Free schema checker

Free schema checker is an online tool from Cirvgreen for testing a page’s structured data. It checks a pasted URL against Google’s own Rich Results Test and shows whether the page is eligible for rich results, with no account or email required.

The checker reads JSON-LD, Microdata, and RDFa. It reports which schema types Google detected, along with the exact properties Google parsed, and it surfaces required-property errors and warnings that may prevent a page from qualifying for rich results. The page also presents AI readability as a separate function: Cirv Sight scores how readable a page is to AI crawlers such as ChatGPT, Claude, and Perplexity. The page describes the Rich Results Test as the validator and Cirv Box as the generator.

A URL is pasted into the form to begin, and the Rich Results Test opens in a new tab with the URL pre-filled. The checker is free to use. If markup is broken or missing, the Schema Audit service can fix it; that implementation service is listed as starting from $499 one-time. The page also points to a free plugin, and the site identifies Cirvgreen as a digital tools company based in Dubai, built publicly since 2024.
