Generate schema markup from any URL

The LightSite schema markup generator is a free structured data generator that works from a URL instead of a form. Paste a public page address and it reads the live page the way a crawler does, then returns schema.org JSON-LD built from what is genuinely on the page: the schema type, title, description, headings, author, publication date and language. No account, no API key, nothing stored.

How to generate schema markup for a page

  1. Paste the page address into the generator.
  2. Check the fields it found — if the author or published date is missing, the page itself does not show one.
  3. Copy the JSON-LD block.
  4. Paste it into that page's <head>, or into your CMS field for custom head code. One block per page.
  5. Publish, then confirm with Google's Rich Results Test or the schema.org validator.

How it differs from a form-based structured data generator

Form-based generators assemble JSON-LD from whatever you type, so the markup can describe a page that does not exist. This generator fetches the page, strips navigation, footers, related-post lists and cookie banners, picks the real main content, and recovers dates and bylines that exist only as styled text — including 2024/03/04, 2024.03.04, 2024年3月4日 and Mar 4, 2024. Word counting is CJK-aware, so Japanese and Chinese pages are not reported as thin content. A listing page showing many entry dates and no byline does not borrow the newest entry's date. Fields the page does not show are left out rather than guessed.

What it reports about the page

  • Schema type — Article for a dated, authored piece; WebPage for a standard page.
  • Readable words — the text left after boilerplate is removed.
  • Author and publication date — from meta tags, <time datetime>, or the visible byline.
  • Language — declared, or detected from the script.
  • Existing structured data — whether the page already publishes JSON-LD.
  • JavaScript-only pages — when the server returns an empty shell, the tool says so instead of inventing markup, because crawlers and AI assistants see the same emptiness.

Frequently Asked Questions

What is a schema markup generator?

A schema markup generator turns information about a page into schema.org structured data — usually JSON-LD — that you paste into the page's HTML. Search engines and AI assistants read that block to understand what the page is, who wrote it, and when it was published.

How do I add structured data to my website?

Copy the generated JSON-LD, wrap it in a <script type="application/ld+json"> tag, and paste it into the <head> of that page or your CMS custom-head-code field. Publish, then validate with Google's Rich Results Test.

Can schema markup be generated automatically from a URL?

Yes. This tool reads the published page rather than asking you to fill in a form, so the markup describes what is really there. Keeping markup generated and correct across a whole site, page by page, is what LightSite automates.

Should schema markup be auto-generated?

Auto-generation is safe when it describes the page truthfully. It becomes risky when generated markup claims fake ratings, fake authors, or fake dates. This tool only outputs fields it found on the page.

Which schema type should I use — Article, WebPage or FAQPage?

Article for a dated piece with an author, WebPage for a standard page, and FAQPage only when the visible page really shows questions and answers. The type is chosen from the page structure.

Is the schema generator free?

Yes — free, no account, one page at a time, and nothing you submit is stored.

Does structured data help with AI search?

It makes a page easier to read and reuse: ChatGPT, Claude, Perplexity and Google AI Overviews all crawl HTML, and structured data states a page's facts unambiguously instead of leaving them to be inferred. It is not a ranking trick, and it will not make an assistant cite a page that has nothing to say.
