What is JSON-LD structured data?

JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding structured data recommended by Google. It is placed inside a tag in your HTML and tells search engines key facts about your page content, enabling rich result features in search.

Where should I place the JSON-LD script tag?

Google recommends placing the block inside the section of your page, though it also works in the . For WordPress sites, use a plugin like Yoast SEO or add the tag via your theme's header.php.

Which schema type should I use for my page?

Use Article for blog posts and news pages, Product for e-commerce product pages, FAQ for pages with question-and-answer content, LocalBusiness for brick-and-mortar businesses, and BreadcrumbList to represent your site's navigation hierarchy.

Does adding JSON-LD guarantee rich snippets in Google?

No. Google uses structured data as a strong signal but may still choose not to display rich results. Your page must also meet Google's content quality guidelines and be indexed. Validate your markup with Google's Rich Results Test to maximize eligibility.

Is it safe to use multiple schema types on one page?

Yes. You can include multiple blocks on a single page — for example, both an Article and a BreadcrumbList schema. This tool generates one schema at a time; repeat the process for each type you need.

What happens if I leave optional fields blank?

Optional fields with blank values are automatically omitted from the generated JSON-LD. This keeps your output clean. Required fields must be filled in; the tool highlights them if you try to copy with required fields missing.
