What is Schema.org Mistakes Quickstart about?
Schema.org Mistakes Quickstart is subtitled Schema.org. Structured data fails in a handful of predictable ways, and this quickstart names the ten that keep turning up in real audits. It is written for anyone responsible for a website who wants to understand and repair their own schema, from small business owners to marketers and developers who inherited markup they did not write. Each defect is explained as a mechanism, not a rule, so you learn why it breaks rather than memorizing a fix you cannot apply next time.
