Build valid JSON-LD structured data for 9 schema types — Article, FAQ, Product, Local Business and more. Fill in a plain-language form, watch the code build live, then copy or download it. Runs entirely in your browser.
Structured data is the quiet workhorse of modern SEO — it does not change what your page says to readers, it changes what your page says to search engines. Add schema markup and you hand Google a labelled map of your content, which can earn rich results like star ratings, FAQ dropdowns and breadcrumbs. The catch is that schema is written in JSON-LD, and one stray comma breaks the whole block. This generator removes that risk: pick a type, fill a form written in plain language, and get valid JSON-LD every time. Nothing you enter is uploaded, logged or stored.

Pick from Article, FAQ, Product, Local Business and six more. The form re-renders for the type you select.
Required fields are marked. The JSON-LD preview updates live as you type — no generate button to hunt for.
Copy the ready-to-paste script block, or download the raw JSON. Add it to your page head and confirm with Google's Rich Results Test.
No stray commas or broken brackets. The output is assembled programmatically, so the JSON is well-formed every time.
Watch the structured data build as you type, so you can see exactly what you are shipping before you copy it.
Each type asks for the required and recommended properties, so you are not guessing which fields matter.
All processing happens in your browser. Nothing you enter is uploaded to any server or stored anywhere.
Company name, logo, URL, contact and social profiles — the backbone of brand knowledge-panel signals.
Extends Organization with address, opening hours, phone and geo-coordinates for local-pack visibility.
Headline, author, publish and modified dates and image — powers article rich results.
Question and answer pairs that can surface as expandable dropdowns under your listing.
Ordered steps for tutorials and instructional content that Google can render as a guide.
Name, description, price, availability and aggregate rating for shopping-style rich results.
Name, start and end dates, location and offers for event cards in search.
Name, job title, image and social profiles — useful for author and profile pages.
Site name, URL and an optional Sitelinks Search Box for your homepage.
Add Article markup to posts so they qualify for enhanced article results and Top Stories eligibility.
Mark up a homepage with address and hours to strengthen your place in the local pack and on maps.
Turn a product or help FAQ into FAQ structured data that can expand right in the search result.
Give a step-by-step guide HowTo markup so search engines understand and can surface the steps.
Add price, availability and ratings to e-commerce pages for shopping-style rich results.
Prototype valid JSON-LD fast before wiring it into a template, without reading the schema.org docs end to end.
Structured data for content users cannot see breaks Google's guidelines and can trigger a manual action.
Then add recommended ones — more accurate, complete fields generally mean better rich-result eligibility.
If a price or date changes on the page, update the schema too so the two never disagree.
Nest related types where it makes sense rather than stacking unrelated blocks that compete for meaning.
Run the output through Google's Rich Results Test and the Schema Markup Validator to confirm the values.
Aggregate ratings must reflect genuine, on-page reviews. Fabricated ratings risk a structured-data penalty.
Schema markup is structured data — a standardised vocabulary from schema.org — that labels the meaning of your content for search engines, helping them understand and sometimes visually enhance your page in results.
JSON-LD is the JSON-based format for structured data. Google recommends it because it lives in a single script block, separate from your visible HTML, so it is the cleanest and least error-prone way to add schema.
Not directly — it is not a ranking factor on its own. What it can do is make you eligible for rich results, which often improve click-through rate and visibility in search.
Inside your page's HTML — ideally in the head, though JSON-LD also works in the body. In WordPress you can use a code block, an SEO plugin's schema field, or your theme's header.
No. Everything runs in your browser. Nothing you type is sent to a server, logged or stored.
Nine of the most-used: Organization, Local Business, Article, FAQ, HowTo, Product, Event, Person and Website.
The tool builds syntactically valid JSON-LD and flags missing required fields as you go. For a final check, run the output through Google's Rich Results Test.
Yes — you can place multiple JSON-LD blocks on one page. Keep one primary type per page and make sure every block describes content that is really there.
No. You fill in a plain-language form and the tool writes the code for you. Copy it, paste it, done.
Yes — unlimited use, no account, no watermark, and no limit on how many blocks you generate.
