Answer engine optimization: be the source AI cites
Answer engines don't rank pages, they pick sources. On a narrow question that source is very often a forum thread, because no brand ever wrote about it. FindMention watches 7,566 live forums and emails you when your subject comes up, so you can be the answer that gets quoted.
What is AEO (answer engine optimization)?
AEO, answer engine optimization, is the work of becoming one of the sources an AI answer is built from. Not ranking first. Being quoted.
A search engine like Google lists addresses and lets you choose. An AI writes one answer and names three to five sources. A page that is not among them gets nothing, even if it would have ranked first.
The question changes in kind. Your rank in a list counts for less than your presence among the sources the model puts together.
And it finds you where your subject is already being discussed.
Where answer engines find their answers: 7,566 live forums
We add forums every day. If one is missing in your market, write to us and we will add it.
- Forums tracked
- over 7,000 across 13 languages
- Public profiles
- 3,360 a forum earns one at 100 discussions
- Discussions read
- over 3,500,000 and more on every pass
- Sources polled
- over 36,000 feeds, sections and pages
Most of these forums appear in no directory. We find them by the signature of the software they run on: a viewtopic.php in the address, a “powered by phpBB” in the footer. That is how a forum with twelve members enters the registry, and a small forum is where a problem gets written out in full.

Why forums get cited on narrow questions
Ask an answer engine something broad and it quotes the same large sites as everyone else. Ask it something narrow and the list changes completely.
That second list is the one worth understanding. Answer engines do not draw from the same pool as a page of search results. They favour text where a real person works through a real case, and they reach much further down the tail than a ranking ever did.
On a narrow question the commercial web has written nothing. No manufacturer publishes about an engine shudder on a nine-year-old hybrid. The model does not have fewer sources, it has other ones, and it lands on forums.
This is structural. It will not change with the next algorithm update, because the reason is simply that nobody else wrote the answer.
The places cited on your subject can be counted, and almost nobody watches them. One example, measured on 1 October 2026. On “heat pump short cycling in cold weather”, diychatroom.com is the first result on Google, ahead of the manufacturers and the installers. Type the query and you will see what we see.
Measure your visibility, then find where to act
A whole category of tools now checks whether ChatGPT or Perplexity mentions your brand. Those tools measure your presence; FindMention tells you where to act to change it.
They answer with a percentage of mentions, which tells you where you stand.
An answer is built out of sources. To appear in it you have to be inside one of them, and on a narrow question that source is a thread where someone asked. So it is a specific place and a specific moment.
The two go together. The percentage shows whether things are moving; the threads show you where to start.
How FindMention works
- Enter a keyword
Your brand, a competitor's, a product, a question your customers ask. A word only counts when it appears whole: “gas” does not trigger on “magazine”.
- Narrow it, or don't
A keyword can be limited to a country or a language, and you can rule out the words and the sites that make noise. By default we filter nothing.
- Get an alert as soon as a thread matches
You only get an email when a thread matches your search. It carries the title, the forum, the section, the keyword that was found and a direct link to the conversation. The same thread is never sent twice.
About an hour in the median between the post and your email. Speed changes everything. While the thread is still open, your answer shapes what the next readers take away. Three weeks later the opinion is settled.
How to get cited by ChatGPT, Perplexity and Gemini
Nobody controls what a model quotes. You control what there is to quote, and five habits separate a thread that gets used from one that does not.
- Answer the whole question
A model looks for a passage it can lift as it stands. Half an answer, or an answer that points somewhere else, gives it nothing to work with.
- Be specific and checkable
Model numbers, versions, prices, dates. A concrete detail is what makes one passage worth quoting instead of the ten vague ones around it.
- Get there early
The first useful reply in a thread is the one that gets read, quoted and built on. The fifteenth is buried, however good it is.
- Say the same thing everywhere
Models cross their sources. A claim that appears on your site, in a forum answer and in a comparison holds better than the same claim in one place.
- Say who you are
Declare yourself and answer honestly. Most forums welcome it, and a named expert is more quotable than an anonymous account, not less.
What remains is finding the thread while it is still open. FindMention emails you as soon as your subject comes up, so you arrive while the question is still waiting for an answer. And the link you leave there holds, because it answers something.
Frequently asked questions
What is the difference between SEO and answer engine optimization?
Less than the marketing suggests, but not nothing. Both reward clear pages, real expertise and being cited elsewhere. The difference is the prize: SEO wants a rank in a list, AEO wants to be one of the three sources an answer is built from. Ten good positions are worth less than one quoted paragraph.
How do I know if ChatGPT cites my brand?
Today there is no official way. No answer engine publishes what it quoted, and none offers a report. The tools that sell this run prompts and count what comes back, which is a sample rather than a measurement. The honest method is the same one: ask the questions your customers ask, in several engines, and write down what you see.
Do forum posts really get cited by AI answers?
On broad questions, rarely. On narrow ones, constantly. Ask about a specific fault on a specific model and the sources named are threads where an owner described it. That is not a quirk of the model, it is what the model has: nobody else wrote about it.
Can you pay to be cited by an AI?
No, and that is the interesting part. There is no ad slot inside a generated answer today. What gets you in is being the source that answers the question best, which is slow, and which nobody can outbid you for.
