Schema PraetorBeta
Crawl a website and check the structured data of every page: JSON-LD, Microdata and RDFa, validated against schema.org and Google rich results.
Project: the .json file you saved from the results screen, to reopen an audit later.
What Schema Praetor checks
Each alert says who flags it, so you know what is a real error and what is a nice-to-have.
Unknown types, wrong data types, broken structure: what the schema.org vocabulary does not allow.
Properties required or recommended for rich results, only for the types Google still supports.
Good practices beyond Google and schema.org, from my audits.
JSON-LD, Microdata and RDFa, plus pages without any structured data and blocks that fail to parse.
Business entities found across the site, and issues that span several pages.
An Excel file for people, and a JSON project to give to an AI to rewrite your structured data.
