Google has added four experimental ad experience metrics to the Chrome User Experience Report (CrUX). The new data aims to show how advertising affects the experience of real users on websites.
The metrics measure factors such as the number of ads, the space they occupy, and the CPU and network resources they use. The data could help publishers understand how ads affect site performance and user experience.
For now, Google has not indicated that these metrics are used as ranking factors. However, SEOs and website owners may monitor them as Google continues to expand the data available through CrUX.
The new metrics provide data on four areas of ad experience:
Together, these measurements give publishers more visibility into the technical impact of advertising on web pages.
CrUX is Google's field data platform based on real-world browsing experiences. It collects anonymised performance data from Chrome users who have opted into sharing their usage statistics.
The dataset covers Chrome users across Android, ChromeOS, Linux, macOS, and Windows. Chrome on iOS is not included in the dataset.
The field data from CrUX is also used in tools such as Google PageSpeed Insights to report real-user Core Web Vitals.
Google is making the new ad experience data available through the CrUX API and CrUX History API. The metrics can also be viewed through the Ad panel in Chrome DevTools.
Google said the data will also be added to the CrUX BigQuery dataset in the future. This could allow publishers, developers, and SEOs to conduct broader analysis of advertising and user experience across websites.
