What is AEO, and what Google actually says about optimizing for AI answers

AEO, short for answer engine optimization, is the name for the work of getting a brand's content into the answers that AI systems assemble from multiple web pages. Google groups it with another acronym, GEO, and refers to the topic as AEO/GEO.

Where the idea comes from

A study published on arXiv describes generative engines: search engines that use language models to gather information from multiple sources and summarize it into a single answer. According to the authors, this shift creates a problem for content creators, who have little or no control over when and how their material shows up in those answers.

To address that, the study proposes GEO, generative engine optimization, a method for improving content visibility in those answers. In tests run on GEO-bench, a broad set of questions spanning different fields, visibility rose by up to 40%. The study also shows that the impact of each strategy varies by field, which calls for tailored adjustments depending on the subject matter.

How it works on Google

In its Google Search Central documentation, Google explains that AI Overviews and AI Mode show relevant links alongside the answer. AI Mode is designed for queries that call for exploration, reasoning or complex comparisons.

Both features can break a question down into several related searches across subtopics and data sources to build the answer. As a result, they surface a wider and more diverse set of links than a classic search. Because they may use different models and techniques, the answers and links vary between the two. AI Overviews only appears when Google's systems determine it adds value beyond classic search results, which is why it often doesn't trigger at all.

What Google recommends

According to Google, AI Overviews and AI Mode don't require any specific optimization. To appear as a supporting link, a page needs to be indexed and eligible to be shown in Search with a snippet, with no additional technical requirements. The SEO fundamentals still apply:

• allow crawling in robots.txt and in any CDN or hosting setup;
• make content easy to find through internal links;
• keep important content available as text;
• support the text with high-quality images and videos where it makes sense;
• make sure structured data matches the visible text;
• keep Merchant Center and your Google Business Profile up to date.

In a guide announced on the Google Search Central blog, written by John Mueller of Google Search, the company stresses the importance of valuable, unique, non-commodity content, offers tips on local, shopping, image and video content, clears up common misconceptions about AEO/GEO and provides initial guidance on AI agents.

Traffic from AI Overviews and AI Mode is included in the Search Console Performance report, under the Web search type. Google also says that clicks from results pages with AI Overviews are higher quality, with visitors spending more time on the site. To limit what appears, you can use robots.txt for Googlebot and the nosnippet, data-nosnippet, max-snippet and noindex controls.

For brand teams, Google's message is clear: showing up in AI answers in Search depends on the same SEO fundamentals as always: an indexed page, helpful and unique content, accurate data and monitoring in Search Console.
