HTTP Archive’s annual
state of the web report
Our mission is to combine the raw stats and trends of the HTTP Archive with the expertise of the web community. The Web Almanac is a comprehensive report on the state of the web, backed by real data and trusted web experts. The 2019 edition is comprised of 20 chapters spanning aspects of page content, user experience, publishing, and distribution.Start exploring
HTTP compression is a technique that allows you to encode information using fewer bits than the original representation. When used for delivering web content, it enables web servers to reduce the amount of data transmitted to clients. This increases the efficiency of the client’s available bandwidth, reduces page weight, and improves web performance.
The Web Almanac has been made possible by the hard work of the web community. 100 people have volunteered countless hours in the planning, research, writing and production phases of the 2019 Web Almanac.See the contributors
Unless otherwise noted, the metrics in all of the 20 chapters of the 2019 Web Almanac are sourced from the HTTP Archive dataset. HTTP Archive is a community-run project that has been tracking how the web is built since 2010. Using WebPageTest and Lighthouse under the hood, metadata about nearly 6 million websites are tested monthly and included in a public BigQuery database for analysis. The July 2019 dataset was used as the basis for the 2019 Web Almanac’s metrics. For more information, see the Methodology page.Learn about our Methodology
