  "@type": "FAQPage",
  "mainEntity": [{
    "@type": "Question",
    "name": "...",
    "acceptedAnswer": { "@type": "Answer", "text": "..." }
  }]
}

// Product, LocalBusiness, BreadcrumbList, HowTo, etc.

Common Schema Types

<meta property="og:description" content="..." />
<meta property="og:image" content="https://...1200x630.jpg" />
<meta property="og:url" content="https://..." />

AI Search Engine Optimization (AEO)

AI-powered search platforms (ChatGPT, Perplexity, Google AI Overviews) require additional optimization:

Content for AI Discoverability

• Direct answers: Start sections with clear, concise answers to questions
• Structured format: Use lists, tables, definitions that AI can extract
• Authoritative sourcing: Cite data, studies, expert opinions
• Comprehensive coverage: Cover topics thoroughly - AI prefers complete sources
• Clear attribution: Make authorship, expertise, and date clear
• FAQ sections: Include common questions with direct answers

Technical for AI

• Clean HTML semantics (AI parsers prefer semantic markup)
• Structured data (Schema.org) helps AI understand content
• RSS/Atom feeds for content syndication
• llms.txt file at site root for AI crawlers
• No content behind login walls or aggressive paywalls
• Fast, reliable responses (AI crawlers have low timeout thresholds)

Content Strategy

Keyword Research Process

1. Seed keywords from business goals
2. Expand with related terms, questions, LSI keywords
3. Analyze search intent (informational, navigational, commercial, transactional)
4. Check competition and difficulty
5. Map keywords to pages (1 primary + 2-3 secondary per page)
6. Identify content gaps vs competitors
