PageSpeed

What is PageSpeed?

PageSpeed refers to a website’s loading speed. It is measured using PageSpeed Insights (Google), Lighthouse, WebPageTest, or the built-in Core Web Vitals measurement in Search Console. The most important metrics are LCP, INP, CLS, and Time to First Byte (TTFB). Typical optimization strategies for SMEs: modern image formats (AVIF/WebP), aggressive caching, reduced JavaScript, lean web fonts, and CDN usage. At Waterproof Web Wizard, we track PageSpeed by page type and optimize where loading patterns and business impact intersect, a fast “About” page is often less important than a fast product page.
