AEO vs SEO: what’s the difference?
SEO optimises to rank your pages in a list of search results. AEO optimises to be the source an AI engine cites when it answers a question directly. They share foundations — quality content, structured data, authority — but AEO focuses on entity clarity and citations across AI platforms rather than clicks from a results page.
The core difference
SEO and AEO both make your brand more discoverable, but they aim at different end-states. SEO wins a position in a ranked list a user clicks. AEO wins a citation inside the synthesised answer a user reads — often without any click at all.
What they share
- High-quality, accurate content that genuinely answers questions.
- Structured data (schema) that helps machines understand your pages.
- Authority signals — credible mentions, citations and a clear brand entity.
- Fast, crawlable, well-organised websites.
Where they diverge
- Goal: SEO = rank & click; AEO = be cited in the answer.
- Content shape: SEO rewards depth and keywords; AEO rewards direct, quotable answers up front.
- Measurement: SEO tracks rankings and traffic; AEO tracks share of answer and citations across engines.
- Surfaces: SEO targets Google/Bing results pages; AEO targets ChatGPT, Perplexity, AI Overviews and Gemini.
Do you need both?
Yes. Strong SEO foundations help AEO — but they don’t guarantee citations, because answer engines weigh entity clarity and structured data differently. The brands winning today treat AEO as the layer that sits on top of solid SEO. New to AEO? Start with What is Answer Engine Optimization?
