Next.js SEO Guide

Production-grade SEO architecture for Next.js 15 App Router: metadata, structured data, sitemap, and Core Web Vitals.

Why SEO matters for Next.js

Next.js 15 with App Router enables server-first rendering, dynamic metadata, and optimal Core Web Vitals. This page demonstrates a fully SEO-optimized structure: semantic HTML, canonical URLs, Open Graph and Twitter cards, and JSON-LD structured data.

Metadata and crawlability

Every page uses generateMetadata or static metadata with a canonical URL, robots directives, and full Open Graph and Twitter metadata. Private pages use noindex.

Structured data

We inject Organization, WebSite, FAQPage, Article, and BreadcrumbList schemas via application/ld+json in the initial HTML so crawlers see them without executing JavaScript.

Performance and Core Web Vitals

We use Server Components by default, next/image with priority for above-the-fold assets, font optimization with next/font, and package import optimization to minimize client JS.
