Build common JSON-LD types without inventing schema names
Structured data helps machines understand pages, but invalid JSON or made-up types waste the effort. Editors want FAQ and Product blocks quickly; SEOs want valid JSON-LD; nobody should confuse “parses as JSON” with “will show a rich result.”
Why this is worth doing in the browser
DevNestro’s Schema Markup Generator supports Article, FAQPage, Product, Organization, LocalBusiness, BreadcrumbList, Person, WebSite, and Event. Fields map into schema.org objects under @context https://schema.org, then the JSON is validated before you copy the raw JSON-LD or a script tag wrapper. The tool never claims Google rich-result eligibility, Search Console approval, or ranking impact.
How to use the tool
Pick a type, fill the fields (FAQ pairs separated by blank lines; breadcrumbs as Name|URL), generate, fix any JSON validation error, and paste into your page. Use Meta Tag Generator for classic meta tags and SEO Preview when you also care about Open Graph cards.
- Valid JSON-LD is not a rich-result guarantee.
- Keep types limited to the supported list in V1.
- Review Product offers and Event dates carefully before publishing.
- Do not invent undocumented schema properties in production templates.
