Makes static sites on Cloudflare's edge fast for real users and proves it with field data - Core Web Vitals (LCP, INP, CLS) diagnosed by subpart and phase, ranked fixes for hero images, fonts, JavaScript, third parties and layout shift, edge caching, speculation rules and the back/forward cache, RUM and APM choices (RUMvision, Cloudflare Web Analytics, a free web-vitals beacon into Workers Analytics Engine, Workers Observability) with EU privacy, Lighthouse CI budgets, and a build plus live scanner. Use when a site is slow or feels slow; when LCP, INP or CLS fail in PageSpeed Insights, Lighthouse or Search Console; to improve a Lighthouse or PageSpeed score; when setting up real user monitoring, RUMvision, CrUX, synthetic checks or performance alerts; when adding a performance budget to CI; when a hero image, web font, cookie banner or third-party script slows a page; or to check whether a site is fast enough. Not for search rankings (search-visibility) or deployment (edge-hosting).
