This validates the structure of the pasted block only. It does not guarantee a rich result or check a live page.

Frequently asked questions

How is this different from the eligibility checker?

This checks JSON-LD structure, while the eligibility checker checks required fields per rich-result type.

Does it check live pages?

No. Paste the block yourself; nothing is read live.
