We think these are some of the key measures of ad experiences and are excited to share this data. It's difficult to measure these types of metrics given technical constrains on the web platform, so CrUX is in a unique position to publish this data. 3/8

cruxvis.withgoogle.comCrUX VisCrUX Vis is a tool by the Chrome team to help you explore the Chrome User Experience Report (CrUX) data with visualizations and helpful links to articles, for a particular web page or origin.

The metrics are available in the CrUX API and the CrUX History API today and you can view these metrics for sites with third-party ads in CrUX Vis: cruxvis.withgoogle.com We're working on adding them to CrUX BigQuery dataset. 4/8

Will this data get integrated into PageSpeed Insights and the PageSpeed API?

No plans for PSI integration at the moment.

We've heard from a large cross-section of ad ecosystem stakeholders that these metrics could enhance how they value ad opportunities and make ad product decisions. We're encouraged by this as we think users ultimately benefit from more collective attention paid to tuning web ad experiences. 5/8

While inspired by Core Web Vitals, which help provide visibility into websites' speed, responsiveness and visual stability, CrUX ad metrics are not part of Core Web Vitals and don't have suggested targets or thresholds. 6/8

I couldn't immediately see a way to view these on mobile, but switching to desktop mode does give me the side navigation.
