Summary
- AI tools answer from training data and live web searches.
- ChatGPT's live answers lean heavily on Bing's results.
- Google Business Profile, directories and reviews drive most local citations.
- Consistent details everywhere are the safest strategy.
The Short Answer
ChatGPT gets its information about businesses from what it learned during training plus live web searches, which lean heavily on Bing results, directories, review sites and business websites. For local questions, your Google Business Profile, listings and reviews often matter as much as your own site.
You can't control which sources an AI tool picks, but you can make sure every source says the same, accurate thing about you.
Training Data and Live Search
AI tools answer from two places: what they learned when they were built, and what they find when they search the web for your question.
Training data is old and you can't change it. Live search is where you have influence, because the tool looks at pages and listings that exist today. That's why the actions below focus on what's online now.
What the Studies Show
Several 2026 studies looked at which sources AI tools cite, and five findings matter for a service business.
| Finding | What it means for you | Your action |
|---|---|---|
| Google Business Profile is behind about 42% of local AI citations; directories 28%; business websites 17% | Your profile and listings matter as much as your site | Complete your profile; claim key directories |
| About 87% of ChatGPT's web citations match Bing's top results | ChatGPT's live answers lean on Bing | Submit your site to Bing Webmaster Tools; claim Bing Places |
| Review sites like Yelp are among the most cited sources for local questions | What customers write about you is reused by AI | Ask for reviews; reply to every one |
| Reddit appears in about 46.7% of Perplexity's top citations in one benchmark | Community discussions shape some AI answers | Answer questions honestly where your customers ask them |
| Inconsistent details across platforms reduce AI tools' confidence | Two phone numbers can cost you a mention | Make your details identical everywhere |
Where Each AI Tool Tends to Look
Each AI tool has its own habits, but they overlap more than they differ.
| AI tool | Tends to rely on | What helps you most |
|---|---|---|
| ChatGPT | Bing's index for live answers, plus well-known directories and review sites | Bing listing, Yelp, consistent details |
| Perplexity | Recent, clearly written pages and community discussions | Fresh content with dates, honest forum answers |
| Google AI Overviews | Google's own index and popular community and video sites | Strong Google rankings, Google Business Profile |
| Gemini | Google's index and Google services | Your Google Business Profile and website |
