The Short Answer
Answer engine optimization (AEO) is the work of getting AI assistants to quote, name and cite your brand when people ask questions. Generative engine optimization (GEO) means nearly the same thing. Both aim to put you inside the answer, not below it.
AEO has two halves. The first is measurement: does AI mention you today? The second is change: improving your content and reputation so it mentions you more.
AEO vs GEO
The industry uses the two terms interchangeably. Where people draw a line, it looks like this.
| AEO | GEO | |
|---|---|---|
| Goal | Get your page quoted as the direct answer | Get your brand named and cited in an answer AI writes |
| Where you appear | A single answer box or spoken answer | A written answer that blends several sources |
| What helps | Clear questions, direct answers, FAQ structured data | Mentions on sources AI trusts, comparisons, complete pages |
Andreessen Horowitz popularized the term GEO in May 2025. Others prefer AEO, because GEO also means geography and geo-targeting. TDC Signal calls the result of both AI visibility.
Why AEO Matters Now
More buyers ask AI for a recommendation instead of scanning a list of links.
Ahrefs found AI Overviews cut clicks on top Google results by 58%.
When the answer appears on the page, fewer people click through. The brands named in that answer get the attention instead.
How AEO Differs From SEO
SEO Wins a Link
Search engine optimization earns a position in a list of results. The reader still chooses where to click.
AEO and GEO Win the Answer
The AI reads sources, picks a few brands and writes the answer. Buyers can decide without clicking a link.
The Two Overlap
Google says optimizing for AI search is still SEO. Crawlable pages and clear content help both.
How to Improve Your AI Visibility
Treat AEO as a loop. Each pass tells you what to change next.
List the Questions Buyers Ask
Write the questions a buyer types before choosing a product like yours, such as "best payroll app for 5 employees".
Measure Your Visibility
Ask each AI engine those questions on a schedule. Record whether you appear, your position, the sentiment and the cited sources.
Study the Answers You Lose
Look at the searches the AI ran and the pages it cited. Note what those pages cover that yours do not.
Close the Gaps on Your Site
Add direct answers, FAQ sections, comparisons and structured data. Let AI crawlers read your pages.
Earn Mentions Where AI Looks
AI cites review sites, forums and roundups. A presence on those sources makes you easier to recommend.
Measure Again
Mark the date each change ships and compare visibility before and after.
