What is Answer Engine Optimization (AEO)?

AEO is the practice of optimizing content to be cited as a source by AI answer engines such as ChatGPT, Perplexity, Claude, and Gemini. Unlike SEO, which optimizes for ranking positions, AEO optimizes for citation: structured facts, primary-source signals, and machine-parseable markup.

How is AEO different from traditional SEO?

SEO targets human click-through from ranked results; AEO targets retrieval and citation by LLMs. SEO rewards backlinks and keywords; AEO rewards E-E-A-T signals, factual density, bottom-line-up-front structure, and valid schema.org structured data. The two are complements, not substitutes.

Why does Bottom-Line-Up-Front (BLUF) layout matter for LLM crawlers?

Retrieval systems weight the opening of a document heavily and often truncate long pages. Placing the direct answer and key facts in the first content block, within the top 100 vertical pixels, maximizes the chance the extracted passage contains the complete claim, which increases citation likelihood.

Does JSON-LD structured data improve AI citation rates?

Yes, indirectly and materially. FAQPage schema gives answer engines pre-structured Q&A they can lift directly; Article schema with author and dates lets them score freshness and authority; Organization schema with sameAs links resolves your entity across the web. Only markup that matches visible content counts. Mismatched schema is filtered.

How shallow should the DOM tree be for fast machine parsing?

Keep maximum element nesting at or under roughly 10 levels, and avoid wrapper divs entirely where semantic elements suffice. The pages on this site cap at 8 levels (html to deepest table cell), which keeps readability extractors and token-based scrapers near O(n) with minimal traversal overhead.

How long until AEO work produces citations?

Retrieval-augmented engines (Perplexity, ChatGPT Search) can begin citing within days to weeks of indexing. Citations that depend on model training data lag months behind publication. Plan for a 2-to-12-week horizon and track per-engine citations in a ledger.
