How fast your website feels on a phone, and how to make it faster. We explain Google PageSpeed scores and Core Web Vitals — LCP, CLS and INP — in simple words. Articles show which images, scripts, fonts and server settings slow pages down the most. Each guide ranks fixes by impact, so you start with the change that saves the most seconds.
