Unless otherwise noted, the metrics in all of the 16 chapters of the 2025 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 over 16 million websites are tested monthly and included in a public BigQuery database for analysis. The July 2025 dataset was used as the basis for the 2025 Web Almanac’s metrics. For more information, see the Methodology page.
