Key takeaways
- AI tools build their answers from sources across the web, and those sources change from country to country. What works for a plumber in Phoenix may not work for one in Pretoria.
- Every market shares a global layer: your Google Business Profile, Apple Maps, Bing Places, Facebook and your own website. Get that right first.
- On top of it, each country has its own directories, review platforms and trade sites. That’s where most businesses have gaps.
- Almost no research has been published on AI sources outside the US, so the most reliable method is to check which sources AI cites for your own searches.
“Every guide I read about AI search is American. Does any of it apply to my business in South Africa?”
Some of it does. Much of it doesn’t. The advice to “get on Yelp” is sound in Chicago and close to useless in Cape Town, where few customers use it. The review site a UK customer trusts before hiring a builder isn’t the one an Australian customer checks.
That matters, because AI tools don’t invent their recommendations. They assemble them from sources they can find and trust. If those sources are different in your country, your strategy needs to be different too.
This guide covers what’s the same everywhere, what’s different in each of the four markets we work in, and a simple method for finding the sources AI actually uses for your business, wherever you are. If you’re new to the idea, start with What is GEO? A plain-English guide for business owners.
1. Why does AI recommend businesses differently in each country?
Because AI tools build answers from the sources they can find for each search, and those sources are local. Each country has its own directories, review platforms, trade sites, news outlets and even words for the same service. The engines also differ from each other, so there’s no single list that works everywhere.
Here’s what AI draws on when it recommends a local business. A BrightLocal study of ChatGPT’s local search sources in the US found that 58% were business websites, 27% were mentions of businesses on other sites, and 15% were directories. Many of those directories and mentions are specific to a country, or even a city.
The engines don’t agree with each other much either. Formative Digital’s research on AI local search found 83.7% of the sources cited in its tests were unique to a single AI engine. It also reports a separate US test in which ChatGPT and Perplexity shared only 6.5% of their citations for the same local questions. Different engines, different sources.
Then there’s language. South Africans say “geyser”, Americans say “water heater”, and the British say “boiler”. In South Africa, some customers will search in Afrikaans or isiZulu. AI tools match the words customers use, so your content and listings need to use them too.
2. What’s the same in every market?
Every market shares a global layer: your Google Business Profile, Apple Maps, Bing Places for Business, Facebook, and your own website. These feed AI tools in every country. Get them complete and consistent before you work on anything country-specific.
Your Google Business Profile. Google’s own AI features lean on it heavily. BrightLocal’s 2025 study of AI local sources found that Google’s AI Mode displayed Business Profile information even when it wasn’t the main cited source. If you do one thing, do this well. Google Business Profile mistakes that quietly cost you calls covers what to check.
Your website. It was the single biggest source type in BrightLocal’s ChatGPT study. Clear service pages, your area and your contact details, stated plainly, near the top. How to write content AI actually quotes shows how.
Bing Places for Business. Often ignored, but worth ten minutes. OpenAI says ChatGPT’s search draws on third-party search providers, and Microsoft’s Bing is widely reported to be one of them. A complete Bing listing costs nothing.
Apple Maps and Facebook. Both appear near the top of Whitespark’s citation lists for all four markets, and Apple Maps is what iPhone users see by default.
3. What matters in South Africa?
In South Africa, get listed on the country’s main directories, like Yellowpages.co.za, Brabys and SAYellow, and take Hellopeter seriously as the review platform many South Africans check. Use local language and place names, and check what AI cites for your own searches, because almost no South African research exists yet.
Directories. Whitespark’s list of top citation sources for South Africa includes, after the global platforms: Central Index, Foursquare, Yellowpages.co.za, Brabys, SAYellow, YelloSA, Fyple, MySheriff, Cylex, HotFrog, ActiveWeb and nichemarket. Start with the first few, and make every listing identical.
Reviews. Hellopeter is where many South Africans go to praise or complain about a business, and complaints there tend to show up in search. It isn’t on Whitespark’s directory list, because it’s a review platform rather than a listing site, but it’s the one I’d check first for any business dealing with the public. Respond to reviews there the way you would on Google.
Lead platforms. For service businesses, sites like Snupit, where customers post a job and get quotes, can also give you a presence AI may find. Judge them on whether they bring real enquiries, not only on visibility.
