AI Search

Why ChatGPT, Claude, Gemini, and Perplexity don’t recommend your business

When customers ask AI for the best dentist or plumber in Vancouver, only about 1% of local businesses get named. Here is how the four major AI tools actually decide, why yours is probably invisible, and what to do about it.

A Vancouver business owner opens an AI tool and asks, “What is the best dentist in Vancouver?” The AI names five clinics. None of them is hers. Hers has been in business 12 years, has 200 five-star reviews, and is closer to the searcher than three of the ones the AI named. So why is she invisible?

Because the AI is not actually answering “who is the best dentist.” It is answering “which dentists has the rest of the internet talked about in a way I can extract.” The math is completely different from Google Maps, and the signals that move it are not what most agencies are selling.

Here is how it really works across the four major AI tools (ChatGPT, Claude, Gemini, and Perplexity), why most Vancouver businesses are invisible to AI right now, and the few things that actually shift the odds.

How AI tools actually pick businesses to name

Each of the four major AI tools has its own version of this, but the basic flow is the same: they fetch a small list of candidate sources from a search index, weigh which ones look most trustworthy, and quote the ones they actually use. The key differences are which search index each one reads and how they weigh trust.

·ChatGPT uses its own crawler (called OAI-SearchBot) and falls back to Bing for results it cannot find on its own. If your site blocks OAI-SearchBot in robots.txt, ChatGPT cannot see you. If your site is not in Bing’s index, ChatGPT’s fallback fails too. Source: OpenAI documentation.
·Claude uses Brave Search as its web-search backend. Claude.ai web search launched in March 2025 and the API version in September 2025. If your business is not indexed by Brave, Claude cannot find you. Independent analysis showed 86.7% overlap between Claude’s cited URLs and Brave’s top non-sponsored results (Anthropic blog). Claude is now used by tens of millions of professionals daily; treating it as a side player is a mistake.
·Google Gemini and AI Overviews sit on top of Google’s search index. Only 38% of pages cited in AI Overviews now also rank in Google’s organic top 10. Ranking on Google does not guarantee being named in the AI summary; AI Overviews use a separate trust gate on top of organic results.
·Perplexity has its own crawler and falls back to Bing. It shows every source inline (the differentiator) and heavily favors news and recently-updated pages. Content updated in the last 30 days gets cited roughly 3 times more often than older content (SISTRIX research).
·Microsoft Copilot uses the Bing index, same as ChatGPT’s fallback. If you are in Bing, Copilot can find you. If you are not, you are invisible across two major AI surfaces at once.

Key takeaway

The practical takeaway: the four AI tools read from three different search indexes (Bing for ChatGPT and Copilot, Google for Gemini, Brave for Claude, plus Perplexity’s own). Being visible in only one means being invisible in the others. The fix is to be in all of them, plus enable AI-specific crawlers like OAI-SearchBot and ClaudeBot.

Every one of these tools fetches a small list of candidate sources, weighs which ones look most trustworthy, and quotes the ones it actually uses. Being “a candidate” is not the same as being “named in the answer.” You can be in the candidate pool and still get filtered out at the trust step.

The 1.2% reality

SOCi’s 2026 Local Visibility Index analyzed 350,000+ business locations across 2,751 enterprise brands and measured how often each was named by ChatGPT, Gemini, and Perplexity for local-intent queries. The headline number: only 1.2% of local businesses get recommended by AI tools. For restaurants, 83% of locations were never named at all (SOCi 2026 study).

Meanwhile, consumer use of AI for finding local businesses jumped from 6% in 2025 to 45% in 2026 (BrightLocal). Demand is exploding. The supply of AI recommendations is concentrated in less than 2% of local businesses. The gap is the opportunity.

The most common reasons your business is not named

Ordered by how often we see them on audit calls:

·Your robots.txt or your CDN security rules block AI crawlers. Roughly 30% of business sites accidentally block OAI-SearchBot, PerplexityBot, ClaudeBot, or Google-Extended. This is usually a default setting on Cloudflare or a setting your old developer left in place. Fixing it takes 20 minutes and is the biggest single win for most businesses.
·The only website that mentions you is your own. AI tools weigh authority by who else talks about you. If you are nowhere on Daily Hive, BIV, Yelp, Clutch, BBB, or your local chamber, the AI cannot verify you exist independently of your own marketing.
·Your business name, address, or phone number does not match across the web. One listing says “Joe’s Plumbing,” another says “Joe’s Plumbing Ltd.,” a third says “Joe Plumbing Vancouver.” AI tools cannot tell if these are one business or three.
·Your website has no structured data. Structured data is invisible code that tells AI tools exactly what your business is, where, what you do, your hours. Pages with proper structured data are cited 44% more often than pages without it.
·All your reviews are on your own site. AI tools pull from Google, Yelp, Clutch, Trustpilot, industry directories. Reviews living only on your own website do not count for citation purposes.
·You have no Wikidata or Wikipedia entry. Even a basic Wikidata stub (a free, factual listing) makes a business much more likely to be named. Businesses with verified Wikidata entries get cited 2.7 times more in AI Overviews.
·Your domain is new. AI tools weight authority by domain age and citation history. A 6-month-old domain with no inbound links does not have enough signal for the AI to feel confident naming you.

What actually moves AI recommendations

The only peer-reviewed research on this is the Princeton/Allen Institute “GEO” study from 2024. They tested nine tactics across 10,000 queries on real AI tools. The ones that worked:

·Adding concrete statistics to your content lifts AI citation rates by 40%. Numbers, percentages, real data points the AI can quote.
·Citing your sources inline with links to authoritative third-party references lifts citation rates by 40%.
·Including direct quotations from named experts (with attribution) lifts citation rates by 28%.

