Structured Data bridges the gap between human content and machine understanding. While AI has become better at interpreting unstructured text, structured data provides explicit signals that remove ambiguity. For AI-SEO, structured data helps AI systems understand exactly what your content represents, who created it, and how it relates to other entities.
Common Structured Data Types
- Organization: Company information, logo, contact details.
- Article: Author, publication date, headline, description.
- FAQ: Question-answer pairs for direct extraction.
- HowTo: Step-by-step instructions with tools and materials.
- Product: Pricing, availability, reviews, specifications.
- Person: Name, role, affiliation, expertise.
Structured Data Formats
| Format | Implementation | Recommendation |
|---|---|---|
| JSON-LD | Script tag in head/body | Preferred by Google |
| Microdata | HTML attributes | Good for inline content |
| RDFa | HTML attributes | Less common today |
Why Structured Data Matters for AI-SEO
- Explicit Semantics: Removes guesswork—AI knows exactly what content represents.
- Entity Connection: Links content to knowledge graphs and known entities.
- Rich Results: Enables enhanced SERP features and AI citations.
- Trust Signals: Author markup and organization data build credibility signals.
- Extraction Ease: Pre-structured information is easier for AI to use accurately.
“Structured data is like providing AI with a cheat sheet. Instead of inferring what your content means, AI knows exactly what it represents and how to use it.”
