Generate valid JSON-LD structured data — Article, FAQ, HowTo, Product, LocalBusiness, Organization — free.
Build valid JSON-LD structured data for the schema types search engines use most — Article, FAQ Page, HowTo, Product, Local Business, and Organization — without needing to hand-write the JSON or memorize schema.org's exact field names.
Structured data doesn't change what your page looks like to a visitor; it's a machine-readable description of the same content, placed in a script tag search engines read but people don't see. It's what enables things like star ratings, FAQ dropdowns, or step-by-step instructions to appear directly in search results, and it's a factual description — the schema has to genuinely match what's visibly on the page, not describe content that isn't actually there.
Paste the generated script tag into your page's HTML, ideally in the head, and it takes effect the next time the page is crawled — there's no separate submission step, since crawlers pick up structured data as part of a normal crawl of the page.
Nothing here touches a server — everything you enter and the JSON-LD it generates stay entirely in your browser.
No — valid schema makes a page eligible for rich results (like FAQ dropdowns or star ratings), but Google decides case by case whether to actually show them. It’s a necessary condition, not a guarantee.
You technically can, but you shouldn’t — schema is meant to describe content that’s genuinely visible on the page. Search engines have taken action against sites that add structured data for content that doesn’t actually appear there.
Paste the entire script tag into your page’s HTML, most commonly in the <head> section — it takes effect the next time a search engine crawls that page.
Google’s Rich Results Test and the Schema.org validator are the standard tools for checking a piece of JSON-LD is both valid and eligible for rich results — worth running the generated code through one of these before publishing.
