Website Audits
The ECOS Web Audit is an online tool for evaluating websites based on efficiency, sustainability, openness, and security.
The results highlight potential for optimization, while global benchmarks allow individual findings to be compared and contextualized.
The evaluation approach is inspired by the Web Sustainability Guidelines (WSG) and the Sustainable Web Manifesto. Core components are derived from Google's Web Vitals framework and the PageSpeed Insights API. The sustainability assessment is based on the API and framework provided by the Green Web Foundation.
