Core Web Vitals from your real visitors
See the performance your actual visitors experience, on their real phones and networks. This is the speed Google measures for search ranking, and it is not something a single lab test can tell you.
These are the thresholds Google scores for ranking. VeritaMetrics reports the real 75th percentile your visitors experience, not a one-off lab test.
What this means for your search ranking
Google uses page experience, including Core Web Vitals, in its ranking systems. In plain terms: when two pages are about equally relevant, the faster one can rank higher, and a slow page can quietly cost you visitors.
Faster pages can rank higher
Core Web Vitals are one of the signals Google uses to rank pages. Good scores help you show up in search for the terms you care about.
Slow pages lose visitors first
Google found that more than half of mobile visits are abandoned when a page takes longer than three seconds to load. You lose the reader before they ever see the content.
Real visitors are what Google scores
Google ranks on the speed your actual visitors get, not a one-off lab test. VeritaMetrics reports that real-world number, so you watch the same thing Google does.
The numbers back it up: in a controlled test, Vodafone made its main content load 31% faster and saw an 8% lift in sales.
The three metrics we measure
Largest Contentful Paint
How fast the main content of the page loads.
Good under 2.5 s
Interaction to Next Paint
How quickly the page responds when a visitor interacts with it.
Good under 200 ms
Cumulative Layout Shift
How much the layout moves around while the page loads.
Good under 0.1
Field data, not a lab test
A lab test (like Lighthouse)
Loads your page once, on one simulated device, over one throttled network, with nobody interacting. Useful for debugging a page while you build it, but it cannot tell you what a real visitor on a three-year-old phone actually experiences, and it cannot measure INP or layout shifts that happen as people scroll.
Field data (what we collect)
Measured from your real visitors, on their real devices and networks, across whole sessions. This is the data Google ranks on, and it captures the visitors a lab run never sees. You get the score for the slower end of your visitors (the 75th percentile, the cut Google uses), updated as visits come in.
Turning it on
Web Vitals is off by default, so it only runs when you ask for it. Add one attribute to your tracking script tag:
<script
defer
data-site-id="YOUR_SITE_ID"
data-web-vitals="true"
src="https://www.veritametrics.com/tracker.js"></script>Web Vitals is available on the Professional plan and up. The rest of VeritaMetrics stays the same: cookieless, no consent banner, and a script that sets no cookies.
Measure what your visitors actually experience
