Website speed is critical for both SEO and user experience. A slow-loading website increases bounce rates, negatively impacting rankings on search engines like Google. Users expect a website to load within three seconds; any delay can reduce conversions. Speed optimization techniques include image compression, browser caching, and using a content delivery network (CDN). Google’s Core Web Vitals, which focus on loading performance and interactivity, directly affect search rankings. A faster website leads to higher engagement and better user retention.