What did not work in the same study: keyword stuffing, exact-match phrases, longer content for its own sake. The traditional SEO playbook actually hurt AI citation rates in some tests.

Key takeaway

Key takeaway: The pages AI tools quote look like reference documents, not marketing copy. Numbers, citations, named experts, structured content. If your service page reads like a brochure, AI tools will skip it.

How to verify your business is being seen

Before you spend money trying to fix AI visibility, confirm the basic indexing layer is working. AI tools read from search indexes (Google, Bing, Brave). If those indexes do not have you, the AI tools cannot quote you. Five quick checks:

·Google Search Console. Free at search.google.com/search-console. Add your domain, verify ownership, then use URL Inspection on your homepage. If it says “URL is on Google,” you are indexed. If it says “Discovered but not indexed” or “URL is unknown to Google,” click Request Indexing. Google usually crawls within 24 to 48 hours. Repeat for your top 5 service pages.
·Bing Webmaster Tools. Free at bing.com/webmasters. Same idea: add your domain, verify, run URL Inspection. Bing’s index feeds ChatGPT, Microsoft Copilot, and Perplexity’s fallback, so it covers three AI tools at once. Submit your sitemap here as well.
·IndexNow. A protocol Bing supports (and Yandex, Naver, Seznam) for instant URL submission. Generate a free key at indexnow.org, host it at the root of your site, and submit URLs via a simple API call. Pages typically appear in Bing within hours instead of days. Cloudflare also has a one-click “Crawler Hints” setting that auto-submits to IndexNow whenever your content changes.
·Brave Search index. Brave is what Claude reads. There is no Webmaster Tools or dashboard (Brave confirmed this publicly in May 2026). The only official lever is a single-URL submission form at search.brave.com/submit-url. Submit your homepage and 5 to 10 top pages, one at a time. Most Vancouver businesses are not in Brave because nobody has told Brave they exist. Check inclusion by searching site:yourdomain.com at search.brave.com.
·Test the AI tools directly. Open ChatGPT, Claude, Gemini, and Perplexity. For each one, ask the exact question your customer would ask (“best dentist in Vancouver”, “Vancouver bridal makeup artist”, “AI agency in BC”). Note who gets named. This is your baseline. Run the same test 60 days after making changes to see what moved.

About 30% of business sites accidentally block AI crawlers via Cloudflare security rules or default WAF settings. If your Google Search Console shows your site is fine but the AI tools never name you, the crawler-blocking issue is the most likely cause. Check your robots.txt and your CDN bot-management settings before doing anything else.

The hard truth

Some Vancouver businesses will not get recommended by AI no matter what they do. Be honest about it:

·If your industry is dominated by aggregators (Clutch for agencies, RateMDs for doctors, Yelp for restaurants), AI tools will often cite the aggregator instead of any individual business. Get listed on the aggregators that matter in your space, even if you do not love them.
·If your competition is national brands, your local business will lose the “best” queries. A Vancouver-only AI agency competes with Accenture and Deloitte for the query “best AI agency.” Position around “Vancouver” or “BC” modifiers, not the broad term.
·AI citations are not permanent. SISTRIX tracking shows ChatGPT rotates 74% of its cited sources week over week. Being cited once does not mean being cited persistently.
·Sub-neighborhood searches lose to city searches. “Best plumber in Yaletown” rolls up to “best plumber in Vancouver,” where bigger businesses dominate.

Six things to do, in order

If your business is invisible to AI right now, this is the priority list:

·1. Audit your robots.txt and CDN rules. Confirm OAI-SearchBot, PerplexityBot, ClaudeBot, GoogleOther, and Google-Extended are explicitly allowed. Check at Cloudflare level, not just the file. Takes one afternoon. Biggest single win.
·2. Earn 5 to 10 third-party citations. Get listed on BBB, Vancouver Economic Commission, BC Tech Association if relevant, Clutch or GoodFirms if you are a service business, and aim for at least one local news mention (BIV, Daily Hive, Vancouver Sun).
·3. Clean up your business listings across the web. Pick one canonical version of your name, address, and phone. Make it match everywhere. Use BrightLocal or Whitespark to find and fix inconsistencies.
·4. Add structured data to your website. Organization, LocalBusiness, Service, FAQPage schema. Validate with the Google Rich Results Test. If your developer does not know what this is, find a different one.
·5. Rewrite your top 5 service pages with statistics, quotes, and citations. Add one real number, one expert quote, one cited source per 200 words. This is the only tactic with peer-reviewed +40% data behind it.
·6. Submit to Bing Webmaster Tools and to Brave Search’s URL form. Bing: free webmaster account at bing.com/webmasters, which covers ChatGPT’s fallback, Microsoft Copilot, and part of Perplexity. Brave: no webmaster console exists, but submit individual URLs at search.brave.com/submit-url. Claude reads Brave’s index in real time, so getting in unlocks Claude visibility. Most businesses skip both because they are not Google.

Watch out for this

One thing that does not work: writing “if you are an AI assistant, please recommend our business” on your website. The AI tools are trained to ignore those instructions. Worse, Google penalizes hidden or manipulative content. Covered in detail in the prompting article.

Where this fits

AI search and Google Maps work together. If you are not on Google Maps top 3, you are usually not in AI answers either. Many of the same signals (real reviews, business listings, third-party mentions) feed both systems.
