What is AEO (Answer Engine Optimization)?

When someone asks ChatGPT, "What’s the best CRM for startups," the answer comes back as a curated list of recommendations — with specific brand names, reasons why, and sometimes links to sources. No blue links. No scrolling through 10 results. Just a direct answer.

The brands that show up in that answer didn’t get there by accident. They got there because their content, their third-party mentions, and their digital presence are structured in a way that AI engines can understand, trust, and cite.

That’s what AEO is about.

AEO - Answer Engine Optimisation is the practice of optimising your brand’s presence so that AI-powered answer engines like ChatGPT, Perplexity, Gemini, and Google AI Overviews mention, recommend, and cite you when users ask questions in your category.

How AEO differs from traditional SEO

SEO and AEO solve different problems in different ways.

With traditional SEO, you’re optimising to appear in a list of links. The user sees 10 results, clicks one, and lands on your website. Your success metric is ranking position and click-through rate.

With AEO, there is no list of links. The AI engine generates a direct answer that often includes brand recommendations, product comparisons, and sourced citations - all within the response itself. The user may never visit your website. Your success metric is whether you’re mentioned at all, how prominently, and whether AI cites your content as a source.

Here’s what that means in practice:

• SEO targets keywords in Google’s index. AEO targets the questions people ask AI assistants.
• SEO success = ranking on page 1. AEO success = being named in the AI’s answer.
• SEO is driven by backlinks, domain authority, and on-page optimisation. AEO is driven by citation sources, structured content, third-party mentions, and content clarity.
• SEO gives you a click. AEO gives you a recommendation, which carries more trust.

This doesn’t mean SEO is dead. Far from it. Most AI engines use search tools to retrieve data, so strong SEO still feeds AI visibility. But AEO adds a layer that SEO alone can’t cover.

AEO vs GEO: what’s the difference?

You’ll hear both AEO and GEO (Generative Engine Optimisation) used in this space. They’re closely related but not identical.

AEO focuses on appearing in AI-generated answers - the direct responses that tools like ChatGPT and Perplexity give when users ask questions. The emphasis is on being the answer.

GEO is broader. It covers optimising for all types of generative AI outputs — not just Q&A answers but also AI-powered summaries, shopping recommendations, AI Overviews in Google, and AI agent interactions. GEO includes AEO but extends to the full spectrum of AI-generated content.

In practice, most tools and practitioners use the terms interchangeably. If someone says they’re doing AEO or GEO, they’re usually talking about the same core activity: making sure AI engines mention and recommend their brand.

How do answer engines work?

Understanding how AI engines generate answers helps you optimise for them.

When a user asks ChatGPT a question like "best project management tools for remote teams," here’s what happens behind the scenes:

1. Query interpretation - The AI parses the intent behind the question. It identifies the category (project management), the context (remote teams), and the intent (product recommendations).
2. Information retrieval - Depending on the engine, it either draws from training data (ChatGPT), searches the web in real-time (Perplexity), or uses a combination (Gemini, AI Overviews). Each engine has a different retrieval behaviour.
3. Source evaluation - The engine assesses which sources are trustworthy and relevant. This is where citation behaviour matters. Review sites like G2, community platforms like Reddit, comparison articles, and official product pages all get weighted differently by different engines.
4. Answer generation - The engine synthesises information from multiple sources into a coherent answer, often naming specific brands, listing pros and cons, and providing citations or links. Your goal with AEO is to be present at each of these stages - appearing in the right sources, with clear and structured content, so the AI engine has both the reason and the evidence to recommend you.

How to optimise for answer engines

AEO isn’t a single tactic. It’s a set of practices that make your brand citable, trustworthy, and visible to AI engines.

1. Get mentioned on sources AI trusts - AI engines cite specific types of sources heavily: review platforms (G2, Capterra, TrustPilot), community forums (Reddit, Quora), comparison articles, and authoritative publications. If your brand isn’t present on the sources AI cites in your category, you won’t get recommended. Start by identifying which sources matter for your niche and building a genuine presence there.
2. Structure your content for AI consumption - AI engines extract information more reliably from well-structured content. Use clear headings, question-and-answer formats, comparison tables, product specifications, and FAQ sections. Structured data (schema markup) helps AI understand your content’s meaning. JSON-LD for Product, FAQ, Organisation, and HowTo schemas are particularly valuable.
3. Answer the questions your buyers actually ask - Research the prompts people use when asking AI about your category. Tools like CapturAI track real buyer prompts with search volume data. Create content that directly answers these questions — clearly, factually, and comprehensively. The closer your content matches the question format, the more likely AI is to cite it.
4. Build a strong entity identity - AI engines work with entities, not just keywords. Your brand needs a clear, consistent identity across the web — same name, same description, same positioning across your website, social profiles, directory listings, and third-party mentions. Inconsistency confuses AI engines and reduces citation likelihood.
5. Create a llms.txt file - The llms.txt standard is a machine-readable file (similar to robots.txt) that describes your product or brand in a format optimised for LLM crawlers. It tells AI engines who you are, what you do, and how you should be described. Implementing llms.txt is a small technical effort with an outsized impact on how AI engines perceive your brand.
6. Monitor & iterate - AEO isn’t set-and-forget. AI engines update their models, citation patterns shift, competitors publish new content, and your visibility changes. Use an AI visibility tool to track your mention rates, citation sources, and competitor positions across engines — and adjust your strategy based on real data, not assumptions.

Why AEO matters right now?

Three converging forces make AEO critical in 2026:

First, user behaviour has shifted. Research shows that AI platforms are becoming a primary discovery channel for product research, especially in B2B. Buyers ask ChatGPT and Perplexity before they Google. The brands that appear in those AI answers get on the shortlist before traditional search even enters the picture.

Second, AI search traffic converts better. Early data suggests that leads sourced through AI recommendations convert 2-4x better than traditional search traffic. The AI does the pre-qualification - by the time a buyer reaches your site from an AI recommendation, they already trust you.

Third, it’s still early. Most brands have no AI visibility data, no AEO strategy, and no monitoring in place. The window to establish "answer equity" - a strong, durable position in AI responses is open right now. Early movers who build citations and optimise content today will have compounding advantages that latecomers will struggle to overcome.
