# What AI Search Actually Is (and Why Your Google Ranking Doesn’t Help)

*2026-03-31* · *How It Works*

> We’ve run over 5,000 AI queries for local businesses. AI search doesn’t work like Google. Each platform recommends different businesses, and your Google ranking barely matters.

You already know how Google works. Someone searches “plumber near me,” Google shows a list of businesses sorted by reviews, distance, and profile quality. You can influence where you land by keeping your Google Business Profile updated, collecting reviews, and staying active.

AI search is different. We know because we’ve tested it. Over the past several months, we’ve run more than 5,000 queries across ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews for local businesses in dozens of cities. What we found doesn’t look anything like Google.

## What are ChatGPT, Perplexity, and Google AI Overviews actually doing?

AI search tools like ChatGPT, Perplexity, Gemini, Claude, and Google’s AI Overviews don’t show a list of links. They give a direct answer: “Here are three good plumbers in your area.” No scrolling. No ads. No ten blue links. Just a recommendation.

For the person asking, it’s faster and easier. For the business being recommended, it’s incredibly valuable. For the business that isn’t being recommended, it’s a problem they don’t even know they have.

And these tools do recommend businesses by name. In our study of 600 home service queries, AI named a specific local business 87% of the time. In eye care, 70%. These aren’t vague suggestions. They’re names, addresses, and recommendations.

## How does AI decide which businesses to recommend?

Google ranks websites based on signals it checks in real time: your reviews, your location, your profile activity, your website content. Update your Google Business Profile today and it can affect your ranking this week.

AI tools work differently. They’re trained on a massive snapshot of the internet, sometimes months or even a year old. When someone asks ChatGPT for a plumber recommendation, it isn’t searching the web live. It’s recalling what it learned during training.

What did it learn from? We tracked every source citation across thousands of queries. The answer depends on your industry. For plumbers and HVAC contractors, BBB is the top source AI tools cite, followed by Yelp and Angi. For eye doctors, Healthgrades and Zocdoc account for 59% of all AI citations. For landscapers, Yelp leads. Your website matters too, but only if it has enough specific content for the AI to learn from.

If your business appears across many of these sources with consistent information (same name, same address, same phone number, same services), the AI is more likely to recommend you. If you only appear in one or two places, the AI may not know you exist at all.

## Does every AI platform recommend the same businesses?

No. This is the finding that surprised us most.

In our home services study, we identified 1,571 unique businesses across four AI platforms. 80% of them were recommended by only one platform. Only 23 businesses, 1.5%, appeared on all four. Ask ChatGPT for a roofer and ask Perplexity the same question in the same city: you will almost certainly get different names.

In eye care, the fragmentation was even worse. 97.8% of practices appeared on only one platform. Zero appeared on all five. ChatGPT and Gemini, the two largest platforms, agreed on exactly zero eye doctor recommendations.

> Being visible on one AI platform gives you almost no visibility on the others. Each one is pulling from different data sources, weighting different signals, and arriving at different answers.

## What about Google’s AI Overviews?

Google now sometimes shows an AI-generated summary at the top of search results. These are called AI Overviews. They pull from Google’s own index, so your Google Business Profile does help here.

But here’s the problem: Google AI Overviews are wildly inconsistent. In our home services study, they triggered on every query in Portland and Nashville but returned zero results in Raleigh-Durham and Tucson. Same queries, completely different experience. In eye care, Google AI Overviews triggered on just 4% of queries. For pediatric eye doctors, the rate was 0%.

Meanwhile, ChatGPT and Gemini answered nearly 100% of the time. The platform most businesses spend all their time optimizing for is the one performing worst in AI search.

## What determines whether AI recommends your business?

Based on our audits across multiple cities and industries, five factors consistently separate AI-visible businesses from invisible ones.

First: presence across multiple platforms. Not just Google. In our data, the businesses that appeared on all four AI platforms had profiles on BBB, Yelp, Angi, and at least two other directories. A business with 50 Google reviews but nothing elsewhere has a thinner profile than one with reviews spread across four or five sites.

Second: directory and citation consistency. If your business name is “Joe’s Plumbing LLC” on Google but “Joe’s Plumbing” on Yelp and “Joseph’s Plumbing” on BBB, AI may treat those as three different businesses.

Third: earned mentions. Articles, roundup lists, press coverage. These third-party signals tell AI a business is established and trusted.

Fourth: website content that matches how people ask questions. We ran 32 queries for a Tampa managed print company. It showed up twice. The competitor cited six times across all platforms wasn’t the biggest company. It was the one with a page titled “Managed Print Services in Tampa Bay: What It Costs and How to Choose a Provider.” That page directly matched how AI structures its answers.

Fifth: how long you’ve been around. AI models tend to surface businesses with a longer history of web mentions. A company online since 2005 has 20 years of accumulated data. A company that launched last year has almost none.

This isn’t fair. But it’s how it works.

> In our audit of HVAC companies in Mandeville, LA, we found a contractor with a perfect 5.0 rating on Angi and 16 years of experience. Customers love him. But with listings on only one or two platforms, none of the AI tools we tested had ever heard of him. Meanwhile, a national franchise with a 1.7 Yelp rating showed up in every AI result because its brand name appears on thousands of web pages.

## What should local businesses do about AI search right now?

Your Google ranking still matters. People still search on Google. That’s not going away.

But Google is no longer the only place people look. And the businesses that show up in AI search aren’t necessarily the best businesses. They’re the ones with the widest, most consistent web presence. That’s a different thing.

The good news: the steps that improve AI visibility (more directory listings, consistent business data, earning mentions, building website content) also help your Google ranking. They’re not competing priorities. But if you’re only focused on Google reviews and nothing else, you’re building on one platform while an entire new channel of customer discovery is passing you by.
