Schema Markup Tools
See what structured data a page declares, then build what is missing.
2 tools · Real Data
Structured data is a small block of code, usually JSON-LD, that tells search engines in a fixed vocabulary what a page is about: this is an article by this author, this is the organization behind the site, this is a local business at this address. It does not change what visitors see, but it gives machines an unambiguous description to work with, and many rich result formats in search are built from it.
This hub has two tools that work as a pair. The Schema Checker fetches a live page and lists every JSON-LD and Microdata type it finds, so you can confirm what is actually deployed rather than what a plugin claims to output. The Schema Generator does the opposite job: fill in a short form and it returns a JSON-LD block for an Organization, WebSite, Article or LocalBusiness, ready to paste into the page head.
A simple routine: check the homepage and one template of each page type first, note which types are missing or duplicated, generate the missing blocks, deploy them, and run the checker again to confirm the markup now appears on the live page. Keep every value identical to what visitors see on the page. Detecting a type is not the same as qualifying for a rich result, so for eligibility questions also test the page in Google’s own Rich Results Test.

Frequently asked questions
What is schema markup?
Schema markup is structured data written in the schema.org vocabulary and added to a page’s HTML, most often as a JSON-LD script. It labels things like the organization, the author, the article date or a business address so search engines and AI systems can read them without guessing from the surrounding text.
How do I check which schema a page has?
Enter the URL into the Schema Checker. It loads the live page, reads every JSON-LD script and every Microdata itemtype, and lists the types it found. If it finds none, it says so clearly, which usually means the markup is missing or is added by scripts after load and is not in the delivered HTML.
Which schema types can I generate here?
The Schema Generator builds JSON-LD for four common types: Organization, WebSite, Article and LocalBusiness. You enter a name plus an optional URL, logo or image and description, and it returns a block you can copy into your page. For other types, use the output as a pattern and follow the schema.org documentation for the extra properties.
Does adding schema improve rankings?
Google does not describe structured data as a general ranking boost. What it does is make a page’s content explicit and, for supported types, make the page eligible for richer search appearances. Eligibility is not a promise: the markup has to match the visible content and follow each feature’s guidelines, and search engines still decide whether to show it.
