Free Schema Markup Generator

What is schema markup (and why AI needs it)?

Schema markup is structured data — almost always written as JSON-LD — that describes your page in a format machines read directly. Instead of guessing what your content means, search engines and AI assistants get it spelled out: this is a question and its answer, this is a product with this price and rating, this is an article by this author. Clean structured data makes a page easier to parse, quote and cite. For the full background, see our structured data explainer and citability guide.

Schema types this generator supports

FAQPage

Wraps your questions and answers so engines can lift them straight into results and AI answers — one of the most citable formats, because the Q&A shape maps directly to how people ask AI. Add it to any page that shows those Q&As.

Article

Describes a blog post or guide — headline, author, publish and modified dates — which helps establish authorship and freshness for news, blog and guide pages.

Product & Review

Product markup carries name, brand, price and aggregate rating so a product page can qualify for rich product results. Review markup describes a single review with its rating and author. Only mark up ratings that are genuinely shown on the page.

Organization

Tells engines who you are — name, logo, website and official social profiles (sameAs). It's the backbone of your brand's knowledge graph entry, and worth adding once to your homepage.

HowTo & Breadcrumb

HowTo breaks a task into ordered steps; Breadcrumb exposes your page's position in the site hierarchy, which both search and AI use to understand structure.

How to add JSON-LD to your page

Pick a type above, fill in the fields, and hit Generate.
Copy the whole <script type="application/ld+json"> block.
Paste it into the <head> of the page it describes (the body works too).
Validate with Google's Rich Results Test or the Schema.org validator before you ship.

Common schema mistakes to avoid

Marking up content that isn't on the page. Schema must match what a visitor actually sees, or it can be ignored or flagged.
Invalid JSON. A stray comma or missing quote breaks the whole block — always validate.
Wrong or fake ratings. Only add aggregateRating or Review when real reviews are shown.
Duplicating types. One canonical block per entity per page — don't ship three FAQPage blocks.

Frequently asked questions

Is this schema markup generator free?

Yes — completely free, no signup and no limits. Pick a schema type, fill in the fields, and it builds valid JSON-LD in your browser. Nothing is sent to a server; you just copy or download the code.

What schema types can I generate?

FAQPage, Article, Product, Review, Organization, HowTo and Breadcrumb. Each produces JSON-LD in the exact shape Google and AI engines expect, so you can mark up the page that matches.

What is schema markup?

Schema markup is structured data — usually written as JSON-LD — that describes your page's content in a format machines read directly, so search engines and AI assistants know exactly what each part means instead of guessing. See our structured data explainer for the full picture.

What is FAQ schema (FAQPage)?

FAQPage schema is JSON-LD that wraps your questions and answers so engines can lift them straight into search results and AI answers. It's one of the most citable formats because the Q&A structure maps perfectly to how people ask AI questions.

Does schema markup help with AI visibility?

It helps engines parse and quote you accurately. Structured data isn't a guaranteed ranking boost, but it removes ambiguity about what your content means, which makes your pages easier for AI to understand and cite correctly.

Is JSON-LD better than microdata?

For almost every case, yes. Google recommends JSON-LD because it lives in one <script> block in the <head> instead of being woven through your HTML, so it's far easier to add, read and maintain. This tool outputs JSON-LD.

Where do I put the JSON-LD code?

Paste the <script type="application/ld+json"> block into the <head> (or anywhere in the body) of the page it describes — the FAQ block on the page showing those Q&As, the Product block on that product page. Only mark up content that's actually visible on the page.

How do I check my schema is valid?

Paste your page or the code into Google's Rich Results Test or the Schema.org validator. They flag missing required fields and type errors before Google ever crawls it.
