How is AEO different from SEO?

Traditional SEO optimises for Google keyword rankings using backlinks and page authority. AEO optimises for AI engine citations using structural signals — schema markup, content clarity, and technical accessibility for AI crawlers. The ranking signals are completely different.

What are the main AEO checks?

The main AEO checks include: FAQ schema and visible Q&A content, heading hierarchy (H1/H2 structure), direct-answer prose, schema.org structured data, AI crawler access in robots.txt, llms.txt, meta description quality, semantic HTML structure, freshness signals, and E-E-A-T trust signals.

Definition

Answer Engine Optimization (AEO) is the discipline of structuring web content — through technical signals, schema markup, content clarity, and AI crawler access — so that AI search engines can reliably extract, cite, and recommend it in response to user queries.

Why AEO matters

AI search engines like ChatGPT, Perplexity, and Google's AI Overviews now answer millions of buyer queries every day. When a buyer asks “what is the best AEO tool” or “how do I improve my AI citation score”, the AI engine synthesises an answer from the sources it has indexed and trusts. Whether your brand appears in that answer depends on how well your content passes AEO checks.

Unlike traditional SEO — which uses backlinks and keyword density as ranking signals — AEO relies on structural and semantic signals that allow AI systems to extract specific passages, quote them accurately, and attribute them to your brand. A page that scores well on traditional SEO but fails AEO checks may rank highly in Google while being completely invisible in AI search.
