The technical SEO foundation every site needs in 2026

The matmad team·

Great content won't rank on a broken foundation. These are the technical essentials we ship with every build in 2026.

Core Web Vitals

  • LCP under 2.5s — fast largest content paint
  • INP under 200ms — responsive to interactions
  • CLS under 0.1 — no layout shift

Crawlability & indexing

  • Clean, descriptive URLs
  • XML sitemap + robots.txt, submitted to Search Console
  • Canonical tags to avoid duplicate content
  • Correct status codes and 301 redirects

Structured data

JSON-LD schema (Organization, LocalBusiness, Service, FAQ, Article) helps you win rich results and get cited by AI search engines like ChatGPT, Perplexity and Google AI Overviews.

The rest of the basics

  • HTTPS everywhere + security headers
  • Mobile-first responsive design
  • Unique titles & meta descriptions per page
  • Optimised images (WebP/AVIF, lazy loading)
