Focus your optimization efforts on these key metrics:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Largest Contentful Paint (LCP):<\/strong> When the main content becomes visible. Optimize images, fonts, and server response paths to improve it.<\/li>\n\n\n\n<li><strong>Interaction to Next Paint (INP):<\/strong> Measures input responsiveness across a page\u2019s lifecycle (replacing FID). Improve by reducing JavaScript work and keeping the main thread free.<\/li>\n\n\n\n<li><strong>Cumulative Layout Shift (CLS):<\/strong> Visual stability. Prevent late layout shifts caused by images, ads, and dynamic components.<\/li>\n\n\n\n<li><strong>Time to First Byte (TTFB):<\/strong> Server responsiveness. Optimize back-end performance, caching, and network distance.<\/li>\n\n\n\n<li><strong>First Contentful Paint (FCP):<\/strong> First pixels painted. Often improved along with LCP.<\/li>\n<\/ul>\n\n\n\n<p><strong>Heuristic targets to aim for:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>LCP: ~2.5s or less on typical mobile networks<\/li>\n\n\n\n<li>INP: ~200ms or less<\/li>\n\n\n\n<li>CLS: ~0.1 or less<\/li>\n\n\n\n<li>TTFB: ~0.8s or less on mobile<\/li>\n<\/ul>\n\n\n\n<p>You don\u2019t need perfection everywhere.
