About this tool

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.

Best practices

Only mark up visible content

Structured data for content users cannot see breaks Google's guidelines and can trigger a manual action.

Fill required fields first

Then add recommended ones — more accurate, complete fields generally mean better rich-result eligibility.

Keep markup in sync

If a price or date changes on the page, update the schema too so the two never disagree.

One primary type per page

Nest related types where it makes sense rather than stacking unrelated blocks that compete for meaning.

Validate before you ship

Run the output through Google's Rich Results Test and the Schema Markup Validator to confirm the values.

Never fake reviews or ratings

Aggregate ratings must reflect genuine, on-page reviews. Fabricated ratings risk a structured-data penalty.

Frequently asked questions

What is schema markup?

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.

What is JSON-LD and why does this tool use it?

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.

Will schema markup improve my rankings?

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.

Where do I paste the generated code?

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.

Is my data uploaded anywhere?

No. Everything runs in your browser. Nothing you type is sent to a server, logged or stored.

Which schema types are supported?

Nine of the most-used: Organization, Local Business, Article, FAQ, HowTo, Product, Event, Person and Website.

How do I know the markup is valid?

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.

Can I add more than one schema type to a page?

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.

Do I need coding skills to use this?

No. You fill in a plain-language form and the tool writes the code for you. Copy it, paste it, done.

Is it really free?

Yes — unlimited use, no account, no watermark, and no limit on how many blocks you generate.
