What is AEO (answer engine optimization)?

Answer engine optimization (AEO) is the work of getting your company named and cited when people ask AI tools like ChatGPT, Perplexity or Google AI Overviews a question. It builds on SEO: AI engines search the web, read pages and quote sources, so being findable and quotable is the core of it.

Your buyers already ask these tools what to buy. 51% of B2B software buyers start research in an AI chatbot more often than Google. Gartner found that 9% of buyers discover software with GenAI tools vs 8% via search engines. If the answer names three rivals and not you, you may never hear about that lost deal.

This guide shows how an AI answer gets built and what AEO is not. Then it gives a short test for whether your SaaS needs it, one real answer from our platform, and a plan for your first 30 days.

How does an AI answer get built?

In three steps: the engine searches, reads, then writes one answer with sources. If your pages are not found or not readable, you cannot be quoted.

1. Search. The engine turns the question into its own web searches. From our platform: when asked "What's the best AEO agency for a B2B SaaS company?", one engine searched for "best AEO agency B2B SaaS 2026 answer engine optimization" and similar phrases.

2. Read. The engine's bots fetch the pages it found. Each AI company runs named bots, and you control them in robots.txt:

3. Write and cite. The engine writes one answer and links some of the sources it read. OpenAI explains how this works in its help article on searching the web with ChatGPT.

Think of the answer as the new shelf. Buyers used to scan ten links. Now they read one answer, and only a few companies make it onto that shelf.

What AEO is not

AEO is not a trick. It is not a file, a tag or a batch of fake posts.

• Not a schema trick. Google says no extra requirements or special optimisations are needed to appear in AI Overviews and AI Mode. Valid schema is good hygiene. It is not what gets you named.
• Not llms.txt. llms.txt is a proposal by Jeremy Howard (2024). Adding one is cheap, but no one has shown it gets you cited.
• Not mass AI content. Google warns against scaled content abuse; focus on helpful, people-first content.
• Not fake reviews or hidden posts. Reviews must come from real clients. Community posts must say who wrote them.
• Not a separate world from SEO. Engines search the web, so the SEO base still matters.

Does your SaaS need AEO?

Probably, if your buyers research before they talk to sales. Answer these five questions about your company.

The more yeses, the sooner AEO pays its way. If you answered no to the first two, put your money into sales and product first.

To check question 5, ask your category questions in ChatGPT and Perplexity. Ask each one a few times, since answers change from one ask to the next. Note who is named and which sources are linked.

What does a real AI answer look like?

Here is one buyer question from our platform, asked in September 2026: "What's the best AEO agency for a B2B SaaS company?" We asked it on ChatGPT and on Perplexity, with web search on (method).

ChatGPT. It named five agencies: XEO.works, Takeoff Agency, Trivero Marketing, LLM Listed and Angelfish Marketing. ChatGPT cited only Clutch and G2 profile pages, and it did the same each time we asked again.

Perplexity. It named Omniscient Digital first, then First Page Sage, RevenueZen, NoGood, Quoleady and Embarque. Most of the sources it read were "best AEO agencies" lists, many of them on agency sites. The rest were LinkedIn posts, a media article and a guide. The answer itself warned that many agency rankings are written by the agencies themselves.

What the two answers had in common. Nothing. No agency appeared in both answers. Perplexity named Omniscient Digital each time we asked, and ChatGPT never did (our platform).

The lesson for any SaaS company: each engine built its answer from a different shelf. ChatGPT cited directory profiles. Perplexity's sources were mostly "best of" lists. To be named on both, you need to be on both shelves. We go deeper in how ChatGPT decides which companies to recommend.

What should you do in your first 30 days?

Check where you stand, open the door to AI bots, fix your key pages, and start earning mentions. This checklist assumes a small team.

Do not expect a big change in 30 days. The first month sets your baseline and fixes what blocks you.

How do you measure AEO?

Count how often AI answers name you for your buyer questions, then follow those buyers into your pipeline. Report each number with the questions behind it.

• Share of answers. For each question and engine: answers naming you, out of the times you asked. "Named in X of Y asks" is useful. A single score with nothing behind it is not.
• Sources. Which pages each engine used when it named you, or named a rival instead.
• AI visits. Visits from ChatGPT, Perplexity and others, as their own channel in GA4.
• Pipeline. Leads and deals where the buyer says they used an AI tool.

Answers change from one ask to the next, so one check proves little. Track the same questions on a fixed schedule.

How are AEO, SEO and GEO different?

They overlap far more than they differ. SEO is about ranking pages in search engines. AEO is about being named and cited in AI answers. GEO (generative engine optimization) is a near-synonym for AEO, used more by some teams.

The term GEO comes from a research paper. GEO: Generative Engine Optimization (Aggarwal et al.) reports visibility gains of up to 40% in generative engine responses. That was a lab study, not a live market test.
