Concept

JSON-LD is structured metadata for search intent

Define page entities with schema types so search engines can understand what each URL actually represents.

Use this tool to add machine-readable metadata that complements visible content. Choose a schema type based on page intent instead of relying only on text for crawling interpretation.

Typical choices include Article for editorials, Product for item pages, FAQPage for Q&A sections, and BreadcrumbList for hierarchical navigation context.

Schema selection by intent

Match the schema type to the page goal: Article for content, Product for commerce pages, FAQ for question blocks, and Breadcrumb for page hierarchy.

When to use

Use separate structured data types for blog posts, catalog pages, FAQs, and navigation-heavy pages so each URL has clear semantic meaning.

Validation checkpoints

Rich results are not guaranteed. Validate output with Google Search Console URL inspection and the Rich Results Test before publishing.

Results depend on crawl status and overall page quality; JSON-LD helps eligibility but does not guarantee ranking or display.

Frequently asked questions

Which schema types can I generate?

You can choose Organization, WebSite, Article, Product, Person, BreadcrumbList, or FAQPage and fill in the type-specific form to generate a JSON-LD script tag.

Can I copy the result or save it as a file?

Yes. You can copy the generated application/ld+json markup to the clipboard.

Can I publish the generated JSON-LD as is?

Empty values are removed, but you should confirm the markup matches the actual page content. Validate it with a structured data testing tool before publishing.
