How AI Assistants Choose Which Brands to Recommend
The working model your team needs before it sells AI search visibility to anyone.
Two ways an answer gets made
When a buyer asks ChatGPT, Gemini, Claude or Perplexity which accounting software to use, the assistant answers in one of two ways. It either answers from what its model learned in training, or it searches the web first and writes an answer from the pages it found. Many consumer apps now do the second for questions about products and services. That difference matters for your clients. Training knowledge changes slowly and reflects how often and how consistently a brand was described across the web. Search-backed answers change weekly and reflect which pages rank and are easy to quote right now.
For an agency this means AI search work is not a new magic channel. It sits on top of two things you already understand: a brand's footprint across the web, and pages that answer real questions clearly.
What Google says about its own AI features
Google's guidance for site owners on AI Overviews and AI Mode is direct. It says there are no additional requirements to appear in those features, and no special schema or AI text file is needed. A page must be indexed and eligible to show with a snippet to be used as a supporting link, and Google notes that serving is never guaranteed. It also explains that these features can run several related searches behind one question, which it calls query fan-out, to find a wider set of supporting pages.
Use this with clients. It is the most useful sentence you can share when someone asks whether they need a special AI file to be found: foundational SEO, crawlable text and helpful pages still decide most of the outcome.
The signals that move recommendations
Across engines, the brands that get named tend to have a clear category position, consistent descriptions on their own site and on third-party sites, comparison and review coverage, and pages that answer the question the buyer actually typed. Missing any of these shows up as a predictable gap: the assistant names three competitors and leaves your client out, or names them with an outdated description.
- Category clarity: one sentence that says what the brand is and for whom, repeated consistently.
- Third-party coverage: directories, review sites, comparisons and media that assistants cite.
- Answer pages: content that states the answer first, then the detail.
- Freshness: pricing, features and locations kept current.
- AI answers come from training knowledge or a live web search, and the two behave differently.
- Google says no special markup or AI file is required for its AI features.
- Brands get named when their category position and third-party coverage are clear and consistent.
Pick one client. Ask three AI assistants the same buyer question about their category, with web search on where you can. Note which brands are named, what each assistant says about your client, and which sites are cited.
