AEO vs SEO

SEO (Search Engine Optimization) is the practice of ranking a page in a search engine’s list of results. AEO (Answer Engine Optimization) is the practice of being named and cited inside the single answer an AI assistant generates. They share roots but reward different things.

Where they differ

The unit of competition

SEO competes for a position in a ranked list — being #1 to #10. AEO competes to be inside the answer itself. There is no page two; you are either synthesized into the response or you are not.

What gets rewarded

• SEO rewards backlinks, keywords, page speed, and crawlability.
• AEO rewards entity clarity, structured data, liftable question→answer content, and citation-worthy authority.

How success is measured

SEO success is keyword rankings and organic clicks. AEO success is mention rate, answer rank, citation share, and Share of AI Voice across engines like ChatGPT and Perplexity — which is exactly what AEO Pilot measures.

Where they overlap

Good SEO hygiene helps AEO: clean HTML, fast pages, sitemaps and crawl access all matter. But AEO goes further — it asks whether a language model can confidently attribute a fact to your brand and quote you. Schema markup, an entity graph, and FAQ corpora are AEO-first moves that most SEO checklists ignore.

Do you still need SEO?

Yes — but it’s no longer enough. As buyers shift from searching to asking, the brands that win will be the ones optimized for both the link and the answer. AEO Pilot scores and improves the answer half.
