AI Search (ChatGPT, Claude, Gemini) gives completely different answers depending on your city. Here is why this matters for local Small Businesses.
For the last year, everyone tracking AI visibility has been asking: "Does ChatGPT mention my business?"
That is the wrong question.
We ran thousands of identical prompts across ChatGPT, Gemini, Perplexity, and Claude from different geographic contexts. The results confirmed that AI answers are not the same in every city. Across the prompts we tested, the top-recommended product or service changed in 41% of major U.S. metros for the exact same query.
For categories like home services, fitness, and local retail, the variance was even higher.
If you are running a small business, this is a critical shift. When a user asks an AI assistant for a recommendation, the model does not pull from a single global ranking. It blends:
- Localized retrieval (Google and Bing SERPs return different local packs by region)
- Regional citation sources (local publications, local reviews, city-specific forums)
- Inferred location signals (user IP, prompt context like "near me")
The Google Business Profile (GBP) Angle
This means your Google Business Profile and local citations feed directly into the AI's localized logic. A business that dominates the AI response in one ZIP code can be completely invisible just a few miles away. We call this "regional drift."
If your small business relies on local foot traffic or service areas, you cannot rely on a generic, national AI visibility score. You are flying blind. The AI is heavily weighing where you are, using your GBP data and local directory mentions to filter you in or out of the response.
We just launched a tool (Sanbi AI) to map this out geographically, allowing brands to see their AI visibility as a literal map instead of a single score. But regardless of the tools you use, the takeaway for small businesses is clear: localized content, geo-targeted reviews, and consistent GBP signals are what dictate if an AI recommends you to a local buyer.
Has anyone else noticed their business showing up inconsistently in AI responses depending on where the prompt is run?
