AEO hub · Updated October 2026

You rank on page one. ChatGPT still names your competitor.

By Joe Robison, founder of Green Flag Digital

The short answer

Answer engine optimization (AEO) is the practice of making your brand the source an AI system cites or names when it answers a question, across Google AI Overviews and AI Mode, ChatGPT, Perplexity, Gemini and Copilot. SEO earns a ranking and a click. AEO earns a mention inside the answer.

The 60-second version

Three jobs. Only one of them happens on your site.

01

SEO gets you ranked

Pages, links and technical health earn positions in Google and the clicks that come with them.

02

AEO gets you named

Answer engines summarize the web and name a few brands. AEO shapes whether yours is one of them, and how it’s described.

03

Other people’s words decide it

Most of the citations you’ll earn won’t point at your website. They’ll point at the places that talk about you.3

Our research

We pulled 5,000 URLs ChatGPT cites. Ranking and citation are decoupled.

The study shows which pages ChatGPT actually names, and why a page-one ranking no longer decides it.1

Key takeaway
A page-one ranking does not decide who ChatGPT names. The pages it cites and the pages that rank are increasingly different sets.

Quick answers

What CMOs ask us first

Is AEO the same as GEO?

In practice, yes. Both mean earning citations and mentions inside AI-generated answers. GEO is the label more buyers search for, 4,400 times a month versus 2,400 for AEO, so you’ll see both here.2

Does AEO replace SEO?

No. SEO earns the ranking and the click. AEO adds the mention inside the answer. Our citation study found the two have come apart, so you need both.1

How do I know if AI tools mention my brand?

Ask the engines the questions your buyers ask, record which brands get named and how, then repeat on a schedule. Our tracking-tools guide compares the trackers that automate this.

Where should a B2B team start?

With the questions buyers ask before they talk to sales. Map them, check who gets named today, then close the gaps on your site and in the publications AI tools trust.
