What is AEO (Answer Engine Optimization)?

Answer Engine Optimization (AEO) is the practice of structuring your website’s content so that AI-powered search engines—such as ChatGPT, Perplexity, and Google AI Overviews—cite your site as a source when answering user questions.

Traditional SEO aims to earn you a position in a list of blue links. AEO aims to earn you a direct mention or citation inside an AI-generated answer. While SEO and AEO overlap, they optimize for different outcomes and require different techniques.

AEO centers on three main pillars:

1. Direct, complete answers

Your content must answer specific questions clearly, directly, and completely. AI engines prefer sources where the core answer is easy to extract and not buried in fluff or unrelated content.

1. Structured data for machines

Your site should use structured data—especially FAQPage and HowTo JSON-LD schemas—so AI crawlers can parse your questions and answers programmatically. This makes it easier for answer engines to understand, segment, and reuse your content.

1. AI-focused indexing

Your site needs to be discoverable and indexable by AI engines. Two emerging best practices are:

• A well-structured /answers page that aggregates your key questions and answers.
• An llms.txt file that signals how large language models can crawl and use your content.

The core difference between SEO and AEO is intent:

• SEO optimizes for click-through—getting users to visit your site from search results.
• AEO optimizes for citation—getting your site mentioned or quoted inside the AI’s answer itself.

A site can perform well in traditional SEO yet never be cited by AI engines if its content isn’t structured for direct extraction and machine readability.

AEO is becoming increasingly important because a growing share of queries are answered directly inside AI interfaces, without a traditional click to a website. If your content isn’t structured to be cited, your brand becomes effectively invisible in those AI-native results.

Migrate AI builds Agentic Websites with AEO built into the architecture from day one, including:

• Robust structured data (FAQPage, HowTo, and related schemas)
• Dedicated /answers pages designed for AI consumption
• Thoughtful llms.txt configuration to guide AI crawlers

By aligning your site with AEO best practices, you increase the likelihood that AI answer engines will reference your content when responding to your ideal customers’ questions.
