SEO in 2026 is more technical than ever. Here's what actually matters.

Core Web Vitals

Google's ranking signals focus heavily on user experience:

LCP (Largest Contentful Paint) — aim for under 2.5s
INP (Interaction to Next Paint) — under 200ms
CLS (Cumulative Layout Shift) — under 0.1

Structured Data

JSON-LD structured data helps search engines understand your content.

Canonical URLs

Always set canonical URLs to avoid duplicate content penalties.

Conclusion

Technical SEO + great content = sustainable organic growth.
