SEO explanation and Next.js listing tutorial

Added

  • What SEO does for a public website explains SEO as a discoverability and usefulness system rather than a ranking trick.

  • The explanation connects server-rendered content, metadata, internal links, sitemap and robots rules, structured data, performance, and Search Console.

  • It records that ordinary Google sitelinks are automated and cannot be manually configured, and that the separate sitelinks search box was retired beginning November 21, 2024.

  • Build a search-ready Next.js listing site walks through canonical records, Server Components, generateStaticParams, generateMetadata, JSON-LD, sitemap.ts, robots.ts, raw-response checks, and Search Console.

Navigation and illustration

  • Both pages are linked from the component navigation and their Diátaxis landing pages.

  • seo-discovery-system.mmd preserves the editable Mermaid source for the shared orientation figure.

  • The diagram build emits a fixed original, host-controlled SVG, standalone adaptive SVG, and Themed SVG manifest.

Verification intent

The examples favor canonical, indexable, meaningful HTML and explicitly reject keyword stuffing, doorway pages, false structured data, and guaranteed-ranking claims. Production checks inspect the raw response rather than relying on a hydrated browser DOM.
