Review Web Vitals

Inspect LCP, CLS, INP, FCP and TTFB measurements from the full tracker script.

Use Web Vitals to review real-user loading, stability and responsiveness measurements.

  1. In Site settings → Tracking, enable Track Web Vitals and save the settings.

  2. Confirm the site uses the full tracker script, then wait for visitors to load and leave pages.

  3. Open Web Vitals from the sidebar.

  4. Read the Largest Contentful Paint, Cumulative Layout Shift, Interaction to Next Paint, First Contentful Paint and Time to First Byte cards. Each card shows p75, its rating and sample distribution.

  5. In Daily trend, switch among LCP, CLS, INP, FCP and TTFB. Use Breakdown to group results by Page, Device, Country, or Browser.

What you should see: the metric cards, daily percentile trend and selected breakdown contain collected samples.

FCP is rated good up to 1.8 s and poor above 3.0 s. TTFB is rated good up to 0.8 s and poor above 1.8 s. TTFB is read on the initial page load, not on in-app navigations.