Language and place names. Use the words your customers use: “geyser”, “braai”, “bond”, “estate agent”. Name suburbs, not just cities. A customer in Durbanville asks about Durbanville, not “the Cape Town metro”. If you serve Afrikaans or isiZulu speaking customers, having key pages in those languages can help you match how they search.
The honest gap. There’s no published study yet showing which sources AI tools cite most for South African local searches. That’s why the method in section 8 matters more here than anywhere else. Your own checks are the best data available.
4. What matters in the United States?
In the US, Yelp carries real weight with AI tools, alongside the Better Business Bureau, Angi, Thumbtack and industry-specific directories. Consolidated “best of” sites like Three Best Rated also appear often. Fake reviews are illegal under the FTC’s 2024 rule, and penalties apply.
The US has the most research, so we can be more specific.
Yelp. In BrightLocal’s 2025 study, Yelp was used as a source in 33% of AI searches, and Perplexity used it in every industry tested. Whatever you think of Yelp, AI uses it.
“Best of” directories. In BrightLocal’s ChatGPT study, Three Best Rated made up almost a quarter of all directory sources. Sites that publish curated lists of top local businesses are worth pursuing, if they’re credible.
Industry directories. BrightLocal found that for dentistry, ChatGPT sourced its answer entirely from dental directories rather than practices’ own websites. Every industry has its own: Healthgrades and Zocdoc for health, Avvo for law, Houzz for home design, and so on.
Home services. Angi, Thumbtack, HomeAdvisor and the Better Business Bureau all appear in AI answers for trades.
Reviews and the law. The Federal Trade Commission’s rule on reviews and testimonials bans fake reviews and incentives tied to a particular sentiment, and allows civil penalties.
5. What matters in the United Kingdom?
In the UK, get listed on established directories like Yell, Thomson Local, 118information, Scoot and FreeIndex, and on the trade and review platforms UK customers trust, like Checkatrade and Trustpilot. Since April 2025, fake and concealed incentivised reviews have been banned under UK law.
Directories. Whitespark’s top UK citation sources include, after the global platforms: 118information, BT’s The Phone Book, Scoot, Thomson Local, Central Index, Yell, Yelp UK, Infobel, FreeIndex, 192.com, TouchLocal, Foursquare, Hotfrog and thebestof. That’s a longer list than South Africa’s, and the first ten are worth the effort.
Trade and review platforms. For trades, Checkatrade, TrustATrader and MyBuilder are where many UK customers look for vetted tradespeople. Trustpilot is widely used for businesses of all kinds. Being present and well reviewed on the right one for your industry gives AI tools something credible to cite.
Reviews and the law. Under the Digital Markets, Competition and Consumers Act, fake reviews and reviews that hide an incentive became banned practices from 6 April 2025. The Competition and Markets Authority has published guidance and has said it is enforcing it.
Language. “Boiler”, “estate agent”, “solicitor”, “builder”, “postcode”. Use UK spellings and terms on UK-facing pages. An American-sounding page is a small signal that you may not be local.
6. What matters in Australia?
In Australia, get listed on Yellow Pages Australia, True Local, StartLocal and Yelp Australia, and on the platforms Australians use to hire and review, like hipages, Oneflare and ProductReview.com.au. Word of Mouth is also on Whitespark’s top list. Fake reviews count as misleading conduct under Australian Consumer Law.
Directories. Whitespark’s top Australian citation sources include, after the global platforms: Yellow Pages Australia, True Local, StartLocal, Factual, Yelp Australia, White Pages Australia, Foursquare, Local.com.au, AussieWeb, dLook and Word of Mouth.
Trade and review platforms. hipages and Oneflare are widely used to find tradespeople. ProductReview.com.au is a popular review site across many categories. As in other markets, pick the ones relevant to your industry.
Reviews and the law. The Australian Competition and Consumer Commission treats fake or misleading reviews as a breach of Australian Consumer Law, and has taken businesses to court over them.
Language. “Tradie”, “sparky”, “arvo”, “suburb”, “postcode”. Use the words your customers type.
