The Essential Technical SEO Checklist for 2026
A practical guide to site speed, crawlability, structured data, and core web vitals that actually move rankings.
Technical SEO is the infrastructure layer that lets your content compete. Slow, broken, or poorly structured sites cap rankings regardless of how strong your copy is.
Core Web Vitals
Optimize LCP, INP, and CLS with image compression, lazy loading, and minimal render-blocking scripts. Test on real devices, not lab scores alone.
Crawl & Index Health
Fix redirect chains, orphan pages, and duplicate content. Use structured data where it adds clarity — articles, FAQs, and local business markup when relevant.
