Summary

In July 2022, João Sousa Botto discussed the benefits of Signed Exchanges (SXG), a web platform specification that allows deterministic verification and faster serving of cached website versions. Google's experiments have shown an average reduction in Largest Contentful Paint (LCP) by 300ms to 400ms with SXG-enabled prefetches, leading to improved SEO and lower bounce rates. Cloudflare's Automatic Signed Exchanges simplifies the setup process for users. Real-world data from 500 sites showed that 85% experienced LCP improvements, while 78% saw First Contentful Paint (FCP) enhancements and 98% had Time to First Byte (TTFB) improvements. Overall, customers witnessed a median improvement of over 20% in these metrics. SXG is now supported by Chromium-based desktop browsers, including Chrome, Edge, and Opera, potentially doubling its coverage for site visits.
