Why it matters
Structured data makes entities, authorship, dates and breadcrumbs explicit for Google features and for systems that extract facts. Google says it isn't required for AI features, so this is informational.
How to fix it
Add the schema that matches the page type: BlogPosting/TechArticle + BreadcrumbList for content, Product or SoftwareApplication only with real visible data, ProfilePage for authors.
