When multiple sites have similar content quality and backlink profiles, Google often leans on user experience metrics to choose a winner.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This means that even a small improvement in loading speed or layout stability can tip the scale in your favor.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Core_Web_Vitals_vs_Traditional_SEO_Signals\"><\/span><strong>Core Web Vitals vs. Traditional SEO Signals<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional SEO tactics like keyword targeting and backlinks still matter. However, metrics like <strong>site speed, interaction delay<\/strong>, and <strong>visual stability<\/strong> are now deeply intertwined with SEO performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This doesn\u2019t mean local SEO is dead\u2014far from it. But if you\u2019re still asking <a class=\"\" href=\"https:\/\/duckyunlimited.com\/blog\/is-local-seo-dead\">is local SEO dead<\/a>, the answer is no.
