Core Web Vitals and SEO
Core Web Vitals are Google's way of measuring real-world user experience: how quickly a page shows its main content, how soon it responds to input, and how steady the layout stays while loading. They are a confirmed, if modest, ranking factor.
More importantly, they reflect how your visitors actually feel about your site, so improving them benefits both your rankings and your conversion rate at the same time.
The Three Metrics
Each vital measures a different part of the loading experience, and all three need attention.
Improving Your Scores
Most poor scores trace back to a few familiar culprits. Optimising images, reserving space for elements so the layout does not jump, and trimming heavy JavaScript typically move all three metrics in the right direction. We measure on real pages, fix the biggest issues first, then verify the gains with live data.
| Metric | Measures | Good score |
|---|---|---|
| LCP | Loading of main content | Under 2.5 seconds |
| INP | Responsiveness to input | Under 200 ms |
| CLS | Visual stability | Under 0.1 |
Frequently Asked Questions
How much do Core Web Vitals affect rankings?
They are a tie-breaker rather than the main factor. Great content still wins, but strong vitals give you the edge over a close rival.
How do we measure them?
We use the Core Web Vitals report in Search Console plus tools like PageSpeed Insights on real pages.
