AI Overviews, AI Mode and ChatGPT Are Not the Same Thing

The one number that tells you these are three different products

Google runs two AI answers. Same company, same index, same day, same question. They cite the same web pages 13.7 percent of the time.

Ahrefs' AI Overviews vs AI Mode study got that figure by comparing 540,000 pairs of AI Overview and AI Mode responses to identical queries. The two surfaces agreed on what to say 86 percent of the time. They almost never agreed on who deserved the credit.

Now add ChatGPT, which is not Google at all. Different company, different crawlers, different way of finding a local business.

This page defines each surface and stops there. There is no ranking advice anywhere in it, which is on purpose. You cannot judge a proposal about something you cannot describe, and every other explainer we read jumped to optimization tactics inside 400 words. If you want the ranking side, that lives in why AI does not recommend your business and in our breakdown of where AI chatbots get their data.

AI Overviews: the box that appears whether you asked for it or not

Google's own description is short. AI Overviews are an "AI-generated snapshot with key information and links to dig deeper," shown "when our systems determine that generative AI can be especially helpful."

You do not opt in. Google states the feature cannot be turned off, though selecting the Web filter after a search returns text links only. On a phone it often fills most of the first screen.

Three facts matter for a local business owner, and they pull in different directions.

It is the highest-volume AI surface by a wide margin. Google said in March 2025 that AI Overviews were used by more than a billion people, and Whitespark's Q1 2025 study found them appearing on an average of 68 percent of local searches.

It is also the stingiest about naming anyone. In the Ahrefs comparison, 59.41 percent of AI Overview responses named no brand or business at all, against 34.66 percent for AI Mode. When it does name someone, it averages 1.3 entities per answer.

And it has stopped being a mirror of page one. Ahrefs found in March 2026 that only 38 percent of pages cited in AI Overviews also rank in Google's top 10 for that query, down from roughly 76 percent in its own July 2025 measurement. Anyone still telling you to rank first and let the AI follow is quoting a number that has halved. We covered what that decoupling did to one profession in what AI Overviews did to law firm traffic, and the mechanics in how local businesses rank in AI Overviews.

AI Mode: the tab, not the box

AI Mode is a place you go, not a thing that happens to you. Google calls it "Google's most powerful AI search experience," reachable at google.com/ai, by tapping the AI Mode tab after a search, or from the Google app home screen.

Under the hood it does one thing that explains almost every difference on this page.

Your one question becomes many questions. So the answer runs about four times longer than an AI Overview, names more businesses (3.3 entities on average against 1.3), and fails to cite its sources less often (3 percent of responses against 11 percent).

Wider is not automatically better for you. Semrush's 5,000-keyword study found AI Mode showed a link sidebar on 92 percent of queries carrying roughly seven unique domains, against about three in AI Overviews. More slots, but a source list that matched Google's own top 10 only about 54 percent of the time. Extra room is not the same as an extra chance if the room is filled from a different list.

AI Mode is also the only surface here where Google documents personalization in plain language. Personalization is "available if you're 18 or older and have history and personalized recommendations enabled."

That is why the map results your nephew shows you and the ones you see on your own phone can legitimately disagree. It is also why Google Maps ranking and AI Mode visibility have to be tracked as two separate things.

ChatGPT: a different company's product that happens to search

ChatGPT is not a Google feature. OpenAI builds it, and OpenAI reaches the web through its own crawlers, which OpenAI documents by name.

That documentation contains the most useful sentence in this entire subject for a business owner. OpenAI states that "Sites that are opted out of OAI-SearchBot will not be shown in ChatGPT search answers, though can still appear as navigational links." OAI-SearchBot is the crawler that governs whether you can be named. GPTBot, the one most people block on a developer's advice, is for model training and is a separate decision.

On scale, use the census-grade number rather than the vendor one. Pew Research surveyed 5,119 US adults in February 2026 and found 44 percent use ChatGPT against 24 percent for Gemini. BrightLocal found ChatGPT is the most-used AI tool for local business recommendations at 31 percent of consumers, with Google's AI Mode second at 23 percent.

