Run the same buyer question through Perplexity, ChatGPT and Claude on the same afternoon and you get three answers that broadly agree and cite almost nothing in common. One gives you a numbered source list. One references two links inside the prose. One gives you a confident paragraph and no attribution at all.
Same question, same open web, three different reading habits. Which is annoying if you were hoping for one checklist, and useful if you were hoping to understand what actually earns a citation.
A citation and a mention are different prizes
Being named in the body of an answer and being listed as a source are separate outcomes with separate causes.
A mention comes from the model having a stable association between your brand and the topic. A citation comes from a specific page of yours being retrieved and used while the answer was being written. You can have either without the other, and plenty of brands get discussed constantly without a single link back.

Both are worth having. The citation is the one you can influence faster, because it depends on a page that exists right now rather than on years of accumulated association.
Each system reaches for sources differently
Treat what follows as observed behaviour rather than documented mechanics, because none of these companies publish the details and all of them change.
Perplexity behaves like a search product wearing an answer interface. It retrieves aggressively, lists what it used, and rewards pages that answer a question directly and near the top. If your page buries the answer under a definitions section, you tend to watch a thinner competitor page get cited instead.
ChatGPT is more selective about when it goes and looks. Plenty of answers come out of what the model already carries, with no retrieval at all, and those answers reflect an older picture of your category. When it does retrieve, it tends to pull fewer sources and lean harder on each one.
Claude is generally conservative with attribution and careful about claims it cannot support. Content that hedges appropriately, defines its terms and avoids overstatement seems to sit more comfortably inside its answers than content written in campaign language.
The overlap across all three is larger than the differences. Clear pages, answered questions, consistent descriptions. The differences mostly tell you where to expect your first wins.
The unit that gets cited is a paragraph
Not a page. A page is what the crawler collects. A paragraph is what ends up inside the response.
So the test is straightforward and slightly humbling. Take any section of your best content, paste it into an empty document, and read it as though you arrived cold. Does it answer something on its own? Does it depend on the two paragraphs above it for the subject of its first sentence? Would you understand what product category is being discussed?
Most editorially strong content fails that test, because good writing accumulates. The fix is not to write badly. It is to give each section a first sentence that states its own subject, and to let the section end when the question is answered rather than when the rhythm feels finished.
Coverage in places you do not own
You can perfect your own pages and still watch answers assemble themselves entirely out of other people's writing.
The mix has moved, and how the sources AI trusts are changing is now a more useful question for most teams than which of their own pages ranks, especially when entrepreneurs build their brand and marketing strategy across independent sources. Community threads, documentation, independent comparison posts, review platforms, industry newsletters. None of them take briefs from you.
What you can do is narrower than a content plan and more effective than one:
- Keep your documentation current and public, since it is often the most retrievable thing you own
- Make sure your own comparison pages are fair enough to be worth quoting, including the parts where you lose
- Give the people who write roundups a clear, short, current description they can copy without rewriting
- Answer questions in public where your buyers already ask them, under your own name, without a pitch attached
Questions phrased the way buyers phrase them
Content built around search terms and content built around questions look similar on the surface and behave very differently once an answer engine is involved.
A term is compressed. A question carries the constraint, the situation and the thing the person is actually worried about. Work on answering buyer questions in AI search tends to start by collecting those questions verbatim from sales calls and support tickets rather than from a tool, because nobody has ever typed a keyword at an assistant.
Then you write the answer where the question can be seen. Same page as the question, near the top, in the buyer's vocabulary rather than your category deck's.
Checking rather than assuming
Build a set of thirty prompts, run them across all three systems, and record what came back. Which sources were used, whether you appeared, how you were described when you did.
Repeat it monthly. A single run is close to meaningless, since these systems reword themselves week to week. What emerges over a few rounds is a short list of prompts where you are consistently absent for a reason you can name.
That list is a better content brief than anything a keyword tool will give you, mostly because it is a list of specific missing sentences rather than a list of topics.
