Demystifying Speed Tooling
summary
A practical blueprint lists 15 actions and ships concrete tooling: Lighthouse 5.0 with Stack Packs (WordPress first) and a refreshed UI, PageSpeed Insights (lab+CrUX), and a new Search Console Speed Report (beta) that groups pages and flags 4,000 slow / 33,000 average / 800 fast URLs on the developer site example. Claims include measurable business impact—Pinterest sees a 44% revenue uplift—and lab + field monitoring via Firebase RUM and Lighthouse CI plus an element-timing origin trial for custom metrics.
