Technical SEO improvement starts with a crawl audit using Screaming Frog or Sitebulb to identify broken links, redirect chains, and orphaned pages. Fix 404s, consolidate 301 redirect chains to single hops, and ensure every important page is reachable within three clicks from your homepage. Your XML sitemap should exclude noindexed pages, pagination, and parameter URLs that waste crawl budget. Page speed directly impacts rankings and conversions. Aim for a Largest Contentful Paint under 2.5 seconds and a Cumulative Layout Shift below 0.1. Compress images to WebP, enable browser caching, minify CSS and JavaScript, and consider a CDN if you serve traffic beyond your hosting region. For Canadian sites targeting multiple provinces, a North American CDN with Toronto and Montreal edge nodes makes sense. We've seen 15-30% bounce rate reductions from shaving two seconds off load time. Mobile responsiveness isn't optional since Google's mobile-first indexing. Test your site on actual devices, not just Chrome DevTools. Check tap target spacing, font sizes, and horizontal scroll issues. Implement structured data for your business type, whether that's LocalBusiness, Organization, Product, or Article schema. Google's Rich Results Test shows what snippets you're eligible for. Security and HTTPS are table stakes now. Mixed content warnings kill trust and rankings. If you're on shared hosting, confirm your server supports HTTP/2 and modern TLS versions. Disable outdated protocols like TLS 1.0. Core Web Vitals matter more for commercial queries than informational ones. If you run an e-commerce site, prioritize Interaction to Next Paint by reducing third-party scripts, especially analytics and chat widgets that block the main thread. We routinely strip out five or six tracking pixels that clients don't even use anymore and see immediate INP improvements of 100-200ms. Fix the biggest problems first rather than chasing a perfect Lighthouse score across 500 pages simultaneously.
