It is the closest single number to \u201chow fast did the page feel\u201d. Slow LCP usually comes from large unoptimised images, slow servers or render-blocking resources.<\/p>\n<p class=\"p1\"><b>How to improve it:<\/b><b><\/b><\/p>\n<ul class=\"ul1\">\n<li class=\"li3\">Compress and correctly size hero images, and serve modern formats like WebP.<\/li>\n<li class=\"li3\">Use a CDN and good hosting to cut server response time.<\/li>\n<li class=\"li5\">Preload the main image or font and defer non-critical scripts.<\/li>\n<\/ul>\n<h3 class=\"p4\"><span class=\"ez-toc-section\" id=\"Interaction_to_Next_Paint_INP\"><\/span>Interaction to Next Paint (INP)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\">INP measures how quickly the page responds when a user taps, clicks or types. It replaced First Input Delay in March 2024 and is now the most commonly failed Core Web Vital, with around 43% of sites missing the 200ms target in 2026. Heavy JavaScript is the usual culprit.<\/p>\n<p class=\"p1\"><b>How to improve it:<\/b><b><\/b><\/p>\n<ul class=\"ul1\">\n<li class=\"li3\">Break up long JavaScript tasks so the main thread stays free.<\/li>\n<li class=\"li3\">Remove or defer unused scripts and third-party tags.<\/li>\n<li class=\"li5\">Keep event handlers light and avoid blocking the page during interaction.<\/li>\n<\/ul>\n<h3 class=\"p4\"><span class=\"ez-toc-section\" id=\"Cumulative_Layout_Shift_CLS\"><\/span>Cumulative Layout Shift (CLS)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\">CLS measures unexpected movement, the annoying jump when an image or ad loads and pushes the button you were about to tap.
