The schema you have. And the schema you should have.

Most tools check whether your markup is valid. This one reads your page, measures it against the entire schema.org vocabulary, and tells you which types your content clearly justifies but nobody ever added — with a paste-ready snippet for each. Free, no signup.

// How it works

Three passes over one page.

  1. What is there. Every JSON-LD block is parsed, every type and property catalogued, and anything that fails to parse is flagged — broken markup is worse than none.
  2. How deep it goes. For each type in use, how many of the properties schema.org actually defines for it are populated, and which high-value ones are missing.
  3. What is missing entirely. The page content is scanned for signals — question headings, testimonials, embedded video, prices, addresses, bylines, step sequences — and each one that has no matching markup becomes an opportunity with a snippet.
// Straight answers

Before you ask.

How is this different from a schema validator?

Validators tell you whether the markup you already wrote is syntactically valid. This tells you what you never thought to write. It reads the page — an FAQ section, testimonials, an embedded video, prices, an address, a byline — and names the schema types those signals justify but your markup is missing.

What does "of available properties" mean?

Every schema.org type inherits properties from its parents; Organization alone has well over a hundred valid properties. Most sites populate five or six. The tool measures your usage against the full vocabulary so you can see the gap, then flags the specific properties that actually earn something.

Should I add every property it lists?

No. More markup is not better markup — inaccurate or padded structured data is a liability. Add the properties that are true, verifiable, and useful to a reader or a machine. That is why the tool separates high-value gaps from raw coverage.

Does more schema mean better rankings?

Not directly. Structured data earns eligibility for rich results and makes your content easier for machines to interpret and cite. That is the mechanism — clarity and eligibility, not a ranking bonus.
