What's the difference between SEO and AEO?
SEO (search engine optimization) competes to rank your page in a list of links on Google. AEO (answer engine optimization) competes to make your content the answer an AI engine quotes — where there is no list and no page two, just a handful of cited sources.
SEO and AEO share a foundation but optimize for two different outcomes.
SEO is about ranking. When someone searches Google, they see a ranked list of blue links, and SEO is the work of climbing that list — keywords, backlinks, page speed, and content that earns clicks. The prize is a high position among many links.
AEO is about being the answer. When someone asks ChatGPT, Perplexity, or triggers a Google AI Overview, they get one synthesized answer that cites only a few sources. AEO is the work of being one of those cited sources. There's no page two to settle for — you're either in the answer or you're invisible.
The tactics overlap more than they differ. Both reward clear, well-structured, trustworthy content. AEO leans harder on direct question-and-answer formatting, FAQ and structured-data schema, and specificity, because a model has to be able to lift your answer cleanly. And SEO still cares about traditional signals — links, authority, technical health — that AEO benefits from too.
For most small businesses the right move isn't to choose. It's to write content once, structured so both a search crawler and an AI engine can use it — so the same page ranks on Google and gets quoted by the AI tools your customers increasingly ask first. Generative engine optimization (GEO) and LLM SEO are closely-related terms for the AI-facing side of this same work.
Common questions
Should I do SEO or AEO first?
Do them together. The content discipline is largely the same; structuring a page well for AI answers also helps it rank in traditional search. Splitting them into separate projects usually wastes effort.
Is AEO the same as GEO?
Nearly. AEO (answer engine optimization) is about being the answer in any answer engine; GEO (generative engine optimization) focuses on getting cited inside the text a generative model writes. In practice the work overlaps almost entirely.
Does AEO replace SEO?
No. It extends it. Traditional search isn't going away, but a growing share of people ask an AI tool first — so you want to be found in both places, which the same well-structured content can do.
