Quick answer: Google updated its page experience documentation on September 25, 2026 to reference Core Web Vitals ad-related metrics now available through the Chrome UX Report (CrUX). Google explicitly clarified that these ad metrics are informational only and do not function as a ranking factor.
What happened
The update expands what CrUX reports on to include metrics tied specifically to how ads affect a page’s loading and interactivity experience. This gives site owners running ads more visibility into how ad-related scripts and content might be dragging down Core Web Vitals scores, separate from the page’s core content.
Why it matters
Even though Google was explicit that these new ad metrics don’t factor into rankings, they’re still useful diagnostic data. Sites that rely heavily on ad revenue can now see more precisely whether ad-serving code is contributing to slow load times or layout shifts, which do roll up into the Core Web Vitals metrics that have mattered for search and user experience for years.
