About JSON-LD & Meta Tag Generator

JSON-LD & Meta Tag Generator builds the structured-data script and social meta tags for a page from a small form.

It covers the common schema.org types and produces Open Graph and Twitter card tags from the same fields. It runs in your browser.

How to use it

  1. Pick a type such as Article or Product.
  2. Fill in the fields you have. Empty ones are left out.
  3. Copy the JSON-LD script and the meta tags into your page's head.

Common questions

Which types are supported?

Article, Product, Organization, WebSite, FAQPage, and BreadcrumbList.

Do I need both the JSON-LD and the meta tags?

They serve different consumers. JSON-LD feeds search engines' structured data, while Open Graph and Twitter tags control link previews on social platforms.

Is the output validated?

It is well-formed JSON-LD for the fields given, but run it through a structured-data testing tool before relying on it.

Does anything leave my browser?

No. The tool runs entirely on this page.
