Site speed is a confirmed ranking factor, particularly since Google rolled Core Web Vitals into its algorithm in 2021. Pages that load in under 2.5 seconds for Largest Contentful Paint (LCP) and respond to interactions within 100ms (First Input Delay) rank better than slower competitors, all else equal. Google Search Console now surfaces these metrics directly, so the search engine is telling you it matters. The impact shows up in two ways. First is the direct ranking boost—Google's own studies found that as page load time goes from one second to five seconds, bounce probability jumps 90%. High bounce rates signal poor user experience, which feeds back into rankings. Second is crawl budget: if your site is slow, Googlebot crawls fewer pages per session, meaning new content and updates get indexed slower. For large sites in our portfolio running 500+ pages, we've seen indexation delays of weeks when server response times drift above 600ms. Core Web Vitals matter most on mobile. Google's mobile-first index means your mobile speed is your primary speed. A desktop site loading in 1.2 seconds but a mobile version at 4.8 seconds will hurt you. We routinely see 15–25 position drops when LCP exceeds 4 seconds on mobile, especially in competitive niches like local services or e-commerce. At Ottawa SEO, we treat anything above 3 seconds total load time as a red flag. Real-world fixes that move the needle include image compression (WebP format, lazy loading), reducing JavaScript bloat, enabling browser caching, and switching to faster hosting. A typical WordPress site on shared hosting in Toronto might run 4–6 second load times; moving to a managed host with CDN often cuts that to 1.5–2 seconds. That difference alone can recover 10–20 organic positions in moderately competitive SERPs. Speed won't rescue terrible content, but between two equally relevant pages, the faster one wins. Track your Core Web Vitals monthly and treat any regression as urgent.
