{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"feat(seo): add BlogPosting structured data and article social metadata","articleBody":"## Context\n\nPublished TanStack blog posts expose titles, descriptions, authors, publication dates, and images in visible SSR content, but they currently emit no Article or BlogPosting JSON-LD. The shared SEO helper also gives every page og:type=website, including blog posts.\n\nGoogle documentation: https://developers.google.com/search/docs/appearance/structured-data/article\n\nRelevant route: src/routes/blog.$.tsx\n\n## Proposed scope\n\n- Emit BlogPosting JSON-LD on every published internal blog post.\n- Include accurate values for:\n  - headline\n  - description\n  - image\n  - datePublished\n  - dateModified when known\n  - author as Person or Organization\n  - publisher referencing the canonical TanStack Organization node\n  - mainEntityOfPage\n- Add optional updated/dateModified frontmatter support so revised posts can distinguish publication and modification dates.\n- Change blog post social metadata to og:type=article.\n- Add article:published_time and article:modified_time when applicable.\n- Reuse the canonical social image transformation already used by the route.\n\n## Acceptance criteria\n\n- BlogPosting JSON-LD is included in the raw SSR response for published internal posts.\n- Draft, future-dated, missing, and error pages do not emit indexable BlogPosting markup.\n- Author names use the same normalization as visible bylines.\n- Author URLs are included only when they identify a real maintainer profile or another stable public identity.\n- Publisher uses the same Organization @id and identity fields as the homepage graph.\n- dateModified is accurate; when no modification date is known, it is omitted or intentionally equals datePublished rather than invented.\n- Image URLs are absolute, crawlable, and representative of the article.\n- og:type is article on post pages and remains website on non-article routes.\n- Automated tests cover single author, multiple authors, missing header image, drafts, and modification dates.\n- Representative posts pass Google Rich Results Test validation.","author":{"url":"https://github.com/KevinVandy","@type":"Person","name":"KevinVandy"},"datePublished":"2026-08-14T12:54:32Z","url":"https://github.com/TanStack/tanstack.com/issues/1149"}
