Syntax + structure
Confirms the JSON parses, has a schema.org @context, and exposes a @type — the three things that break most often.

Schema Markup Validator
Paste JSON-LD (or a full script tag) and we validate the syntax, list the types found, and flag missing recommended properties per type.
What this tool checks
Eligibility, not a guarantee
Valid markup makes you eligible for rich results; it never guarantees one. We flag missing recommended props, not Google's decision.
This tool sees your page from the outside
The free Aetos plugin sees inside your WordPress.
This tool checks what a bot sees from a public URL. The free Aetos edition runs a real audit from inside WordPress — across your pages and WordPress environment — so it catches signals an outside view cannot see.
Free edition, no card. Pro adds additional analysis modules, exports, and the AI fix assistant. Want us to do it for you? Talk to the team → Talk to the team
FAQ
Common questions
Does this replace Google's Rich Results Test? +
No. It is a fast in-browser syntax + structure check. For official rich-result eligibility, also run Google's Rich Results Test and Schema.org validator.
Can I paste a whole <script> tag? +
Yes — we extract the JSON-LD from inside a <script type="application/ld+json"> block automatically.
Why does it warn about missing properties? +
Each type has properties Google recommends for rich results (e.g. Product needs offers). Missing ones reduce eligibility, so we surface them.
