CrUX Field Data Available
The Chrome User Experience Report (CrUX) only includes sites with enough real-world Chrome traffic to produce stable field-level Core Web Vitals. Whether your site appears in CrUX is itself a traction signal — Google has decided you have a real audience. SaaSalyst reads the PageSpeed Insights response to detect whether CrUX data was returned for your origin.
What SaaSalyst Checks
SaaSalyst inspects the PageSpeed Insights API response for a populated loadingExperience.metrics block. Presence of that block means Google's CrUX dataset has enough real-world Chrome traffic to report field-level performance for your origin. Absence means your site has not crossed CrUX's traffic threshold yet — the check fails softly at low severity. If the PSI call itself fails, the check is reported as warn rather than fail to avoid false signals.
Why This Matters
CrUX coverage is a public, Google-maintained traction signal. Buyers, analysts, and partners can verify it independently, and it correlates with having a real user base rather than a brand-new storefront.
For early-stage SaaS, absence of CrUX data is informational rather than a defect — that's why SaaSalyst scores this at low severity. But as you pursue distribution, seeing your site enter CrUX coverage is a meaningful milestone: it means your product is getting enough real-world usage that Google reports on it.

How to Fix It
- Drive sustained Chrome user traffic through your usual acquisition channels — organic search, paid, social, partnerships.
- Verify your site is not blocked from Chrome crash/metrics reporting (no X-Robots-Tag directives or firewall rules that strip user visits).
- Check back after 28 days — CrUX uses a rolling 28-day aggregate; new traction takes time to show up.
- Use Google Search Console's Core Web Vitals report to verify whether your origin is CrUX-covered once you believe traction is sufficient.
Frequently Asked Questions
How much traffic do I need to appear in CrUX?
Google does not publish a hard threshold, but community analysis of the Chrome UX Report suggests roughly 1,000+ monthly Chrome page visits per origin. SaaSalyst does not estimate the number directly — it just reports whether CrUX data is present.
Why is this check severity 'low' instead of higher?
Brand-new sites legitimately don't have CrUX data yet. SaaSalyst uses low severity so this traction signal informs your Business Readiness Score without dominating it for early-stage products.
Does this check make an extra API call?
No. SaaSalyst reuses the existing PageSpeed Insights response that powers the other Performance checks. The CrUX data is always in that response when Google has enough field data to report.
