AEO: optimizing for ChatGPT, Perplexity, and Gemini
7 min
AEO (Answer Engine Optimization) aims to get your content cited by AI answer engines like ChatGPT, Perplexity, and Gemini. The levers: answer questions directly and clearly, structure with lists and FAQs, back up claims with sourced data, and exist as a recognized entity. It is the extension of SEO for a web where users get their answer without always clicking through.
Your customers now ask their questions to AI assistants. AEO means becoming the source these engines choose to cite. Here is how.
AEO, SEO, GEO: the distinctions
These disciplines overlap but target different surfaces. Understanding them prevents confusion.
- SEO: being visible in Google's classic organic results.
- GEO: being cited in generative responses, including AI Overviews.
- AEO: being the answer chosen by answer engines (ChatGPT, Perplexity, Gemini).
- The common thread: clear, structured, reliable content recognized as authoritative.
AEO techniques
Answer engines favor content that is easy to extract and cite. You write to be 'quoted,' not just read.
- Formulate a direct, self-contained answer at the start of each section.
- Structure with questions and answers, lists, and definitions.
- Cite precise figures with their source as a mark of reliability.
- Cover the follow-up questions a user might chain together.
- Keep content up to date, dated, and factually accurate.
A growing share of searches ends without a click to a website, the answer being provided directly by the engine or the AI assistant.

Becoming a trusted source
AI systems cite the sources they judge reliable. Your entity reputation and expertise therefore matter as much as the form of the content.
Reinforce your E-E-A-T (experience, expertise, authority, trustworthiness): identified authors, verifiable data, brand consistency, and mentions on recognized sources.
FAQ
How do you know if ChatGPT or Perplexity is citing you?
Regularly test your key queries in these tools and observe the cited sources. Perplexity displays its references transparently; for others, you need to query directly and track how mentions evolve.
Does AEO reduce traffic to my site?
The click count may fall since the answer is sometimes given in place. But being cited as a source strengthens your brand awareness and captures users who want to go deeper. It is better to be the cited source than to be ignored.
