This handles Schema.org structured data detection, validation, and generation with a strong focus on keeping you current with Google's shifting landscape. It knows which schema types are safe to use (Product, Article, LocalBusiness), which are restricted (FAQ is government and healthcare only as of August 2023), and which are dead (HowTo rich results ended September 2023, SpecialAnnouncement retired July 2025). The validation catches common mistakes like missing @context, relative URLs, and placeholder text still in production. It defaults to JSON-LD and includes ready-to-use templates for the most common types. Worth having if you're tired of manually checking which schema types Google actually still supports, since they've deprecated about a dozen in the past two years.
