Full SEO stack checklist for 2026
Metadata, indexing, schema, speed and content — a practical layer-by-layer checklist for Next.js sites.
8 min
A polished site without an SEO skeleton rarely ranks. In 2026 the baseline is infrastructure: canonical, hreflang, sitemap, robots, schema, Core Web Vitals and index monitoring in Google and Yandex.
Three layers
- Metadata: unique titles, descriptions, canonical, hreflang, OG 1200×630
- Discovery: sitemap with alternates, robots.txt, IndexNow, RSS full-text
- Quality: JSON-LD, CWV targets, llms.txt, internal linking and breadcrumbs
At xm8 we ship this stack in the first website version — not as an add-on, but as the minimum for B2B projects where search traffic pays back development.
