Frequently Asked Questions
How to interpret page vs origin comparisons and when to use this diagnostic tool.
- What does 'origin' mean in CrUX?
- In the Chrome User Experience Report, 'origin' refers to the aggregate performance data for an entire domain (e.g., all pages on example.com). It represents the combined experience of all Chrome users across every page on that site.
- When is a page worse than the origin?
- When a page's P75 metric is higher (slower) than the origin's, it means that specific page underperforms relative to the site average. This usually indicates a page-specific issue — heavy images, slow third-party scripts, or unoptimized layout unique to that page.
- When is a page better than the origin?
- When a page's metrics are faster than the origin average, it means the page is not the bottleneck. Other pages on the site are likely dragging down the overall score. This is useful for identifying which pages need attention and which are already optimized.
- How is this different from Compare URLs?
- Compare URLs benchmarks up to 5 arbitrary URLs against each other — different sites, different pages. Page vs Origin specifically compares one page against its own site-wide baseline, which is a diagnostic tool for isolating page-level vs sitewide issues.
- What if the page and origin have similar metrics?
- Similar metrics between a page and its origin usually indicate a sitewide or systemic issue — server configuration, shared JavaScript bundles, CDN setup, or CMS-level problems that affect all pages equally. Fixing the page alone won't help; you need to address the root cause across the site.
- How is the origin URL detected?
- The origin is automatically extracted from the URL you enter. For example, if you enter 'example.com/pricing', the origin becomes 'example.com'. Both the page and origin data come from the same CrUX dataset and form factor, ensuring an apples-to-apples comparison.
