How does ChatGPT decide which products and brands to recommend?
When you ask ChatGPT for a product recommendation, it doesn't "see" the whole internet and pick a winner. It pulls from a mix of what it learned during training and what it can fetch live from the web, then it favors brands that are described clearly, mentioned often across trusted sources, and easy to summarize in a sentence. In plain terms: ChatGPT recommends the products it can confidently explain. If an AI assistant can't quickly understand what you sell, who it's for, and why people trust it, it leaves you out.
A recent study from the agency Precis looked closely at how ChatGPT "shops" — how it sources, evaluates, and surfaces brands when people ask for buying suggestions. The findings line up with what we see every day inside SimpleAIO audits. Below we translate the research into a plain-English checklist any small-business owner can act on.
Where does ChatGPT get its shopping information?
ChatGPT draws on two things: its training data (a snapshot of the web it learned from) and live web results it retrieves when answering. For shopping questions, it leans heavily on third-party sources — review sites, "best of" roundups, comparison articles, forums like Reddit, and editorial coverage — not just your own website.
This matters because what others say about you often counts more than what you say about yourself. A brand that's mentioned consistently across independent sources is far more likely to be recommended than a brand that only appears on its own homepage.
What to do about it: Get listed and reviewed in the places that cover your category. Aim for mentions on reputable directories, local guides, and roundup articles. Encourage genuine customer reviews on the platforms your buyers actually read.
What signals make a brand more likely to be recommended?
The study points to a recurring pattern. ChatGPT favors brands that are:
- Clearly described. Your product, category, price range, and ideal customer are stated in plain words.
- Frequently mentioned. Your name shows up across multiple independent sources, not just one.
- Consistently described. The same facts (what you do, where you operate, who you serve) appear the same way everywhere.
- Easy to quote. Your site contains short, factual sentences an AI can lift word-for-word.
- Trusted. Reviews, ratings, and credible coverage back up your claims.
Why does ChatGPT leave some businesses out entirely?
Most exclusions aren't a penalty — they're confusion. If an assistant can't determine what you sell or who you're for, it won't risk recommending you. Common reasons a business gets skipped:
- The website explains feelings ("reimagine your mornings") instead of facts ("we sell organic, fair-trade coffee beans shipped within the US").
- Key details — price, location, what's included, who it's for — live only in images or PDFs the AI can't read.
- The brand has almost no presence outside its own website, so there's nothing to corroborate.
- Information conflicts across sources (one says you serve restaurants, another says home cooks), so the AI hedges and picks a clearer competitor.
What's the plain-English checklist to get included in AI shopping answers?
Here's the checklist we use when auditing a site for AI visibility. Work through it in order.
1. State the basics in plain text
Somewhere obvious, answer: What do you sell? Who is it for? What does it cost? Where do you serve? Put it in real sentences, not just a hero image or video.2. Write sentences an AI can quote
Use short, factual lines like: "SimpleAIO is an AI visibility audit tool for small businesses and marketing agencies." That's a sentence an assistant can repeat verbatim. Vague taglines can't be quoted.3. Answer the real questions buyers ask
Use question-style headings that match how people talk to AI: "How much does it cost?", "Is it good for [type of customer]?", "What's included?" Then answer each one directly underneath.4. Build mentions beyond your own site
Get into category roundups, local directories, and review platforms. The goal is for your brand to appear — described consistently — in several trustworthy places an AI might check.5. Keep your facts consistent everywhere
Your business name, location, services, and key claims should match across your website, Google Business Profile, directories, and social profiles. Conflicting information makes AI hesitate.6. Earn and keep real reviews
Genuine reviews and ratings are trust signals. They give an assistant a reason to recommend you over an unproven competitor.7. Make sure the AI can actually read your page
Text hidden inside images, PDFs, or scripts often goes unread. If a fact matters, put it in plain, selectable text.How is this different from regular SEO?
Traditional SEO aims to win a click on a results page. AEO — answer-engine optimization — aims to get named in the answer itself, often with no click at all. The overlap is real (both reward clear content and trusted mentions), but AEO puts extra weight on three things: facts written in quotable plain text, consistency across sources, and third-party validation. You're no longer optimizing only for a search engine — you're making yourself easy for an AI to understand and confidently repeat.
How do you know if ChatGPT would recommend you today?
You can spot-check by asking the assistants yourself: "What are the best [your category] for [your customer]?" and see whether you appear and how you're described. If you're missing — or described inaccurately — that's your to-do list.
For a faster, structured answer, SimpleAIO runs an AI visibility audit that scores how likely you are to be recommended across ChatGPT, Perplexity, Google AI Overviews, Claude, and Copilot, then returns plain-English fixes tied to the checklist above. The fixes are the same boring-but-powerful basics the research keeps confirming: say what you do clearly, say it consistently, and make sure trusted sources say it too.
