Invisible in ChatGPT? What Singapore Businesses Should Change So AI Assistants Recommend Them
By Jon Ng, Founder, Novatise · 4 min read · 31 October 2026
A Singapore clinic, shop or renovation contractor can sit on page one of Google and still never be named when a customer asks ChatGPT, "Who's good near Tampines?" The assistant gives three or four names. If yours isn't one of them, the customer never sees you.
We covered why this happens in You Can Rank #1 on Google and Still Never Be Named by ChatGPT, and the technical side in Optimizing for AI Search (GEO & LLMO). This piece is the Singapore version: the local test to run, the local sources that matter, and what we look at when we audit a business here.
Step 1: Run the test the way Singaporeans actually ask
Generic questions give generic answers. Customers here ask with places and local habits built in, so your test should too.
- Use neighbourhoods and MRT stations, not just "Singapore". Try "GP clinic near Bishan MRT", "aircon servicing in Punggol" or "phone repair at Bugis".
- Ask in the languages your customers use. If a good share of your customers search in Chinese, Malay or Tamil, ask the same question in that language too.
- Ask the questions people ask before they buy. For example "Which renovation contractors in Singapore are HDB-registered?", "Which clinics near Jurong East are open on Sunday?" or "Where can I buy a phone case in Singapore today?"
- Ask ChatGPT, Gemini, Claude and Grok, each in a fresh chat. Write down every business named, the order, and what each assistant says when you ask, "Why did you choose these?"
The "why" answers are the useful part. They tell you which sources the assistant trusted: a review site, a directory, a news article or your own website.
Step 2: Fix what AI assistants look for in Singapore
1. Put your business facts on your site in plain text, and add schema
Your registered business name, UEN, full address with the six-digit postal code, nearest MRT, phone, WhatsApp number, opening hours (including public holidays) and the areas you serve should all be readable as text, not only in an image or a PDF. Then add LocalBusiness schema (or a more specific type such as MedicalClinic or HomeAndConstructionBusiness) with the same details, so search engines and AI systems read the same facts you show customers.
2. Show the credentials that customers here check
Singapore customers often look for proof of registration or accreditation before they call. If you hold relevant ones, such as HDB's Directory of Renovation Contractors, BCA registration, CaseTrust accreditation or an MOH licence, state them clearly on your site and make sure the official listing matches your business name exactly. Only list what you really hold.
3. Collect real reviews where Singaporeans read them
Google reviews matter most for most local businesses, but also check the platforms your customers use, such as Facebook, marketplace stores or industry review sites. Ask happy customers, reply to every review, and never buy or fake one. Clinics should check MOH's advertising rules before quoting patient feedback on their own website.
4. Earn mentions on local sites
Assistants trust a business more when other sources agree with it. For Singapore that can mean local "best of" lists and guides, neighbourhood and community pages, trade associations, supplier or partner pages, and coverage in local media. One honest mention on a well-known Singapore site usually counts for more than dozens of low-quality directory entries.
5. Make every listing match
Check your Google Business Profile, Apple Maps, Facebook page, marketplace stores and directories. The name, address, postal code, phone number and hours should match your website exactly. Close old branch listings, and update listings when you move units, which happens often with shophouse and mall tenants.
6. Write pages that answer real customer questions
Short, factual pages work best: price ranges in SGD, what's included, how long a job takes, whether you accept CHAS, Medisave or PayNow (if you do), which areas you cover and how to book. If customers ask it on WhatsApp, it probably deserves a page.
7. Re-test on a schedule
AI answers change as models and sources update. Re-run the same questions every two or three months, using the same wording, and keep a simple spreadsheet so you can see whether you're being named more often.
What we check in a Novatise AI-search audit
When we audit a Singapore business, we work through the same list:
- The assistant test. We ask ChatGPT, Gemini, Claude and Grok your real customer questions, by neighbourhood and in the languages that matter to you, and record who gets named and why.
- Your website facts and schema. Is everything an assistant needs readable, accurate and marked up?
- Credentials and trust signals. Are your registrations and accreditations visible, and do official listings match?
- Reviews. Where they are, how recent they are and whether you reply.
- Mentions and listings. Which local sources mention you, which mention your competitors, and where your details don't match.
- Content gaps. Which customer questions have no clear answer on your site.
You get a short, ranked list of what to fix first, so you're not guessing.
