Core Web Vitals
analytics
Track real user performance metrics from actual visitors. See LCP, INP, CLS, FCP, and TTFB broken down by page, country, and device.
No credit card required
Real user metrics. Data from actual visitors, not synthetic lab tests.
Breakdown by dimension. Filter by page, country, device, browser, and more.
Actionable insights. Find slow pages and devices that need optimization.
Real users, not simulations.
Beyond Lighthouse.
Lighthouse and PageSpeed Insights run lab tests in controlled environments. We measure what your actual visitors experience.
Field data, not lab data. Lighthouse runs simulations. We measure what your actual visitors experience on their real devices.
Instant, not weekly. Google's CrUX data updates once a week. We stream metrics the moment they happen.
Every visitor counts. Some tools sample a percentage of traffic. We capture performance data from every single pageview.
Every metric that matters.
Tracked automatically.
We capture all Core Web Vitals plus additional metrics that help you understand real user experience.
Experience Score. A weighted composite of all vitals into a single 0-100 number.
Largest Contentful Paint. How long until the main content is visible to your visitors.
Interaction to Next Paint. How quickly your site responds to clicks, taps, and key presses.
Cumulative Layout Shift. How much the page layout shifts unexpectedly while loading.
First Contentful Paint. When the first piece of content appears on screen for visitors.
Time to First Byte. How long until the browser receives the first byte from your server.
Speed affects everything.
Rankings, revenue, retention.
Core Web Vitals aren't just technical metrics. They directly impact your search rankings, conversion rates, and user satisfaction.
Google ranking factor. Core Web Vitals are part of Google's page experience signals. Faster pages can outrank slower competitors.
Conversions depend on speed. Every 100ms of latency costs. Slow pages lose visitors before they even see your content.
Users feel the difference. Fast sites feel professional. Slow sites feel broken. Performance shapes how people perceive your brand.
Find what's slow.
And fix it.
Break down performance by page, country, device, browser, and more. Identify exactly where visitors are having problems.
Experience Score
Track your Experience Score over time
Your Experience Score combines all Core Web Vitals into a single number. Watch it improve as you optimize, or catch regressions before they affect users.
Identify your best performing pages
See which pages deliver the best experience. Learn from what's working and apply those patterns across your site.
Find pages that need work
Quickly surface pages with poor performance. Deploy fixes and watch your scores improve in realtime as new data flows in.
Performance data.
Not personal data.
We measure how fast your site loads without tracking who's loading it. No cookies, no personal data, no consent banners.
