Glossary Page Strategy for AEO: Earning AI Citations for Definition Queries at Scale
A glossary page defines industry terms in a structured format that AI systems can easily find and cite. When someone asks ChatGPT or Perplexity 'what is [industry term]?', they often get answers from glossary pages that have defined the term clearly. A well-structured glossary with proper schema markup can earn dozens of AI citations for definition queries - one per term - with a single content investment.
Glossary pages are one of the most underused AEO content formats. They systematically target the high-volume definitional query pattern ('what is X', 'X definition', 'meaning of X') using DefinedTerm schema - the specific schema type designed to signal authoritative definitions to AI systems. A 50-term glossary with proper implementation creates 50 independent citation opportunities.

{
"@context": "https://schema.org",
"@type": "DefinedTerm",
"name": "Net Revenue Retention",
"description": "Net revenue retention (NRR) measures the percentage of revenue retained from existing customers over a period, including expansion revenue from upsells and contraction from downgrades and churn.",

}Pros
- Each term page can independently rank for '[term] definition' queries
- Deep semantic content per term (formula, examples, benchmarks)
- FAQPage schema alongside DefinedTerm for Q&A extraction
- Easiest for AI crawlers - one concept per URL, maximum directness
Cons
- High page count to maintain (100+ terms = 100+ pages)
- Internal link complexity across glossary hub and term pages
