CrUX Monitoring
Catch Core Web Vitals drops in CrUX the week they happen – before rankings follow
The Chrome User Experience Report (CrUX) is Google's official dataset for Core Web Vitals. It's what Google actually uses to assess your site for page experience ranking signals. We pull this data automatically so you always know where you stand – before your rankings are affected.
- Official Google Data
- Origin & URL-Level Tracking
- Mobile vs Desktop Split
- Weekly Updates

Your rankings dropped, but you don't know why
Google's Core Web Vitals are ranking signals. If your CrUX data shows poor performance, your search visibility suffers – often before you even notice.
Google Search Console only shows limited CrUX data with delays
You don't know if your Core Web Vitals are passing or failing until rankings drop
PageSpeed Insights gives you a snapshot, not a trend over time
You can't tell which specific URLs are dragging down your origin-level performance
Mobile and desktop performance often differs significantly, but tracking both is tedious
CrUX updates weekly, but you're only checking monthly
The official Google Core Web Vitals data
Track LCP, INP, CLS, and TTFB from the Chrome User Experience Report. See mobile vs desktop performance and historical trends.
Official Google Data
This is the same Core Web Vitals data that Google uses to evaluate your site for search rankings. No proxies, no estimates – the real numbers that matter for SEO.
Origin & URL-Level Tracking
Monitor your overall domain performance and drill down to individual URLs. Some pages might be passing while others fail – see exactly which ones need attention.
Mobile vs Desktop Split
Google evaluates mobile and desktop separately. Performance often differs between devices – track both and catch device-specific issues.
Weekly Updates
CrUX data updates weekly with a 28-day rolling window. We pull the latest data automatically so you're always seeing current information.
Threshold Monitoring
Get alerts when your Core Web Vitals cross from "Good" to "Needs Improvement" or "Poor", so you know when your SEO might be at risk.
Historical Trending
See how your Core Web Vitals have evolved over time. Correlate changes with deployments, traffic patterns, or Google algorithm updates.
Performance Context
Understand where your Core Web Vitals stand against Google's thresholds. See exactly where you need to improve to achieve "Good" ratings.