Citation behavior differs again. Semrush's analysis of 126 million prompts found ChatGPT cites an average of 15 sources per response while Gemini cites 3. Being named more often is not the same as being visited more often: Ahrefs estimates Google still sends 190 times more referral traffic to websites than ChatGPT does.

For local questions specifically, Damian Rollison of SOCi documented in May 2025 that ChatGPT runs a Bing search for the query, collects 20 to 30 of the top results, and reorganizes them with its own logic. It was not reading Bing Places, and it does not read your Google Business Profile directly. Worth knowing before anyone invoices you for "ChatGPT listing management," and worth reading alongside whether customers really use ChatGPT to find local businesses and what to do when ChatGPT has wrong information about your business.

Three names people get wrong, including some agencies

Gemini is not AI Mode. Gemini is Google's standalone chatbot app at gemini.google.com. AI Mode is a tab inside Google Search that runs on Gemini models. Same engine, different vehicle, and they behave differently: Gemini averages 3 cited sources per response where ChatGPT averages 15.

ChatGPT Search is not a separate product you can be listed in. It is ChatGPT deciding to run a search. There is no directory, no submission form, and no listing to buy. OpenAI publishes crawler documentation, not a listings program. Anyone selling you a spot is selling you something that does not exist.

And there is a technical trap worth naming plainly, because it is the one thing on this page that can silently zero you out. Google states in its AI features documentation that to appear in either of its AI features, "a page must be indexed and eligible to be shown in Google Search with a snippet." A nosnippet tag left behind by a previous developer removes you from both surfaces at once. That is a statement about eligibility, not a tactic, which is also why the schema markup question and the GEO versus SEO question are separate arguments from this one.

What your business actually shows up as inside each one

Here is the part nobody writes down. In each surface your business is a different object made of different parts.

Two of those rows deserve a warning label.

The AI Mode place card looks like a Google Business Profile because it draws on the same underlying place data. It is not the same result set. Sterling Sky found AI local packs surfaced 5,943 unique businesses against 18,330 in traditional three-packs across the same 322 markets, roughly a third as many winners, with 88 percent of markets showing fewer.

Sterling Sky also reports that AI local packs frequently show one or two businesses rather than three, carry no call buttons, and at the time of the report ran on roughly 7 percent of tracked keywords, mobile only, United States only. A surface with no call button is a different commercial object from one with a call button, whatever the map looks like. That distinction is the whole reason we treat AI marketing as separate work from local pack work rather than a rename of it.

Set your expectations before you open the last two. Google's Search Console report shows impressions, pages, countries and devices. It does not show clicks or the queries behind them, and it counts AI Overviews and AI Mode together in one number rather than splitting them. Microsoft's AI Performance report goes a step further and exposes what it calls grounding queries, meaning the subqueries the AI actually ran.

There is no report at all for ChatGPT. Any vendor showing you a ChatGPT visibility percentage is sampling prompts and estimating from that sample. That is a legitimate method, and it is not a log file, and the difference should be stated out loud on the invoice.

The three questions to ask whoever is selling you this

Most of the confusion in this market is a naming problem, and fixing it costs you one conversation.

"Which surface do you mean?" AI Overviews, AI Mode and ChatGPT are three products with three source lists. The 13.7 percent citation overlap is between two features inside the same company. Across companies the gap is wider still, and a proposal that says "AI" without saying which one has not told you what you are buying. That is the same test we apply in is AI SEO worth paying for.

"What will you show me at the end of the month?" For the two Google surfaces the honest answer is Search Console impressions, with no clicks and no queries. For ChatGPT the honest answer is a sample of prompts, because OpenAI publishes nothing else. Any answer that sounds more precise than that is describing a tool's estimate, not a measurement. More on separating the two in how to tell if your SEO agency is working.

"Does this replace what I already do?" It does not, and the consumer research says so bluntly. BrightLocal's consumer search behavior research found 45 percent of consumers now use AI for local recommendations, up from 6 percent a year earlier. In the same body of work only 18 percent felt ready to contact the business the AI named, and 43 percent of the people who started on AI went to Google afterward to check.

That last pair of numbers is the entire picture in one line. AI is now where a large share of people start and almost nobody finishes. Everything else we publish on this sits in the blog index.
