web.dev says to measure at the 75th percentile of page loads, split by mobile and desktop
- Poor starts above 4.0 seconds for LCP, 500 milliseconds for INP and 0.25 for CLS
- 3 free tools show real-user data: PageSpeed Insights, the Chrome User Experience Report and Search Console
- Google says it highly recommends good Core Web Vitals for success with Search
According to web.dev, a page has good Core Web Vitals when its Largest Contentful Paint is 2.5 seconds or less, its Interaction to Next Paint is 200 milliseconds or less, and its Cumulative Layout Shift is 0.1 or less, measured at the 75th percentile of page loads.
If you run a local business site in Rockingham, Baldivis, Mandurah or Cockburn, those three numbers are your speed test. They measure loading, response to taps and clicks, and whether the page jumps around. This guide gives you the pass marks, the poor marks, and where to look.
The pass marks
| Metric | Measures | Good | Poor |
|---|---|---|---|
| Largest Contentful Paint (LCP) | Loading | 2.5 seconds or less | Over 4.0 seconds |
| Interaction to Next Paint (INP) | Responsiveness | 200 milliseconds or less | Over 500 milliseconds |
| Cumulative Layout Shift (CLS) | Visual stability | 0.1 or less | Over 0.25 |
Anything between good and poor “needs improvement”.
Takeaway: three numbers, one test. Pass all three at the 75th percentile and your page counts as good.
Why the 75th percentile
web.dev says a good threshold to measure is the 75th percentile of page loads, segmented across mobile and desktop. The point is to make sure most of your visitors get the good experience, including people on slower phones and patchy connections.
Where to check your own site
web.dev lists these field tools, which use real visitor data:
- PageSpeed Insights. Paste your address, read the Core Web Vitals box at the top.
- Chrome User Experience Report. The dataset behind the other tools.
- Search Console. The Core Web Vitals report, if your site is verified.
If a tool shows no field data for your page, run a lab test and treat the result as a guide, not a verdict.
What Google says about ranking
Google’s Search Central page says it “highly recommends” site owners achieve good Core Web Vitals “for success with Search” and a great user experience. It says this, along with other page experience aspects, aligns with what its core ranking systems seek to reward. It does not claim Core Web Vitals decide your position on their own, and we will not either.
What to fix first
Each metric has its own cause and its own fix. We cover them one by one:
