It’s critically important to stop optimizing web pages for $1,200.00 smartphones with ultra-fast internet connections because the vast majority of internet users don’t live in that world, and the energy required to power that world is unsustainable.

Methodology
Unless otherwise noted, the metrics in all of the 24 chapters of the 2021 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 8.2 million websites are tested monthly and included in a public BigQuery database for analysis. The July 2021 dataset was used as the basis for the 2021 Web Almanac’s metrics. For more information, see the Methodology page.
