Answer Engine Optimization (AEO)

End-to-end practice of optimizing content to be cited by LLMs when they generate answers. Covers the technical foundations (how LLMs select sources), content structuring patterns (Q&A schema, citation-worthy patterns), measurement (which content gets cited, by which LLM, how often), and the strategic positioning that differentiates AEO from traditional SEO and from AI-SEO.

This skill is provider-aware but provider-agnostic: works for content optimized for ChatGPT, Claude, Perplexity, Gemini, Copilot, and emerging AI surfaces.

When to use this skill

AEO vs SEO vs AI-SEO

Three distinct (but overlapping) practices. Confusing them leads to wasted investment.

Strategic positioning

For most B2B brands:

• Traditional SEO: still 50-70% of organic traffic. Don't abandon.
• AI-SEO: emerging 10-20% of search-driven engagement. Growing fast.
• AEO: 5-15% of LLM-mediated user discovery. Largest growth potential.

Optimize content for all three simultaneously; the techniques substantially overlap.

The AEO funnel

Users find brands through LLMs in a different funnel than search:

Traditional search:           AEO funnel:
1. User types query           1. User asks LLM a question
2. SERPs show ~10 results     2. LLM generates answer
3. User clicks one            3. LLM cites N sources (1-10)
4. User reads page            4. User reads answer; may click cited source
5. User converts              5. User attributes answer to LLM (less so to cited brand)

Key implications:

• Citation is the new click. When LLM cites your content, you don't always get a visit — but you get attribution.
• Brand-as-source becomes the goal. Even without click, being cited builds brand association.
• Quality > volume. LLMs cite a small number of sources; quality of citation matters more than ranking position.
• Trust signals matter more. LLMs avoid citing low-authority sources.

See references/aeo-fundamentals.md for the deep mechanics of how LLMs select sources, the citation models per provider, and the trust signals that drive selection.

The 5 content patterns that get cited

After analysis of LLM citation behavior, five content patterns dominate:

Pattern 1: Definitional content with clear claims

LLMs cite sources for definitions, facts, and short claims. Pages that answer "What is X?" with a clean 2-3 sentence definition followed by elaboration get cited often.

Structure:

[Term] is [crisp definition in 1-2 sentences].

[Elaboration with context and nuance — 1-3 paragraphs].

[Related concepts / scope / boundaries — optional].

Pattern 2: Comparative tables

LLMs use tables to extract comparisons. Markdown tables in published content (or HTML equivalents) get cited when users ask "X vs Y."

| Feature | Product A | Product B |
|---------|-----------|-----------|
| Price | $X | $Y |
| Speed | Z ms | W ms |
| Support | 24/7 | Business hours |

Pattern 3: Step-by-step procedural content

"How to [task]" content with explicit numbered steps. LLMs reproduce procedural steps; the cited source becomes the authoritative reference.

Pattern 4: Statistics + data with sources

LLMs cite content that provides numerical facts with attribution. "According to [your study], X% of [thing] does Y" is repeatable and citable.

Pattern 5: Lists with explanations

"Top N approaches to X" with each item explained gets cited when users ask comparative or enumeration questions.

See references/llm-content-structuring.md for deep patterns including FAQ schema, citation hooks, voice-search optimization, and LLM-readable structure markers.

Clarify First

Before generating, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• Target queries — the actual questions customers ask LLMs about your category (drives which content to audit and restructure)
• Your brand name — exact wording to track in answers vs competitors (drives citation extraction)
• Target LLM surface — ChatGPT / Claude / Perplexity / Gemini (citation behavior and trust signals differ per provider)
• Canonical page/content — the high-value page to be the authoritative source (drives schema generation + pattern restructuring)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Quick start

1. Audit existing content: python3 scripts/aeo_content_auditor.py --path ./content
2. Add Q&A schema to high-value pages: python3 scripts/schema_qa_generator.py --content article.md
3. Track citations from competitors: python3 scripts/citation_extractor.py --query "What is X?" --brand "Your Brand"
4. Iterate: monthly content review with AEO scoring

End-to-end workflows

Workflow: AEO content strategy from scratch

1. Identify target queries — what questions do potential customers ask LLMs about your category?
2. Audit competitor citations — which brands get cited for those queries? scripts/citation_extractor.py
3. Audit your existing content — score current content for AEO patterns: scripts/aeo_content_auditor.py
4. Prioritize 10-20 high-value pages — those that should be the canonical source
5. Restructure per AEO patterns — definitional content, tables, step-by-step, statistics
6. Add structured data (optional) — scripts/schema_qa_generator.py generates FAQ schema; the visible Q&A structure matters more than the markup (Google retired FAQ rich results in May 2026 and says no special schema is needed for AI features)
7. Build authority signals — backlinks, citations, mentions
8. Monitor monthly — track citation rate trend

Workflow: Audit individual content piece

1. Run scripts/aeo_content_auditor.py --path article.md --format markdown
2. Review per-pattern scoring (5 patterns above)
3. Identify gaps: missing definition, no table, no clear steps, no stats, no list
4. Restructure to add 2-3 missing patterns
5. Optionally add FAQ schema with scripts/schema_qa_generator.py (no Google rich result; low impact)
6. Re-audit to confirm improvements

Workflow: Competitive citation analysis

1. Identify 10-20 key queries in your category
2. Query each LLM (ChatGPT, Claude, Perplexity, Gemini) with those questions
3. Record citations + brands mentioned
4. Analyze: which brands dominate? what content do they have?
5. Identify white-space queries (no clear dominant source yet)
6. Prioritize content creation for white-space queries

Workflow: Measure AEO performance

1. Citation rate: % of queries where your brand is cited (target: 30%+ for category leaders)
2. Brand mention rate: % of queries where your brand is mentioned (cited or not)
3. Source quality: are you cited as primary source or supporting?
4. Click-through from citations: traffic attributable to LLM citations (requires source tracking)
5. Voice tracking: how is your brand characterized (positive / neutral / negative attributes)

See references/citation-tracking-and-measurement.md for measurement methodologies, attribution challenges, and competitive benchmarking.

Common AEO failures

• Optimizing only for Google SERP: misses the LLM citation surface entirely
• Generic content without specific claims: LLMs prefer specific, factual content over generic explanation
• No structure markers (headings, lists, tables): LLMs can't extract specific information
• No visible Q&A structure: answers buried in prose instead of question headings with direct answers (the markup alone does not help — Google states no special schema is required for AI Overviews / AI Mode, as of September 2026)
• Stuffed keyword content: LLMs prefer natural language with clear meaning
• No authority signals: LLMs avoid citing low-trust sources
• Outdated content: LLMs prefer recent, current content
• Hidden behind paywalls: LLMs can't cite what they can't access
• No structured data: missed opportunity for richer extraction
• Brand-first content: LLMs prefer informational content over promotional

LLM-by-LLM citation behavior

Different LLMs have different citation behaviors:

Optimize content with structure markers (headings, lists, tables) and authority signals (links, citations, expert attribution) — works across all of these.
