How Next.js Processes Metadata
Next.js 13+ App Router processes metadata server-side before streaming HTML to the client. You can define static `metadata` objects in `layout.tsx` or `page.tsx`, or dynamically resolve async parameters via `generateMetadata({ params, searchParams })`. Next.js automatically injects standard `<head>` tags (Open Graph, Twitter Cards, canonical links, and viewport specifications) with zero client JavaScript overhead.
Next.js Setup Instructions
Define Base URL in Root Layout
Add `metadataBase: new URL('https://yourdomain.com')` inside your root `app/layout.tsx` so all social images resolve to absolute URLs.
Add Typed Metadata in Page Route
Export a static `metadata: Metadata` object or an async `generateMetadata` function inside your `app/[slug]/page.tsx` file.
Attach Social Card Image
Place a 1200x630 PNG/JPG in your route folder as `opengraph-image.png` or configure `openGraph.images` array.
Validate Output with OmniSEOTools
Test your live or localhost preview URL in this validator to ensure zero tag truncations and proper aspect ratios.
- Use `metadataBase: new URL('https://example.com')` in your root `app/layout.tsx` to automatically resolve relative image and canonical URLs.
- Leverage Next.js `opengraph-image.tsx` with `@vercel/og` to dynamically render custom 1200x630 branded graphics on the edge.
- Implement dynamic `generateMetadata({ params })` on nested dynamic routes to prevent duplicate title tags across product and article pages.
- Specify `twitter.card: 'summary_large_image'` to command maximum timeline visibility on X / Twitter feeds.
