What is Page Speed?
Page speed refers to the time needed until a web page is fully loaded. It has been an official Google ranking factor since 2010 and part of Core Web Vitals since 2021. Important metrics: Time to First Byte (TTFB), First Contentful Paint (FCP), Largest Contentful Paint (LCP), Time to Interactive (TTI). Optimization options: compress images (WebP format), use browser caching, minify JavaScript and CSS, use CDN, inline critical CSS, lazy loading for images, improve server response time. Tools: Google PageSpeed Insights, GTmetrix, WebPageTest. Goal: LCP under 2.5 seconds.
