Schema.org JSON-LD checks before publishing structured data
Generated schema can improve machine understanding, but every property should match visible page content and the selected schema type.
Match visible content
Keep names, dates, prices, ratings, questions, and descriptions aligned with what users can actually see on the page.
Choose the right type
Use Article, FAQ, Product, or LocalBusiness only when the page content genuinely fits that schema vocabulary.
Validate required fields
Run the JSON-LD through structured data testing tools and fix missing, invalid, or misleading properties before deployment.
Keep data current
Update generated schema when prices, availability, addresses, opening hours, authors, or FAQ answers change.
A practical example, an edge case, and a maintainer note
Edge case
Valid JSON-LD can still be ineligible for rich results when required properties are absent or markup contradicts visible content.
Maintainer note
I publish only facts users can verify on the page and maintain markup alongside the content that supplies those facts.
