Website speed is still a performance gap, not a solved problem. In 2023 CrUX data, only 23% of origin pages pass all Core Web Vitals thresholds, while mobile users are even less forgiving since 53% abandon sites that take longer than 3 seconds to load. When poor vitals can correlate with up to an 11.5% drop in pageviews and slower rankings, the tradeoff becomes impossible to ignore.
