Introducing the Chrome User Experience Report
Monday, October 23, 2017
Chrome was founded to push the web forward, and a key part of that is enabling developers to improve their user experience. Although current tools allow developers to understand how real-world users experience their own sites, they have never provided insight into comparisons with other sites or macro user experience trends across the web. Following similar efforts like the
HTTPS Transparency Report
, today we’re making the
Chrome User Experience Report
available to encourage performance and user experience improvements across the web.
The report is a public dataset of key user experience metrics for top origins on the web. All performance data included in the report is from real-world conditions, aggregated from Chrome users who have opted-in to syncing their browsing history and have
usage statistic reporting enabled
. The initial release includes data from a sample of ten thousand origins and focuses on loading metrics, though we hope to expand coverage in future iterations. For full details on the dataset format, how to access it, and best practices for analysis, please see
our developer documentation
.
By querying the dataset, developers can understand how real Chrome users experience the web from the diverse set of hardware, software, and networks they use in the wild. Analyzing many origins on the web will help site developers and the web community understand where they are doing well, identify areas for improvement, and observe advancements in user experience over time.
We welcome
feedback
on the dataset’s format, metrics, dimensions, or any other ways to improve the report. We hope that this dataset will help the web community identify opportunities, record trends, and improve user experience on the web.
