Someone needs a plumber. Five years ago, they opened Google and typed "plumber near me." Today, a growing number of people open ChatGPT and type "I have a leaky faucet in my kitchen, who should I call?" The results they get back are completely different, and most business owners have no idea why.
This is a side-by-side breakdown of how ChatGPT and Google actually work for local business discovery. Not theory. Not predictions. What happens right now when a customer searches for your type of business on each platform.
The Fundamental Difference
Google gives you a list of options. ChatGPT gives you an answer.
When you search Google for "best dentist in Austin," you get a map pack with 3 businesses, then a list of 10 blue links, then some ads. Google shows you options and lets you choose. You click through, read reviews, compare websites, and make a decision.
When you ask ChatGPT "who is the best dentist in Austin," you get 3-5 specific recommendations with explanations for why each one is worth considering. ChatGPT has already done the comparison for you. It tells you which dentist is best for anxious patients, which one has the best cosmetic work, and which one is most affordable. The user reads the answer and picks one.
This changes everything about how businesses need to present themselves online.
Where Each Platform Gets Its Data
| Data Source | ChatGPT | |
|---|---|---|
| Business listings | Google Business Profile | Foursquare, Bing Places |
| Web search | Google's own index | Bing search results |
| Reviews | Google Reviews (primary) | Yelp, Foursquare, web mentions |
| Maps/location | Google Maps | Bing Maps, Foursquare coordinates |
| Structured data | Schema.org markup | Schema.org markup + training data |
| Training knowledge | N/A (live index) | Pre-trained on web data through 2025 |
This is the critical point most business owners miss. ChatGPT does not use Google data. A business that dominates Google can be completely invisible to ChatGPT if it has no Foursquare presence, no Bing Places listing, and weak third-party reviews.
Estimated share of ChatGPT's local business data that comes from Foursquare's Places API. Most business owners have never heard of Foursquare in 2026, let alone claimed their listing.
How Results Look Different
Google: "plumber near me"
You get a map showing 3 nearby plumbers with star ratings, review counts, and distance. Below that, you get organic results linking to Yelp, HomeAdvisor, Angi, and individual plumber websites. Google prioritizes proximity heavily. The closest plumbers show up first, even if they have worse reviews.
ChatGPT: "I need a good plumber in Hermosa Beach"
You get a conversational answer naming 2-4 specific plumbers with context. ChatGPT might say: "South Bay Plumbing is well-reviewed for residential work, especially older homes. Beach Cities Plumbing handles emergencies 24/7 and is known for fast response times." It reads more like a recommendation from a knowledgeable friend than a search results page.
The key differences in the results:
- Number of results: Google shows 10+. ChatGPT shows 3-5.
- Context: Google shows star ratings. ChatGPT explains what each business is known for.
- Proximity weight: Google heavily favors proximity. ChatGPT favors reputation and specialization.
- Ads: Google shows ads above organic results. ChatGPT does not show ads (yet).
- Click-through: Google sends you to websites. ChatGPT often gives you enough info to call directly.
What ChatGPT Gets Right That Google Does Not
Complex queries. Ask Google "dentist good with nervous patients who accepts Delta Dental near downtown Portland." You get generic results because Google struggles with multi-factor queries. Ask ChatGPT the same question and it actually tries to match all three criteria. AI search handles nuance better than keyword matching.
Honest comparisons. Google's top results are paid ads and SEO-optimized pages. ChatGPT's recommendations are based on aggregated reputation data. Neither is perfect, but ChatGPT is less influenced by who spent the most on advertising.
Conversational follow-up. "That plumber you recommended, do they work on weekends?" You can refine your search naturally. Google requires a new query.
What Google Gets Right That ChatGPT Does Not
Accuracy. Google's local data is updated in real-time. ChatGPT's training data has a cutoff, and even with web search, it can return outdated information. We have seen ChatGPT recommend businesses that have closed, list wrong phone numbers, and state incorrect hours.
Completeness. Google knows about virtually every business with a physical location. ChatGPT's coverage is limited by its data sources. A new business with no Foursquare listing, no Bing presence, and no web mentions simply does not exist to ChatGPT.
Maps and directions. Google integrates maps, directions, real-time traffic, and "popular times" data. ChatGPT can give you an address but cannot show you how to get there or tell you it is currently busy.
Volume. Google still handles roughly 85x more search queries than all AI search platforms combined. Ignoring Google for ChatGPT would be like closing your main store to open a kiosk.
The User Behavior Shift
Growth in AI search traffic in 2025. Users are not replacing Google with ChatGPT. They are using both for different types of queries.
The pattern we see emerging:
- Quick lookups ("pizza delivery near me") still go to Google. Users want speed and proximity.
- Research queries ("best CPA for small business taxes") increasingly go to ChatGPT. Users want curated recommendations.
- Complex needs ("I need a contractor who can remodel a 1920s bungalow kitchen") favor ChatGPT. Users want context-aware answers.
- Verification often happens on Google after getting a ChatGPT recommendation. Users cross-check reviews and check the website.
This means your business needs to show up on both platforms. A customer might discover you on ChatGPT and verify you on Google, or find you on Google and ask ChatGPT for more context. Either path needs to work.
What This Means for Your Business
The good news is that most of the work overlaps. The actions that help you on Google also help you on ChatGPT, with a few additions.
Actions that help on both platforms:
- Complete, accurate Google Business Profile with photos, hours, services, and FAQ
- Strong review profile (quantity and quality of reviews matters everywhere)
- Schema.org markup on your website (helps Google understand you and helps AI cite you)
- Consistent NAP (name, address, phone) across all directories
- FAQ content on your website answering common customer questions
Actions specific to ChatGPT / AI search:
- Claim and optimize your Foursquare listing (this is the #1 thing most businesses are missing)
- Claim Bing Places (ChatGPT uses Bing for web search)
- Build presence on Yelp, TripAdvisor, and other third-party review sites ChatGPT reads
- Create content that answers specific, nuanced questions (not just keyword-optimized pages)
- Add an llms.txt file to your website as a forward-looking practice
The bottom line: Google and ChatGPT are not competitors for your attention. They are two discovery channels serving different search behaviors. Your business needs to be found on both. The platforms that feed ChatGPT (Foursquare, Bing) are dramatically under-claimed by local businesses, which means getting there now gives you a real advantage.
How to Check Both
For Google, you probably already know your ranking. Check Google Maps, search for your business category + your city, and see where you show up.
For ChatGPT, the easiest way is to ask it directly. Or run a free AI visibility scan that checks all four major AI models at once. Either way, knowing where you stand on both platforms is the first step.
