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.
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.
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.
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.
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.
