SEO & metadata

Guidance for SEO, structured data, and metadata on the site.

Metadata config

• Root export: lib/config/metadata.ts — default title template (%s | {name}), description, keywords, author, openGraph, twitter, robots, etc. Uses lib/config/personal and lib/config/index.ts (e.g. config.baseUrl).
• Usage: Root layout and pages import and extend this metadata; blog and other routes use generateMetadata for dynamic titles/descriptions/OG.
• Cache profiles: lib/cache.ts — exports CACHE_PROFILES (DEFAULT = 300s, ARTICLES = 900s, DYNAMIC = 60s) and CACHE_TAGS (per integration). Use getCacheConfig(profile, tags) in fetch calls to align page freshness. Use CACHE_TAGS.ARTICLE(slug) for per-article cache invalidation.

JSON-LD (structured data)

• Schema builders: lib/seo/json-ld.ts — functions return WithContext<Thing> for:
  • getPersonSchema(), getOrganizationSchema(), getWebSiteSchema() — used in root layout.
  • getProfilePageSchema() — profile/home page.
  • getBlogPostingSchema(frontmatter) — article pages.
  • getBreadcrumbSchema(items) — breadcrumb list.
  • getMusicPlaylistSchema(...), getFAQPageSchema(...), getSoftwareSourceCodeSchema(...) — when needed.
• Rendering: components/seo/json-ld-script.tsx — <JsonLdScript data={schema} /> outputs a <script type="application/ld+json">. Use this instead of inlining JSON-LD.
• Breadcrumbs: components/seo/breadcrumb-schema.tsx — <BreadcrumbSchema items={[{ name, href }]} />; prepends "Home" if not first. Renders JSON-LD via JsonLdScript.
• Exports: components/seo/index.tsx — re-exports BreadcrumbSchema, JsonLdScript.

Sitemap and robots

• Sitemap: app/sitemap.ts — default export returns MetadataRoute.Sitemap. Includes /, /blog, /blog/[slug] (from articles/), /open-source, /spotify. Uses config.baseUrl; trailing slashes follow project config.
• Robots: app/robots.ts — allow/disallow rules; references sitemap URL. Align with lib/config/metadata.ts robot settings if needed.

Open Graph and images

• Default OG image: app/opengraph-image.tsx — dynamic OG image (ImageResponse); uses personal avatar and metadata. Exports alt, size, contentType, metadata.
• Blog OG: app/blog/[slug]/opengraph-image.tsx — per-article OG image when present.
• Share helpers: lib/seo/share-metadata.ts — utilities for share URLs and metadata if used elsewhere.

Trailing slashes and URLs

• The site uses trailing slashes. Build canonical and sitemap URLs with config.baseUrl and consistent path format (e.g. /blog/, /blog/slug/).

Analytics (GTM)

• Provider: components/providers/analytics-tracker.tsx — loads GTM when NEXT_PUBLIC_GTM_ID is set. Root layout includes it; analytics are non-blocking (defer third-party per best practices).
• Events: lib/analytics/events.ts and helpers in lib/analytics/ — use for tracking events if needed.

Adding a new page or schema

1. Page metadata: Export metadata or generateMetadata from the page; use title template and description from lib/config/metadata.ts where appropriate.
2. JSON-LD: Add or reuse a getter in lib/seo/json-ld.ts; render with <JsonLdScript data={...} /> in the page or layout.
3. Breadcrumbs: Add <BreadcrumbSchema items={[...]} /> with the page’s breadcrumb trail.
4. Sitemap: Add the URL to app/sitemap.ts with the desired priority and changeFrequency.
