What is Schema Validation?
Schema validation checks whether your page has correct JSON-LD structured data markup. AI engines like Gemini and Google AI Overviews rely heavily on schema.org markup to understand what your content is about, who wrote it, and how to categorize it. Pages with correct schema markup receive up to 12% richer search results.
The validator counts schemas found, checks their validity, and identifies missing required properties. Having 2+ valid schemas (e.g., Article + BreadcrumbList) significantly improves how AI engines interpret your content in your GEO-Score.
Essential Schema Types
Different schema types serve different purposes. The most impactful for AI visibility are:
Article / WebPage
Basic page identification. Include headline, author, datePublished, dateModified. Required for Google AI Overviews.

Organization
Author/publisher identity. Critical for E-E-A-T signals and entity recognition.
BreadcrumbList
Navigation context. Shows AI engines where your page sits in your site hierarchy.
