Definition (site FAQ): structured data is machine-readable markup (such as Schema or JSON-LD) that declares what something is, its price, availability, etc. It makes explicit facts easier to recognise; whether and how AI or search uses it still needs observation.
Recommended types (by page)
| Page type | JSON-LD suggestion |
|---|---|
| Site-wide | Organization (name, url, email) |
| Product / facts | SoftwareApplication or Product |
| FAQ | FAQPage |
| Guide | HowTo (verifiable steps, no fake performance promises) |
| Comparison category | ItemList + Article |
| Glossary term | DefinedTerm |
| Case | Article + link to metrics disclaimer |
| Every page | BreadcrumbList; unique canonical |
Organization minimum fields (Winin example semantics)
- name: Winin
- url: https://winin.ai
- email: contact@winin.ai
Implementation steps
- Choose the canonical URL; avoid multiple URLs for one product with differing JSON-LD.
- Keep fields consistent with visible copy (especially price and availability).
- Validate syntax with rich-result tools (does not guarantee AI citation).
- Add to sitemap; keep robots open for crawlers you want to reach.
- Watch with Edith-class monitoring whether answers improve — Schema ≠ automatic shortlist.
What Schema is not
- Not black-hat keyword stuffing.
- Not a guarantee of recommendation share.
- Do not mark up unapproved or false certifications.
With fact pages and the loop
Approve in Homer first → write fact pages and JSON-LD → Friday advances tasks → Edith retests. See fact-pages · geo loop.
FAQ
Q: Is JSON-LD enough without content work? A: No. GEO still depends on verifiable statements, comparison reasons and retesting.
Q: What to watch with FAQPage? A: Q&A must match visible content; avoid hidden keywords.
Common consistency errors
- JSON-LD price differs from the visible price.
- Product and FAQ specs contradict each other.
- Organization email or URL is wrong, conflicting with the contact fact page.
- One SKU across several URLs declares different availability.
Minimum launch pack
- Site-wide Organization
- Product/SoftwareApplication for core products
- FAQPage for key FAQs
- Article + BreadcrumbList for fact pages
- Sitemap inclusion and a crawl spot-check
