Performance: Core Web Vitals

Real visitor data (RUM) on load time, LCP, INP and CLS, with percentiles and the slowest pages.

What it is

Core Web Vitals shows how fast your site really is for your visitors, using data collected from real visits (Real User Monitoring). These are the same metrics Google uses to evaluate page experience.

To open it: Performance, then Core Web Vitals. The item appears only when the Tuurbo CDN is active on your site.

Choosing the period

Use the period selector: 24 hours, 3 days, 7 days, 15 days, 30 days, or Custom to choose start and end dates (within the last 30 days).

What you see

Page Load Time, Visits and Page Views, with the change compared to the previous period.
A block for each metric:
- LCP (Largest Contentful Paint): how long the main content takes to appear.
- INP (Interaction to Next Paint): how quickly the page responds to clicks and taps.
- CLS (Cumulative Layout Shift): how much the layout moves while loading.
For each metric: the share of visits rated Good, Needs improvement and Poor, the P50, P75, P90 and P99 values, and a table of pages (use Show all to see the full list). LCP also has a chart over time.

P75 is the value Google looks at: 75% of visits are equal to or better than this value.

Empty state

If you see "No analytics data available for this period", data has not been collected yet: it appears automatically as soon as the site receives traffic.

Tips

Start from the pages with the worst values and check the optimizations in Automations.
Compare periods before and after a change to see its effect.
