Whether ChatGPT can recommend a business that does not rank on Google, and what else the engines read

The short answer

The eligibility rule OpenAI publishes for ChatGPT search names its own crawler, not a Google ranking. ChatGPT searches through OpenAI's own crawler and outside search providers, reads the pages it finds, and names the businesses those pages describe. Claude and Perplexity each document a search crawler of their own as well.

Whether the engines do name Phoenix contractors that Google does not show is a separate question, and one we measure rather than assume. We compare the businesses Google shows for Phoenix home-services searches with the businesses the four AI engines name, and we report a figure for businesses named by the engines but not shown by Google only when the count is large enough to support a claim. Our latest measurement of businesses the engines named that Google's results did not show: 5¹. As a share of the 11² businesses the engines named: 45%³. If those figures read "not yet measured", our data does not yet support the claim, and this guide does not make it.

The practical answer for an owner does not depend on that number. What the engines read is broader than Google's results, and every part of it can be worked on.

How we measure it

We take a snapshot of what Google shows for the searches a Phoenix homeowner makes when hiring in each trade we cover. A business counts as shown by Google if Google Places lists it in the top 20 for any of those searches or, where the snapshot captures Google's results page, it appears in the local pack or the top 10 organic results.

We compare that with the businesses ChatGPT, Claude, Perplexity, and Gemini named in their answers over recent weekly runs. A business the engines named that the snapshot never showed is a candidate for this guide's question.

We hold that figure back until it can bear weight. It is reported only when the snapshot's Google lookups all succeeded, since a failed lookup could be exactly where Google showed the business, and only when there are enough such businesses, both in number and as a share of the businesses the engines named, that a few odd cases cannot make the headline. Below that, the figure reads "not yet measured". The comparison, its dates, and its caveats are on our Google vs AI research page.

Two limits apply even when the figure is reported. A business that Google did not show for our searches may still rank for other searches, or for its own name. And an engine naming a business once is not the same as recommending it every time.

Why a Google ranking is not the gate

Each engine that answers with live search reaches the web through its own documented route.

ChatGPT. OpenAI says OAI-SearchBot⁴ is the crawler it uses to surface websites in ChatGPT's search features. Its help center states the eligibility rule in one sentence: allow OAI-Searchbot to crawl the site⁵, and confirm the host or content delivery network allows traffic from OpenAI's published search-bot IP addresses. That rule names OpenAI's crawler and OpenAI's addresses, not a Google position. OpenAI's help center for business workspaces also says ChatGPT may share search queries with Bing⁶ to return web results.

Perplexity. Perplexity documents PerplexityBot⁷ as the crawler designed to surface and link websites in its search results.

Claude. Anthropic indexes pages for Claude's search results with Claude-SearchBot⁸, and says that disabling it may reduce a site's visibility in those results.

Gemini and Google's AI features. Google is different, because its AI features sit on Google's own index. Google says there are no additional requirements⁹ to appear in AI Overviews or AI Mode beyond being indexed and eligible to show in Search with a snippet. Being indexed is not the same as ranking near the top: Google also documents that these features may use query fan-out¹⁰, running several related searches across subtopics to build one answer. The pages behind one of Google's AI answers are the results of several searches, not only the one the homeowner typed.

What the engines draw on besides Google

If a Google position is not the gate, what is? The engines' answers about local businesses are built from a few kinds of pages.

Directories and review sites. BrightLocal found Yelp used as a source in 33%¹¹ of its local test searches across ChatGPT Search, Gemini, Google AI Mode, and Perplexity. Yext, studying citations on location-specific questions, found 86%¹² of citations came from sources brands control or manage, such as their own websites and listings. Both are vendors with an interest in listings, and Yext's study did not include home services, but both point to the same place: listings and profiles you can edit.

Reviews. SOCi reports that locations ChatGPT recommends average 4.3-star ratings¹³. That is a correlation across large multi-location brands, not a rule, but it is a reason to treat your review profiles as something the engines read.

Your own website. A page can only be used if the engine's crawler can reach it. A site that blocks OAI-SearchBot, Claude-SearchBot, or PerplexityBot, on purpose or through a host's security settings, drops out of that engine's reading list whatever its Google position.

What Phoenix answers actually cite. In our weekly Phoenix measurements, the engines cited 154¹⁴ distinct websites across home-services questions, and the one they cited most was energyshieldwindowsanddoors.com¹⁵. The full list, by trade and by engine, is in which websites AI assistants cite for Phoenix contractors.

What this does not mean

It does not mean Google stops mattering. Gemini and Google's AI features draw on Google's index, and Google's own local results remain a channel of their own. A business that ignores Google gives up that channel and the AI features built on it.

It does not mean an AI recommendation is easy to get. An answer names a handful of businesses. Being readable is the entry fee, not the prize.

And it does not mean anyone can promise you a place in ChatGPT's answers. Nobody controls them, including us.

What this means for an owner

If you are not ranking on Google, you do not have to wait until you are before working on AI visibility. The steps below do not depend on your Google position.

• Open the door. Make sure your robots.txt and your host allow the search crawlers: OAI-SearchBot, Claude-SearchBot, PerplexityBot, and Googlebot. Our guide to llms.txt and AI crawler access covers the details.
• Be where the engines read. Get listed, accurately and consistently, on the directories and review sites the engines cite for your trade in Phoenix.
• Earn reviews on those sites, not only on Google.
• Publish pages worth quoting. One page per homeowner question, with specifics from your own work.

Then measure it on every engine, over weeks. If you do rank on Google and the engines still leave you out, the reasons are in why your business ranks on Google but ChatGPT does not mention it.
