Zinn® SEO: Structured data

What it does

• Your knowledge graph — Who runs the site — organisation or person, name, logo, profiles elsewhere, contact points — as the publisher of the site and of every article.
• One graph per page — Every page prints one schema.org graph joined by @id: your blocks, WooCommerce products and Page Builder Sandwich blocks join it instead of printing more scripts, and with another SEO plugin they join that plugin's graph.
• Pages, articles and authors — Each page typed for what it is, articles with their dates, main image and section, breadcrumbs, languages with Tranzly, and authors as one person with their job, credentials and expertise.
• Offline structured-data check — Checks a page against schema.org and Google's current rich-result rules on your own site, in the editor and the admin, with nothing sent anywhere — including which results Google no longer shows.
• Site graph for AI agents — One address where AI agents read every page as schema.org data, and any page's full graph, listed in llms.txt.
• Other plugins join your graph — Structured data from WooCommerce and Page Builder Sandwich is printed inside the one graph, never as a second script.
• Rich-result rules built in — Google's rules for each rich result, with their current status, checked without leaving the site.
• Schema types per page (Pro) — Add a recipe, event, job, course, software, book, film, review, service, video, FAQ or Q&A to any page from a simple form.
• Visual schema builder (Pro) — Design any schema.org type from the whole vocabulary, filled from each post's title, image, dates, custom fields or terms — or copy one from any page's structured data.
• Schema by rule (Pro) — Give a type to every post of a content type, in a category or with a custom field, with no editing.
• About, mentions and speakable (Pro) — Say what a page is about and what it mentions (with Wikipedia or Wikidata), which parts voice assistants read, and its most important links.
