Page Speed
Page speed is a measurement of how quickly the content on a web page loads and becomes interactive. It encompasses multiple metrics including Time to First Byte (TTFB), Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), collectively known as Core Web Vitals.
Page speed directly affects three critical outcomes: search engine rankings, user experience, and conversion rates. Google has confirmed that Core Web Vitals are a ranking factor, so slow pages lose organic visibility. Visitors who encounter slow-loading pages bounce at dramatically higher rates. And those who do stay convert at lower rates due to frustration and reduced trust. For Shopify stores where every millisecond counts, page speed optimization delivers compounding returns across SEO, engagement, and revenue.
