ChatGPT vs Google AI Overviews: which one sends local customers
Both send local customers; they do it differently. Google’s AI Overviews sit in front of an enormous share of ordinary searches, so they reach customers who never chose to use AI at all. ChatGPT answers the deliberate ask: someone opened an assistant and asked who to hire. Reach versus intent is the honest comparison, and the encouraging part for a busy owner is how much of the work behind both is the same work.
The short answer, hedged only where the data forces it
Google’s AI answers touch more local searches today because they’re bolted onto the search behavior people already have: by early 2025, 18% of Google searches showed one. ChatGPT’s answers carry more deliberate intent per asking, from a base of 900 million weekly users. Neither number tells you which sends more customers to your business specifically, and anyone who claims a universal winner is past their data.
The two source figures, named: the 18% share is Pew Research Center’s March 2025 browsing study1, and the ChatGPT user base is OpenAI’s figure as reported in February 20262.
How each one builds its answer
Different plumbing, worth knowing. Google’s AI surfaces run searches over Google’s own index, including a “query fan-out” that issues multiple related searches per question, and they sit adjacent to the Business Profile and map ecosystem Google already runs4. ChatGPT searches the web when a question needs current information and links its sources3, with its index arrangements being a story of partnerships that keeps changing. Same question, two different reading lists, which is exactly why a business can be named on one and absent from the other.
Same ten questions, both platforms
Where they tend to agree, and why that’s good news
Both read reviews, business profiles, directories, and your own pages; the overlap in inputs is much larger than the difference in interfaces. A business with strong shared fundamentals tends to travel across surfaces, which is why the fundamentals-first strategy survives every platform comparison, this one included.
Which one deserves your effort first
Our opinion, conditioned honestly: neither, as a target. Chasing a platform means tuning for an interface that changes monthly; feeding the shared sources means both platforms read your improvements. Where conditioning matters: if your customers skew toward habitual Google search (most trades, most emergencies), Google’s surfaces will show your fundamentals to more people sooner; if your market researches deliberately (higher-ticket, less urgent decisions), assistant conversations matter relatively more. Either way you only know what’s true for your business by watching both, which is what tracking across platforms is for.
