Right now, someone is asking ChatGPT for your business hours. ChatGPT is confidently answering. And there is a good chance the answer is wrong.
This is not a hypothetical. We have scanned hundreds of local businesses through PACO GEO and found that AI models get basic facts wrong about the majority of them. Wrong phone numbers. Wrong addresses. Services listed that the business stopped offering years ago. Hours that were accurate in 2023 but have changed twice since.
The AI industry calls these mistakes "hallucinations." That sounds almost charming. But when a customer calls the wrong number or shows up at your shop on Sunday because ChatGPT said you were open, it is not charming at all. It is lost revenue and a bad first impression you never even knew about.
What Are AI Hallucinations, Exactly?
When an AI model like ChatGPT, Claude, Gemini, or Perplexity states something as fact that is actually wrong, that is a hallucination. The model is not trying to deceive anyone. It is doing what language models do: predicting the most plausible next words based on patterns in its training data.
The problem is that "plausible" and "true" are different things. If the AI has conflicting information about your business from different sources, it picks whichever one fits the pattern best. If it has no information at all, it sometimes invents something that sounds right.
For local businesses, the most common hallucinations fall into predictable categories.
The Five Hallucinations That Cost You Customers
1. Wrong business hours
This is the most common one we see. Your Google Business Profile says you close at 6pm. An old Yelp listing says 8pm. A directory from 2021 says 5pm. The AI picks one and states it as fact. A customer drives across town and finds the door locked.
2. Wrong phone number
You changed your phone number two years ago. The old number is still floating around on directories you forgot about. When a customer asks the AI for your number, they get the old one. The call goes nowhere. They call the next business instead.
3. Services you don't offer
A competitor in your area offers emergency service. You do not. But the AI conflates information from multiple businesses in your category and tells a customer you offer 24/7 emergency calls. The customer calls at 2am. Nobody answers. They leave a one-star review.
4. Wrong location or service area
The AI says you serve a neighborhood or zip code that you actually do not cover. Or it gives your old address from before you moved. Either way, the customer is frustrated and you never know why your leads from that area dried up.
5. Invented reviews or ratings
This one is particularly strange. AI models sometimes fabricate specific review quotes or state a rating that does not match your actual Google or Yelp rating. A customer reads "4.2 stars" from the AI but sees 4.8 on Google and wonders which one to trust.
Why This Happens
AI models are not doing their own research. They are working with whatever data they have access to, which comes from three places: their training data (a snapshot of the internet from months ago), live web search results (for models that browse), and structured data feeds from directories and databases.
The problem for local businesses is that all three sources are often inconsistent. Your website says one thing. Google Business Profile says another. Yelp has outdated information. A random directory you never even created a listing on has scraped your info and gotten it wrong.
When the AI encounters conflicting data, it does not flag the conflict. It picks the version that seems most authoritative or most common. And it states it as fact with zero indication that the information might be wrong.
The silent killer: You will never get a notification when an AI model hallucinates about your business. No customer complaint email. No error alert. The customer just quietly goes to your competitor. The only way to catch it is to actively monitor what AI models are saying about you.
How to Find Hallucinations About Your Business
The manual approach takes about 15 minutes. Open ChatGPT, Claude, Perplexity, and Google Gemini. Ask each one the same set of questions about your business: What are your hours? What is your phone number? What services do you offer? What is your address? What are your reviews like?
Compare every answer to your actual, current information. Write down every discrepancy. You will probably find at least two or three.
The faster approach is to use PACO GEO's free visibility scan. It queries all four major AI models automatically and flags every piece of information that does not match your verified business data. Takes about 60 seconds instead of 15 minutes, and catches things you might miss doing it manually.
How to Fix Them
Finding hallucinations is the easy part. Fixing them requires giving AI models a single, authoritative source of truth about your business. Here is what actually works.
Fix your data at the source
Update your Google Business Profile, Yelp, Bing Places, and Apple Maps listings. Make sure your name, address, phone number, hours, and services are identical everywhere. AI models weigh consistency across sources heavily. If five directories agree and one disagrees, the AI trusts the majority.
Add structured data to your website
Schema.org markup tells AI models your business facts in a machine-readable format. A LocalBusiness schema with your correct hours, phone, address, and services is the strongest signal you can send. It is the difference between the AI guessing and the AI knowing.
Create an AI-optimized profile
PACO GEO builds a dedicated business profile with complete structured data that AI models can parse directly. Think of it as your business card for AI. Every fact is verified, marked up with Schema.org, and submitted directly to search indexes.
Monitor continuously
Fixing hallucinations once is not enough. AI models update their training data, new directories scrape your info incorrectly, and competitors change the landscape. Weekly monitoring catches new hallucinations before they send customers to the wrong place.
What PACO Hallucination Detection Actually Does
PACO GEO includes a hallucination detection engine that runs automatically. It works in three steps.
First, it establishes your ground truth. Your verified business name, address, phone, hours, services, and ratings from your own confirmed data.
Second, it queries ChatGPT, Claude, Perplexity, and Gemini with the exact questions your customers would ask. "What are the hours for [your business]?" "Does [your business] offer [specific service]?" "What is the phone number for [your business]?"
Third, it compares every AI response against your ground truth and flags discrepancies. You get a report showing exactly what each AI model got wrong, so you know where to focus your corrections.
Real example: A dentist in Phoenix had the right phone number on Google but a disconnected number on three old directories. ChatGPT was serving the disconnected number to everyone who asked. After PACO detected and fixed the inconsistency, the correct number started appearing across all four AI models within a week.
The Bottom Line
AI hallucinations about your business are not a future problem. They are happening right now. Every day that an AI model tells a potential customer the wrong information about you, that customer goes somewhere else.
The fix is not complicated. It is just work that most business owners do not know they need to do. Consistent data across every directory. Structured markup on your website. Ongoing monitoring to catch new errors as they appear.
You can do it yourself in a few hours, or you can let PACO GEO handle it automatically. Either way, do not let AI keep lying about your business.
