Schema markup and structured data - often missing on high-ranking sites:
Why schema matters more for AI:
Google uses signals beyond schema (links, authority, engagement). AI systems rely heavily on structured data to:
- Understand content type
- Extract information confidently
- Verify entity information
- Reduce ambiguity
Schema that impacts AI (~10% of Perplexity ranking):
- Article/TechArticle - Content type identification
- FAQPage - Question-answer extraction
- HowTo - Step-by-step processes
- Organization - Entity recognition
- Product/Service - Commercial intent clarity
- BreadcrumbList - Site hierarchy understanding
Implementation checklist:
{
"@context": "https://schema.org",
"@type": "Article",
"headline": "Your Page Title",
"datePublished": "2026-01-06",
"dateModified": "2026-01-06",
"author": {
"@type": "Person",
"name": "Author Name",
"url": "https://yoursite.com/author"
},
"publisher": {
"@type": "Organization",
"name": "Your Company"
}
}
Common mistakes:
- Schema that doesn’t match visible content
- Outdated dateModified timestamps
- Missing author/publisher info (E-E-A-T signals)
- No FAQPage schema on FAQ sections
