Overview

Next.js App Router gives you SEO primitives for free. The 80/20 is meta tags, sitemap, robots, and structured data. Get those right and you're already ahead of most of the web.

What you need

• Metadata API on every page (title, description, OG, Twitter). • app/sitemap.ts generated programmatically. • app/robots.ts allowing AI crawlers explicitly. • JSON-LD on pages where it adds meaning.

What you don't need yet

• Server-side rendering tricks beyond defaults. • Multiple sitemaps for sub-sections. • Aggressive caching headers.
