AEO vs SEO: what's the difference?
SEO (search engine optimization) gets your pages to rank as links on a results page; AEO (answer engine optimization) gets your content extracted and presented as the direct answer by AI engines, voice assistants, and Google's AI Overviews. SEO targets clicks; AEO targets being the cited answer. They share a foundation, so the best strategy runs both together.
SEO optimizes pages so crawlers rank them and humans click — winning on rankings, traffic, and links. AEO optimizes so an answer engine can lift your passage and present it as THE answer, often with no click. As more queries resolve inside an AI answer, ranking a link without being the cited answer means missing that traffic entirely.
The two overlap heavily: clean technical structure, topical authority, schema, and trustworthy content help you both rank and get cited. Where they differ is format — SEO rewards a page built for a query; AEO rewards a self-contained, quotable answer (a 40–65-word lead, question-style headings, clear definitions, comparison tables) a model can extract verbatim.
AEO is closely related to GEO (Generative Engine Optimization): AEO is the broader answer-extraction discipline (including featured snippets and voice), while GEO focuses on generative AI engines specifically. Gigde runs SEO, AEO, and GEO as one combined program (/services/seo-geo) so the same work wins Google rankings and AI citations. Request a free growth plan at contact@gigde.com.
