Key takeaways
- AEO is the work of getting your company named, cited, and described correctly in AI answers.
- AEO, GEO, and AI SEO describe the same goal. The names are still settling.
- Google says AI Overviews need no special files or schema, so AEO starts with SEO basics.
- Mentions on other sites correlate with AI visibility far more than backlinks do.
- AI answers vary between runs, so measure percentages across repeated runs, not single answers.

What answer engine optimization means
Answer engine optimization (AEO) is the work of getting your company named, cited, and described correctly in AI-generated answers, such as ChatGPT, Claude, Perplexity, Google AI Overviews, and AI Mode. It applies the discipline of SEO to answers instead of rankings.
In search, the unit of success is a position on a results page. In an answer engine, there is no page of ten links to rank on. There is one written answer, and your company is either in it or not. If it is in it, the answer may describe you correctly or get your prices, rates, or features wrong.
So AEO asks three questions about the questions your buyers type:
- Does the answer mention you?
- Does it cite one of your pages as a source?
- Is what it says about you true?
How answer engines choose what to say
Most answer engines now search the web before they answer. The model rewrites the question into several searches, reads the pages that come back, and writes an answer from them. Google describes this for AI Overviews and AI Mode as a "query fan-out" technique, "issuing multiple related searches across subtopics and data sources."1
That gives you two ways into an answer:
- A citation, when the engine links one of your pages as a source for what it said
- A mention, when the engine names your company, often because other sites it read named you
The two don't always travel together. An engine can cite your guide without recommending you, or recommend you while citing a review site, a directory, or a forum thread instead of your own pages. Good AEO work tracks both.
AEO, GEO, and AI SEO are mostly the same work
The names are still settling. Answer engine optimization, generative engine optimization (GEO), AI SEO, and LLM optimization all describe the same goal: being part of AI answers.
GEO comes from a 2023 research paper by Princeton and Georgia Tech researchers, published at KDD 2024. The authors tested ways of rewriting web content and reported that the best methods could raise a source's visibility in generative engine responses "by up to 40%."2 That number came from a lab benchmark, not live ChatGPT traffic, but it showed that how a page is written changes whether an engine uses it.
In practice, agencies and tools use the terms interchangeably. We use AEO and GEO together, and you can read our comparison of AEO, SEO, and GEO for where they differ.
What changed in Google search
Google's AI Overviews put an answer above the links, and that changes who gets the click.
- In a Pew Research Center study of 68,879 searches by 900 US adults in March 2025, people clicked a traditional result on 8% of visits when an AI summary appeared, compared with 15% when none did. They clicked a link inside the summary on 1% of visits.3
- Ahrefs found that an AI Overview correlated with a 58% lower average click-through rate for the page in position one, based on 300,000 keywords in December 2025.4
- Seer Interactive found that brands cited in an AI Overview earned about 120% more organic clicks per impression than brands that were not cited on the same kind of results page, from January 2025 to February 2026.5
Clicks are falling for everyone, and the companies that the answer cites keep more of what is left. That is the commercial case for AEO.
Google's own guidance is that "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary."1 The pages that appear are pages that can be crawled, indexed, and shown with a snippet. That is why AEO starts with SEO basics, not with special files or markup.
What AEO work involves
AEO is not one tactic. It is five kinds of work, usually in this order:
- Access. Make sure AI crawlers such as GPTBot, ClaudeBot, and PerplexityBot can reach your pages, and that the content is in the HTML rather than loaded by JavaScript. Our AI crawler checker tests this.
- Facts. Put your prices, rates, fees, features, and eligibility rules on crawlable pages in plain sentences, and keep them the same everywhere they appear.
- Answer-shaped pages. Write pages that answer the questions buyers ask, with a direct answer near the top, specific numbers, and named sources an engine can quote.
- Off-site mentions. Get named on the review sites, comparison articles, directories, and forums that engines read. In an Ahrefs study of 75,000 brands, brand web mentions correlated with AI Overview visibility at 0.664, compared with 0.218 for backlinks.6
- Corrections. Find what engines get wrong about you and fix the sources they learned it from.
The first three happen on your own site. The fourth is closer to PR than to SEO, and it is usually where the biggest gains are.
How to measure AEO
AI answers change from run to run. In a SparkToro study of 2,961 queries run by 600 volunteers in late 2025, there was less than a 1 in 100 chance that ChatGPT or Google's AI would give the same list of brands in any two responses.7 Ranking position inside an answer is close to meaningless. Percentages across many runs are not.
| Measure | What it counts | How to read it |
|---|---|---|
| Mention rate | Share of answers that name you | Run each question at least three times and report a range |
| Citation rate | Share of answers that link one of your pages | Tells you which of your pages engines trust |
| Share of voice | Your mentions compared with competitors' mentions | Only meaningful across the same question set |
| Accuracy | Share of statements about you that are correct | The measure regulated companies care about most |
Our free AI visibility checker runs the first three for your category, and the AI accuracy checker covers the fourth.
What AEO looks like in finance
In financial services, the problem is less often "AI doesn't mention us" and more often "AI says something wrong about us." Rates, fees, and limits change, and engines repeat whatever they read last.
When Which? tested five AI tools on 15 personal finance questions in July 2026, aggregate scores ranged from 60% for ChatGPT and Perplexity to 68% for Gemini. The testers found made-up figures and outdated tax rates.8 That study covered UK consumer questions, but the failure modes carry over.
Which mortgage lender near Albany has the lowest 30-year fixed rate?
Several lenders in the Albany area offer 30-year fixed mortgages. Example Home Loans lists rates starting around 6.1%, though rates depend on credit, down payment, and points. Check current rates on each lender’s site before applying.
For a regulated company, AEO adds a review step: every fact you publish for engines to read is also a fact your compliance team has to approve. We build that step into how we work.

Questions people ask
Is AEO the same as SEO?
No, but it is built on it. SEO earns rankings and clicks. AEO earns mentions and citations inside AI answers. Most AI answers are written from pages that already rank, so a site with weak SEO rarely does well in AEO.
Is AEO different from GEO?
No, not in practice. Generative engine optimization comes from a 2023 research paper, and answer engine optimization comes from the earlier work on featured snippets and voice answers. Both describe getting your company into AI-generated answers.
Do I need special markup or an llms.txt file to appear in AI Overviews?
No, Google says there are no additional requirements and no special schema or AI text files needed for AI Overviews or AI Mode. Structured data still helps engines read facts such as prices correctly.
How long does AEO take to show results?
Fixes to crawler access and on-site facts can show up within weeks, once engines re-read the pages. Off-site mentions usually take two to six months, because they depend on other sites publishing.
Can a small firm do AEO without a paid tool?
Yes, for a start. Twenty buyer questions asked three times each in two or three engines will show where you stand. Tools help once you need to track hundreds of questions over time.
How do I know if ChatGPT mentions my company?
Ask it the questions your buyers ask, several times each, and count how often you are named. Our free AI visibility checker does this across ChatGPT and Claude for your category.
