AEO (AI Engine Optimization)
What is AEO?
AEO (AI Engine Optimization) is the practice of optimizing your content so that answer engines — such as ChatGPT, Gemini, and Perplexity — are more likely to adopt your information as a trusted source when generating responses.
While traditional SEO aims to rank at the top of Google search results, AEO focuses on getting your information cited and recommended when AI generates its answers.
From “Search” to “Answer” — How Information Reaches People Has Changed
The rise of ChatGPT and Gemini has fundamentally changed how users find information.
| Before (SEO Era) | Now (AEO Era) |
|---|---|
| Search by keyword | Ask AI in natural language |
| Click a link to visit a site | AI presents the answer directly |
| Compare and judge information yourself | Read the answer AI has summarized |
| Site traffic is generated | Often resolved with zero clicks |
Because of this shift, sites that rank well in SEO but are never cited by AI risk losing their visibility entirely.
3 Key Approaches to AEO
1. Structured Information
Use Schema.org (structured data) to help AI accurately understand the meaning of your content. Marking up FAQs, reviews, person information, and organization details makes your content easier for AI to cite.
2. Visibility of E-E-A-T (Expertise and Trustworthiness)
AI places enormous importance on who is providing the information. The core of AEO optimization is making the following clear:
- Author profile (years of experience, track record, qualifications)
- Organization information (business name, address, contact details)
- Primary information (firsthand experience, case studies)
- External mentions and backlinks
3. Conversational Content Design
Design your content at a “granularity” that AI can easily cite as part of its responses. Specifically:
- Build out FAQ pages in Q&A format
- Structure paragraphs to answer one question concisely
- Write in natural, readable language
- Include statistics, data, and specific figures
The Relationship Between SEO, AIO, and AEO
At our lab, we position the three types of optimization as follows:
- SEO — Building the foundation to be evaluated by search engines like Google
- AIO — General optimization to be cited when AI generates responses
- AEO — Structural and technical optimization specifically targeting AI answer engines
These three are not in competition — they are layered progressively on top of one another. AIO and AEO deliver results only when built on a solid SEO foundation.
