Google open-sourced today some of Chrome's usage metrics in an attempt to help developers create better websites.

The published data contains anonymized metrics from Chrome users who enabled the browser's usage statistic reporting feature, but also data from users who opted-in to sync browsing history.

More data to be released each month

Google plans to release more Chrome metrics data each month, as part of a project named the Chrome User Experience Report.

The first Chrome User Experience Report contains data from ten thousand websites (origin URLs) and is focused on loading metrics such as First Paint, First Contentful Paint, Connection Type, Device Type, and others.

Developers can study these statistics and see how a website designed in a certain way loads in Chrome, what are the best technologies for building modern websites, and what are the average loading metrics across the web.

The data is not downloadable. Developers can access and query the data using a Google account and a Google Cloud Project. Instructions are available here and here.

Google announced the Chrome User Experience Report today at the Chrome Dev Summit 2017, a conference taking place in San Francisco (live stream here).

HTTPS traffic has grown since last year

The Chrome User Experience Report announcement comes after last week Google released an update to its "HTTPS encryption on the web" section, part of its Transparency Report.

According to Google, 80% of all Google Chrome traffic on Chrome OS is over HTTPS, 75% of all Google Chrome traffic on macOS is over HTTPS, 67% on Windows, 65% on Android, and 61% on Linux. All numbers are up compared to the previous years.

In addition, Google said that 89% of all traffic landing on Google domains is now encrypted, up from 85% last year. Of all products, Google Drive and Gmail are 100% HTTPS, while YouTube is 99% and Google Calendar 98%.
