Which AI assistants matter for a local business?
Four worth knowing: ChatGPT, Google's AI Overviews and AI Mode, Perplexity, and Microsoft Copilot. They read different sources and name different businesses, which is why a result from one says little about the others.
Which one should a local business care about most?
Google's AI surfaces and Perplexity account for about 95% of local discovery citations in the largest published study. ChatGPT is the one your customers name out loud. In practice you want to be present in the sources all of them read.
| Assistant | Reads | What that means |
|---|---|---|
| ChatGPT | Its own search index, plus Bing, plus Yelp data directly | Yelp profile and Bing Places matter more than people expect |
| Google AI Overviews / AI Mode | Google's index and Business Profiles | The Google Business Profile is the reference record |
| Perplexity | Live web search, heavy on reviews | Review volume and recency show up almost every time |
| Microsoft Copilot | Bing's index and knowledge graph | Bing Places is usually unclaimed -- cheap to fix |
Why do they name different businesses?
Because they read different sources and weigh them differently. One leans on reviews, another on its own business listings, another on whatever it retrieved this second. Averaging across them hides exactly the difference worth knowing.
It is also why any measurement worth having reports each platform separately. A single blended 'AI visibility score' is a number that cannot be acted on, because the fix for being absent from Perplexity is not the fix for being absent from Copilot.
Do I need to do something different for each one?
Mostly no. The foundations serve all of them: a readable site, clear structured data, accurate listings, steady reviews. The per-platform work is small and specific -- claiming Bing Places, completing Yelp, filling in the Google profile.
Common questions
Is Bing worth bothering with?
Almost nobody searches Bing, and a lot of assistants read it. Claiming Bing Places takes about twenty minutes and feeds both Copilot and ChatGPT's search.
Should I track all four?
Track the ones your customers use, and report them separately. Blending them into one score destroys the only information you had.

Where a figure here comes from one study we say so, because one study is one study. Where something rests on practice rather than published work, we say that instead.
If this answered one question, these answer the next ones.
How does an AI assistant decide which businesses to name?
It searches, reads a handful of pages, and writes an answer from what those pages say. So the question is not 'how do I rank' but 'which pages does it read, and is my business on them'. Usually those pages are directories, reviews and round-ups rather than your own site.
Why does AI name a different business every time you ask?
Because the answer is generated, not looked up. Ask the same question four times and you often get four overlapping but different lists. That variation is not a bug to be explained away -- it is the reason a single answer tells you almost nothing.
How can I check whether AI recommends my business?
Open ChatGPT, ask the questions your customers would ask, and write down who gets named. Do it several times, because the list changes. Ten minutes gets you an honest picture of whether this is a problem worth spending money on.
