Conduct a synthetic test that simulates a slow mobile phone on a typical network. Use tools like PageSpeed Insights and CrUX for real-user data, and Lighthouse or WebPageTest for lab tests. Prioritize high-impact, low-effort fixes such as optimizing images, server response times, and third-party scripts. Validate improvements using Real-User Monitoring (RUM) and assess whether a major rebuild is justified based on potential conversion gains and maintenance costs.<\/p>\n<h2>Key Metrics and Tools<\/h2>\n<ul>\n<li><strong>Core Web Vitals<\/strong>: Google highlights three metrics for user experience\u2014LCP, INP, and CLS. Recommended thresholds are LCP \u2264 2.5 seconds, INP \u2264 200 milliseconds, and CLS \u2264 0.1.<\/li>\n<li><strong>Data Sources<\/strong>: PageSpeed Insights and the Chrome UX Report (CrUX) provide real-user data, while Lighthouse and WebPageTest provide synthetic data, helping to pinpoint the causes.<\/li>\n<li><strong>Tools for Improvement<\/strong>: Use PageSpeed Insights for real-world data and lab recommendations, WebPageTest for reproducible tests, and Lighthouse for in-depth lab audits.<\/li>\n<\/ul>\n<h2>Identifying and Addressing Symptoms<\/h2>\n<ul>\n<li>Look for short mobile sessions and high bounce rates on landing pages.<\/li>\n<li>Identify high drop-off rates in conversion funnels, especially after landing pages.<\/li>\n<li>Note any discrepancies between lab tests and real-world user experiences.<\/li>\n<li>Fix visual issues such as layout shifts and unresponsive buttons.<\/li>\n<\/ul>\n<h2>Effective Measurement Techniques<\/h2>\n<p>Focus on primary metrics such as LCP, INP, and CLS, and supplement them with Time to First Byte (TTFB), First Contentful Paint (FCP), and Total Blocking Time (TBT).
