AEO (Answer Engine Optimization) is the practice of structuring content so that answer engines — ChatGPT, Claude, Perplexity, and Google AI Overviews — quote or paraphrase it directly inside the synthesized answer a user reads. Where SEO competes for a position on a results page, AEO competes to be the sentence the AI says out loud.
The mechanics are concrete: write in a question-then-direct-answer shape, ship FAQ JSON-LD so the question and answer are explicitly linked, keep facts current and dated, and make the page crawlable to AI bots. Answer engines reward content that is unambiguous, well-structured, and easy to lift a single clean claim from.
AEO sits inside the broader AIO umbrella alongside GEO. For a brand with little backlink authority, AEO is the asymmetric move — structural signals like schema and llms.txt matter far more to answer engines than the link graph that gatekeeps traditional Google rankings.

Frequently asked
What is the difference between AEO and SEO?
SEO optimizes for ranking on a search results page; AEO optimizes for being the synthesized answer an AI engine returns. They share tactics (structured content, clear headings) but target different surfaces. Most teams do both — SEO for Google's links, AEO for the AI answer box.
Is AEO the same as GEO?
Closely related. AEO emphasizes being the answer; GEO (Generative Engine Optimization) emphasizes being cited as a source. In practice the work overlaps heavily: structured, question-shaped content with schema and open crawler access serves both.
What's the fastest AEO win?
Add FAQ JSON-LD to your top three pages with direct, self-contained answers, then make sure AI crawlers can reach them in robots.txt. Both are afternoon jobs and tend to lift AI citation rates within weeks.
