Answer Engine Optimization (AEO)

Definition

AEO targets inclusion in answer engines (ChatGPT, Perplexity, Microsoft Copilot, Google AI Overviews, Grok). Where SEO competes for SERP rank, AEO competes for citation share. Technical foundation overlaps heavily with SEO — crawlable HTML, structured data, semantic clarity — but content shape (clear answers, citation-ready facts) and measurement differ.

When to use

• Editorial content that defines, compares, or recommends — exactly the queries answer engines summarize.
• Technical documentation where answer engines already pull citations from your space (check Perplexity, ChatGPT references).
• Topics with high informational intent and low transactional intent — best AEO surface area.
• When a measurable share of brand-search clicks now lands inside AI answer blocks instead of organic results.

Common pitfalls

• Writing for ranking only — answer engines extract paragraphs and lists, not full SERP titles.
• Hiding the canonical definition behind preamble — put the one-sentence answer at the top of the section.
• Mixing brand voice and citation-ready facts — when a paragraph is half opinion, extraction confidence drops.
• Treating AEO as a separate channel rather than a rewriting of the same pages with citation hooks.

Verification

• Search "what is [your topic]" inside ChatGPT, Perplexity, Claude — confirm your domain appears among sources.
• Server logs: GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot must show steady 200 responses on top topical pages.
• Brand-search query trend in GSC — flat or rising while click-through-rate drops often indicates AI answer-block displacement.
• Snippet test: pull the first 60 words of each section into a plain-text reader — does it stand alone as an answer?
