Schema markup generator (JSON-LD)
Fill in the form and the tool generates Schema.org markup ready to paste into your page: Article, FAQ, local business or breadcrumbs. Empty fields are simply left out. Everything runs in your browser.
Paste it anywhere in the page, ideally in the head. Then validate it with Google's Rich Results Test.
What a schema markup generator does
Schema.org markup describes the content of a page in a format search engines understand without ambiguity. It is the entry ticket to rich results: expandable FAQs, breadcrumbs in the displayed URL, local business listings with opening hours. JSON-LD is the format Google recommends: a simple script block, independent of the visible HTML. This generator builds that block for you, with no code to write by hand.
The one rule never to break
Structured data must describe content that is actually visible on the page. Marking up an FAQ that is not on the page, or an invented review, exposes you to a manual action from Google. Only fill in what exists: the tool leaves out empty fields by itself.
After going live
Run the page through the Rich Results Test to check that the markup is read, then follow the Enhancements section of Search Console: that is where Google reports errors and the number of eligible pages.
