Frequently asked questions

Is Schema JSON-LD Validator free to use?

Yes. Schema JSON-LD Validator is available on the free plan with 20 daily runs. Paid plans add higher quotas for repeat work.

Why is my JSON-LD not producing rich results?

Valid syntax is not enough. The properties have to meet the type's requirements, and the marked-up content must be visible on the page.

Does JSON-LD have to be in the head?

No. It can appear anywhere in the document, including in the body, as long as the block is complete.

Can I use several JSON-LD blocks?

Yes, and it is often clearer to. Use one block per entity and connect them with @id references.

What does an unescaped character do to JSON-LD?

It breaks the whole block, so every entity in it is lost at once. A single stray quote can cost you all the markup on the page.
