Schema Markup Generator
Paste any page URL and get schema.org JSON-LD markup with Wikipedia-linked entities — the same approach the paid schema tools use.
What this schema generator does
Paid tools like schemawriter.ai charge $59+ a month to turn a URL into structured data. This tool does the same core job for free: it reads your page, identifies the real-world entities in your content (people, places, organizations, concepts), links them to their Wikipedia pages, and generates a clean schema.org JSON-LD block with those entities in the about and mentions fields.
How to use it
Enter the URL of the page you want to optimize, pick the schema type (Article for blog posts, Product for product pages, LocalBusiness for a business, and so on), and optionally add the keyword you're targeting. Hit Generate, then paste the JSON-LD into your page's <head>. You get three free generations a day — enough to cover a week of content in minutes.
A few tips
Use Article or BlogPosting for blog content, Product for anything with a price, and LocalBusiness for physical businesses. Always run the output through validator.schema.org before publishing, and keep the Wikipedia-linked entities — they're what connects your page to Google's Knowledge Graph.
Frequently asked questions
What is schema markup and why does it matter?
Schema markup (JSON-LD) is structured data you add to a page so Google and other search engines understand exactly what it is — an article, a product, a business, an FAQ. Pages with clear schema are more likely to earn rich results like star ratings, FAQ snippets, and knowledge panel connections.
What is entity-based schema?
Google understands the web through entities — people, places, organizations, and concepts it already has in its Knowledge Graph. This tool links the entities on your page to their Wikipedia pages via sameAs, which helps Google connect your content to topics it already knows and ranks.
Where do I put the generated JSON-LD?
Paste the JSON-LD block into the <head> of your page, or use a plugin like RankMath or Yoast if you use WordPress. You can validate it first at validator.schema.org to confirm there are no errors.
Is this the same as schemawriter.ai?
It's the same idea, free: paste a URL, get schema.org JSON-LD with entity links, ready to paste into your page. No subscriptions, no run limits beyond a few free generations a day.
