(CrUX \/ Field Data)?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>According to Chrome UX Report releases, <strong>only about 43\u201344% of origins (sites) currently pass the Core Web Vitals assessment<\/strong>, using real-world aggregated (CrUX) data (<a href=\"https:\/\/developer.chrome.com\/docs\/crux\/release-notes?utm_source=chatgpt.com\">Chrome for Developers<\/a>).<\/li>\n\n\n\n<li>Google also notes that <strong>over 40% of sites pass all CWV metrics<\/strong>\u2014consistent with the 43\u201344% figure (<a

even fewer on mobile (<a href=\"https:\/\/jetpage.co\/blog\/lighthouse-pagespeed-insights-accuracy?utm_source=chatgpt.com\">jetpage.co<\/a>).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Another estimate suggests <strong>55% of websites fail the CWV assessment<\/strong> as of August 2023 (<a

It\u2019s normal for most sites <strong>not<\/strong> to pass CWV\u2014passing is still relatively rare (around 30\u201345%).<\/p>\n\n\n\n<hr class=\"wp-block-separator
