What Is AEO (Answer Engine Optimization)?

Answer Engine Optimization (AEO) is the practice of getting your brand mentioned and recommended inside the answers that AI engines — ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews — return when people ask them questions. It's the discipline of ranking inside the answer, not just inside the list of links below it.

AEO in plain terms

First, one thing to clear up: the GEO you'll see alongside AEO in this article has nothing to do with geography, GPS, or location tracking. Both are search-marketing terms. AEO stands for Answer Engine Optimization.

Here's the shift it responds to. People used to type a question into Google and pick from ten blue links. Now they ask ChatGPT, Gemini, or Perplexity and get one written answer — often a short list of recommended names. If your brand is in that answer, you're in the running. If it isn't, the buyer may never learn you exist.

AEO is the work of getting into those answers. That means being the kind of source AI engines pull from: clear content, third-party coverage, reviews, and citations the models trust. Do it well and the engine names you when someone asks "what's the best tool for X?"

AEO vs GEO vs SEO

These three terms overlap, and the industry hasn't fully settled on one. Google's own guidance says it's all still SEO. In practice, here's how marketers use each label in 2026.

The honest version: GEO and AEO describe almost the same work. GEO is the label most SEO practitioners use; AEO is the label some tools and review sites (including G2's category name) prefer. SEO is the older, broader discipline both grew out of. If you're doing one well, you're doing most of the others too.

The distinction that matters isn't the acronym. It's the surface. SEO optimizes for a page of links. AEO and GEO optimize for a generated answer that names a handful of brands and moves on. Different surface, different measurement.

Why AEO matters now

Two things changed at once. AI answers went mainstream, and they don't show up in your existing analytics.

When someone asks ChatGPT "which CRM works with Shopify?" and it recommends three tools, that's a buying moment. No impression lands in Google Search Console, because the query never touched Google. You can't see it, so you can't manage it — unless you go looking.

That's the gap AEO addresses. The buyers are already asking. The engines are already answering. The only question is whether your brand is in the answer or a competitor's is.

How AEO actually works

The tactics look a lot like content marketing and PR, aimed at a new reader — the model.

• Publish clear, answer-shaped content. Pages that state a claim directly, back it with specifics, and stay current get pulled into answers more often. Fresh dates help: AI-cited pages skew newer than Google's top organic results.
• Earn third-party coverage. Engines lean on review sites, listicles, and community discussion (G2, Reddit, industry roundups) when they recommend brands. Being present in those sources feeds the answer.
• Cover the questions your buyers ask. Comparative content — "X vs Y," "best tool for [use case]," "alternatives to Z" — matches the commercial prompts people bring to AI engines.
• Track the result. You can't improve what you can't see. AEO only works as a loop when you measure whether the mentions are growing.

Measuring AEO

Three numbers tell you whether AEO is working:

1. Mention rate — how often an engine names your brand for a given prompt. This is the closest thing AEO has to a keyword ranking.
2. Share of answer — when your category comes up, how much of the answer is about you versus everyone else.
3. Sentiment — being named "affordable and reliable" beats being named "limited compared to X." The surrounding words matter.

You track these by running real buyer questions against the major engines on a schedule and recording what comes back. That's what a GEO tracker does, and it's how AEO stops being guesswork.

Geotally measures all three across all six major engines — ChatGPT, Claude, Gemini, Perplexity, Copilot, and Google AI Overviews — on every plan, from $19/mo, with a free tier to start. New to the category? Read what GEO is or see how we track Google AI Overviews.
