Enter your URLs (up to 25), pick a schema type and the properties you need, and get ready-to-use JSON-LD markup in seconds. The AI reads each page's actual content and extracts only the data you specify — giving you full control over your structured data.
Search engines use structured data to understand the content on your pages in a machine-readable way. When you add JSON-LD markup, you give search engines explicit signals about what your content is — a product, an article, a recipe, a local business, an event — rather than making them guess from raw HTML. This directly impacts how your pages appear in search results, enabling rich results like star ratings, pricing, FAQs, event dates, and more.
Without structured data, search engines rely on heuristics to extract meaning, which is probabilistic and often incomplete. With structured data, you are telling them exactly what's on the page.
The output is ready-to-paste <script type="application/ld+json"> markup for each URL, with a clipboard button for easy copying.
Many AI tools will accept a full page and generate schema markup automatically. While convenient, this approach has significant drawbacks:
You lose control over what gets included. Fully automated tools decide for you which properties matter, which schema type to use, and what data to extract. They often produce bloated markup with irrelevant properties, or miss critical ones specific to your use case.
You choose the schema type. A page about a recipe might also mention a restaurant, a person, and a video. You decide which @type is the primary one to mark up, not an AI making a guess.
You choose the properties. If you're marking up a Product, you might want name, price, availability, and aggregateRating — but not 50 other properties the AI thought were interesting. Being selective means your markup is clean, accurate, and relevant to how you want search engines to represent your content.
The AI extracts data, it doesn't invent it. Because you select the properties and the tool constrains the AI to extract from the actual page content, the result is grounded in real data. If a property can't be extracted from the page, it returns null rather than hallucinating a value.
This tool supports the full schema.org vocabulary — nearly 2,000 types with their complete property lists. Whether you need common types like:
...or more specialized types, they're all available.
Once you have the JSON-LD output:
<script type="application/ld+json"> tag, typically in the <head> section (though it's valid anywhere in the HTML)Unlike manual markup creation, this tool processes up to 25 pages at once, extracting and generating schema for each page in parallel. This makes it practical to add structured data across an entire section of your website quickly rather than writing markup one page at a time.
