How AI Answers Choose Local Businesses, in the Platforms' Own Words

Synopsis

How AI answers choose local businesses is mostly explained by the platforms themselves, in a handful of public help pages, and the short version is this: the AI layers sit on top of ordinary search and maps. Google says there is nothing extra to do to appear in its AI features beyond being a normal, indexed, helpful page. Microsoft says Copilot relies on “the same core crawling, indexing, and ranking foundation as traditional search.” OpenAI and Perplexity say the main thing is to let their search crawlers read your site.

I read every primary source I could find from all four in October 2026, quoted the lines that matter below, and marked where a company says nothing. Then I turned it into a short list an owner can work through in an afternoon. Anything that is my inference rather than their words is labelled as mine.

Why This Is Worth Reading From the Source

Most advice about “ranking in ChatGPT” is guesswork repeated until it sounds like fact. Some of it is useful, a lot of it is someone selling a tool. The platforms do publish guidance, it is short, and it is more boring than the folklore, which is exactly why it is worth reading. If a tactic contradicts what the platform itself says, I would not spend money on it.

Google: The Map Pack and the AI Features

Google is the clearest of the four, because it publishes two separate things: how local results are ranked, and what its AI features need.

For local results, Google’s Business Profile help page, Tips to improve your local ranking, names three ideas:

• “Relevance is how well a Business Profile matches what someone is searching for.”
• “Distance refers to how far each business is from the customer who’s searching.”
• “Prominence means how well-known a business is.”

The same page says “Businesses with complete and accurate info are more likely to show up in local search results” and “More reviews and positive ratings can help your business’s local ranking.” That is close to the whole official story. You cannot change distance. You can change relevance (what your profile and site say you do) and prominence (reviews, mentions, how well known you are).

For AI Overviews and AI Mode, Google’s page on AI features and your website is blunt: “There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary.” It goes further: “You don’t need to create new machine readable files, AI text files, or markup to appear in these features.” The one technical condition is that “a page must be indexed and eligible to be shown in Google Search with a snippet.”

Underneath both sits Google’s helpful content guidance, which says its systems aim to prioritize “helpful, reliable information that’s created to benefit people.” Two of its self-check questions are worth taping to the wall: “Does the content provide original information, reporting, research, or analysis?” and “Does this content demonstrate first-hand expertise and a depth of knowledge?”

On structured data, Google’s LocalBusiness documentation says the markup lets you “tell Google about business hours, different departments within a business, reviews” and more, with name and address as the only required fields. Note what the AI features page said above: no special markup is required for AI answers. Markup helps Google read the facts; it is not a ticket into the answer.

Microsoft: Bing, Bing Places and Copilot

Microsoft’s Bing Webmaster Guidelines now cover Copilot directly. They describe how Bing “surfaces content across Bing search experiences, Copilot, and grounding API results,” and they make the same point Google makes: “Bing and Copilot search experiences rely on the same core crawling, indexing, and ranking foundation as traditional search.”

A few lines from that page are unusually practical for a local business:

• “Grounded answers and citations depend on content that Bing can clearly interpret and verify.”
• “Use clear and consistent naming for people, organizations, products, and locations.”
• “Place essential information near the top of the URL.”
• On structured data: it “may support clearer grounding but does not guarantee visibility or grounding traffic. Markup must accurately reflect visible content.”
• On updates: use IndexNow, because “timely notifications help Bing refresh the index and reduce outdated or incorrect URL references in Copilot responses.”

Bing’s general explainer, How Bing delivers search results, lists relevance, quality and credibility, user engagement, freshness, location and page load time, with location described as “the user’s location (country and city), where the page is hosted, the language of the page.” For the map side, Microsoft runs Bing Places for Business, its equivalent of the Google Business Profile. Copilot draws on Bing, so a Bing Places listing that matches your Google profile is cheap insurance.

OpenAI: ChatGPT Search

OpenAI publishes less about how ChatGPT picks a business. What it does publish clearly is about its crawlers, on its bots documentation:

• “OAI-SearchBot is used to surface websites in search results in ChatGPT’s search features.”
• “Sites that are opted out of OAI-SearchBot will not be shown in ChatGPT search answers, though can still appear as navigational links.”
• GPTBot is different: it “is used to crawl content that may be used in training our generative AI foundation models.”

That distinction matters. You can block training (GPTBot) and still allow search (OAI-SearchBot). Block the search crawler and, by OpenAI’s own wording, your site will not be shown in ChatGPT search answers.

Beyond that, I could not find an OpenAI page that explains how ChatGPT ranks or chooses one local business over another. My inference, and it is only that: when ChatGPT answers “who should I call” with live results, it leans on search results and business listings from other providers, so the same basics that win on Google and Bing carry over. Treat anyone who claims to know OpenAI’s local ranking formula with suspicion.

Perplexity

Perplexity’s crawler documentation says PerplexityBot is designed to “surface and link websites in search results on Perplexity” and is “not used to crawl content for AI foundation models.” Its advice is a single line: “To ensure your site appears in search results, we recommend allowing PerplexityBot in your site’s robots.txt file.” Perplexity publishes nothing I could find on how it ranks local businesses.

What They Agree On

Read side by side, the four companies say the same handful of things, in different words:

1. Be readable. Let the search crawlers in. Google needs the page indexed with a snippet; Bing needs it discoverable; OpenAI and Perplexity name their search bots and tell you to allow them.
2. Say plainly what you do and where. Google’s “relevance,” Bing’s “clear and consistent naming” and “essential information near the top.”
3. Be accurate and consistent everywhere. Google’s “complete and accurate info,” Bing’s “content that Bing can clearly interpret and verify.”
4. Be well known, honestly. Google’s “prominence” and its line on reviews and ratings.
5. Do not buy a shortcut. Google says no special file or markup is required for its AI features; Bing says markup does not guarantee visibility.

What This Looks Like on Calgary Trade Websites

Earlier this month we checked the homepages of 50 Calgary trade businesses against several of these points on 3 October 2026 (the full study). The good news is that almost nobody is locking the AI search crawlers out: 1 of 50 robots.txt files blocked a crawler, and it was CCBot, not a search bot. The gap was elsewhere. 33 of 50 carried business markup Google recognises, 15 had none at all, and only 25 of 50 put their hours in the page text, which is exactly the kind of plain fact Bing says it needs to “interpret and verify.”

A Checklist You Can Do This Week

None of this needs a new tool. In rough order of effort:

• Robots.txt: open yoursite.com/robots.txt and make sure it does not block Googlebot, Bingbot, OAI-SearchBot or PerplexityBot. Blocking GPTBot (training) is your call and does not remove you from ChatGPT search.
• Google Business Profile: complete every field you can: primary and secondary categories, services with prices where you are comfortable, service area, hours, photos. Google says complete and accurate info helps.
• Bing Places: claim it and make it match Google exactly.
• Name, address, phone: the same spelling and format on your site, your profiles and every directory you control.
• Your homepage: say what you do and where in the first lines of plain text, not only in a photo. “Furnace repair and installation in southwest Calgary” beats “Comfort you can count on.”
• Hours and phone in text, near the top, on the page itself.
• Reviews: ask every happy customer, and reply to every review. Google names reviews and ratings directly.
• Markup: add LocalBusiness structured data that matches what the page shows. Helpful, not magic.
• Be mentioned: local associations, suppliers, community pages and press that name you and link to you are what “well-known” looks like from the outside. This is my inference from Google’s “prominence,” not a published formula.
• Tell the engines when you change things: submit a sitemap in Search Console and Bing Webmaster Tools, and use IndexNow if your site supports it.