7. How do the four markets compare at a glance?
All four share the same global layer. The differences are in the national directories, the review and trade platforms customers trust, the words they use, and the rules on reviews. Almost all published research on AI sources is American, so outside the US, your own testing matters most.
| South Africa | United States | United Kingdom | Australia | |
|---|---|---|---|---|
| Start with these directories | Yellowpages.co.za, Brabys, SAYellow | Yelp, BBB, industry directories | Yell, Thomson Local, 118information | Yellow Pages Australia, True Local, StartLocal |
| Review and trade platforms to check | Hellopeter, Snupit | Yelp, Angi, Thumbtack | Checkatrade, Trustpilot, TrustATrader | hipages, Oneflare, ProductReview.com.au |
| Words customers use | geyser, bond, estate agent | water heater, realtor, zip code | boiler, estate agent, postcode | tradie, sparky, suburb |
| Rules on fake reviews | Google’s policies apply | FTC rule, civil penalties | DMCC Act, since April 2025 | Australian Consumer Law, ACCC |
| Published research on AI sources | Very little. Test your own | The most | Limited. Test your own | Limited. Test your own |
Treat the platform names as a starting point, not a ranking. The right ones for you depend on your industry, and the source check below will show you which ones AI actually uses.
8. How do you find the sources AI trusts in your own market?
Ask AI tools the questions your customers ask, note every source they cite, and look for the ones that keep coming up. Then ask the tools directly which sites matter for your type of business in your area. Build your list from what you find, not from a generic directory list.
This is the most reliable method in any country, and the only one for markets without published research. It builds on the 10-minute self-check.
- Write five customer questions for your business in your area, in your customers’ words.
- Ask them in ChatGPT, Google’s AI Mode and Perplexity, in a private window. Perplexity shows its sources most clearly.
- Record every source cited, especially when competitors are recommended.
- Count the repeats. A site that appears in several answers across different tools is one AI trusts in your market.
- Ask directly. Whitespark’s Darren Shaw suggests asking ChatGPT and Gemini which sites they consider important for your type of business. Treat the answer as a lead to check, not a fact.
- Prioritise: sites AI actually cites first, then industry directories, then the national directory list for your country.
A useful rule: if a site ranks on Google’s first page for your service in your area and AI cites it, you need to be on it.
What to do this week
- Complete the global layer: Google Business Profile, Bing Places, Apple Maps and Facebook, with identical details.

- List the three sites AI cites most for your competitors in your market.
- Claim or create your listing on each of those three.
- Check your market’s top directories from the Whitespark list for your country.
- Review your wording. Replace any foreign terms with the ones your customers use.
- Check your review practices against the rules in your country.
Frequently asked questions
Does ChatGPT work the same way in South Africa as in the US?
The tool is the same, but the sources it finds are different, because the directories, review sites and news outlets are different. Much of the published AI research is American, so test what AI cites for your own searches rather than copying US advice.
Is Yelp worth it outside the US?
It depends on your market and industry. Yelp carries a lot of weight with AI tools in the US. In the UK and Australia, it appears on Whitespark’s top citation lists, so a complete listing is worth having. In South Africa, it’s much less used, and time is better spent on local directories and Hellopeter.
Which AI tool is most used in my country?
ChatGPT is the most widely used standalone AI assistant worldwide, and Google’s AI Overviews reach anyone using Google Search, which dominates search in all four markets. Start with those two. Check Perplexity too, because it shows its sources clearly, which makes it useful for research.
Should I create pages in different languages?
If a meaningful share of your customers search in another language, yes. AI tools match the language of the question. In South Africa, key service pages in Afrikaans or isiZulu can help you appear for those searches. Have them written or checked by a fluent speaker, not machine-translated.
Do fake review laws apply to small businesses?
Yes. The rules in the US, UK and Australia apply to businesses of any size. Beyond the legal risk, Google removes fake reviews and can suspend profiles that break its policies. Ask every customer for an honest review, and offer nothing in return.
How do I know which directories matter for my industry?
Search for your main service in your area and see which directories rank on Google’s first page. Then run the AI source check in this guide. Sites that appear in both are your priority. Industry bodies and trade associations are usually worth joining too.
I serve customers in more than one country. What should I do?
Treat each country as its own market. Use the right domain or country section, local wording and currency, and local contact details where you have them. Build the global layer once, then add each country’s directories and review platforms separately.
