Schema markup is structured data written in the schema.org vocabulary and embedded as JSON-LD — a <script type="application/ld+json"> block that restates a page's meaning in machine-readable form, such as a Product's price or an Article's author. Build valid JSON-LD structured data for FAQ, Article, Breadcrumb, LocalBusiness and Product — the script tag updates live as you type, with copy and download. Everything runs in your browser.
Choose a schema type — FAQ, Article, Breadcrumb, LocalBusiness or Product — and fill in the fields for your page. The generator assembles a valid JSON-LD block and updates the code as you type. Copy the finished <script type="application/ld+json"> tag and paste it into your page's <head> or anywhere in the body; the position does not matter to search engines.
Only fields you fill in are included, so empty values are left out of the output. Before publishing, validate the result with Google's Rich Results Test or the Schema Markup Validator to confirm it is error-free. Working on the rest of your tags? Try the meta tag generator and the Open Graph preview, build a longer Q&A block with the FAQ schema generator, and check the snippet those tags produce in the SERP snippet preview.
