Largest Contentful Paint (LCP) measures how quickly the main content appears. Interaction to Next Paint (INP) measures how quickly the page responds when someone taps or clicks; it replaced an older metric, First Input Delay, in 2024. Cumulative Layout Shift (CLS) measures how much the page jumps around while loading.<\/p><h2>Why It Matters for Your Business<\/h2><p>These scores reflect frustrations every visitor knows: a slow hero image, a button that lags or a page that shifts just as you tap, so you hit the wrong link. Google uses them as part of its ranking signals, though great content still matters more. For a contractor whose customers search on phones, a fast, stable page keeps more of them from leaving.<\/p><h2>Good to Know<\/h2><p>Tip: check your scores in Google Search Console or PageSpeed Insights, which use data from real Chrome users when enough is available. Common fixes include compressing large images, setting image dimensions, reducing heavy plugins and scripts, using caching and choosing quality hosting. Focus on the pages that bring in the most visitors first.<\/p><div class=\"sfl-box\"><h4>Related terms<\/h4><div class=\"sfl-rel\"><a href=\"\/fr\/learn\/glossary\/page-speed\/\">Page speed<\/a><a href=\"\/fr\/learn\/glossary\/load-time\/\">Load time<\/a><a href=\"\/fr\/learn\/glossary\/google-search-console\/\">Google Search Console<\/a><a href=\"\/fr\/learn\/glossary\/technical-seo\/\">Technical SEO<\/a><a href=\"\/fr\/learn\/glossary\/cdn\/\">CDN<\/a><\/div><\/div><nav class=\"sfl-pn\"><a href=\"\/fr\/learn\/glossary\/copywriting\/\"><small>\u2190 Previous<\/small><b>Copywriting<\/b><\/a><a href=\"\/fr\/learn\/glossary\/country-code-tld\/\" class=\"r\"><small>Next \u2192<\/small><b>Country-code TLD<\/b><\/a><\/nav><\/article><aside class=\"sfl-aside\"><div class=\"sfl-box sfl-box-o\"><h4>Want to be found on Google?<\/h4><p>On-page SEO, Google Business Profile and analytics are built into our website packages.<\/p><a class=\"sfl-btn sfl-btn-w\" href=\"\/fr\/web-design-development\/#pricing\">See website packages<\/a><\/div><div class=\"sfl-box\"><h4>Step-by-step guides<\/h4><div class=\"sfl-rel sfl-col\"><a href=\"\/fr\/learn\/guides\/speed-up-a-slow-wordpress-site\/\">How to Speed Up a Slow WordPress Website<\/a><\/div><\/div><div class=\"sfl-box\"><h4>More in SEO &amp; Local Search<\/h4><div class=\"sfl-chips\"><a href=\"\/fr\/learn\/glossary\/search-engine-optimization\/\">Search engine optimization<\/a><a href=\"\/fr\/learn\/glossary\/keyword\/\">Keyword<\/a><a href=\"\/fr\/learn\/glossary\/keyword-research\/\">Keyword research<\/a><a href=\"\/fr\/learn\/glossary\/search-intent\/\">Search intent<\/a><a href=\"\/fr\/learn\/glossary\/on-page-seo\/\">On-page SEO<\/a><a href=\"\/fr\/learn\/glossary\/off-page-seo\/\">Off-page SEO<\/a><a href=\"\/fr\/learn\/glossary\/technical-seo\/\">Technical SEO<\/a><a href=\"\/fr\/learn\/glossary\/title-tag\/\">Title tag<\/a><\/div><\/div><\/aside><\/div><script type=\"application\/ld+json\">{\"@context\":\"https:\/\/schema.org\",\"@type\":\"DefinedTerm\",\"name\":\"Core Web Vitals\",\"description\":\"Core Web Vitals are Google's three measures of real-world page experience: loading speed (LCP), responsiveness (INP) and visual stability (CLS).\",\"url\":\"https:\/\/sitefitters.com\/learn\/glossary\/core-web-vitals\/\",\"inDefinedTermSet\":{\"@type\":\"DefinedTermSet\",\"name\":\"Business Website 101 Glossary\",\"url\":\"https:\/\/sitefitters.com\/learn\/glossary\/\"}}<\/script>","protected":false},"excerpt":{"rendered":"<p>Learn \/ Glossary \/ SEO &amp; Local Search Core Web Vitals Explained.
