Ask ChatGPT, Gemini and Perplexity the same question about a local service and you'll notice something: they tend to name the same three or four businesses, and when they show sources, the same handful of sites appear again and again. That's not a coincidence. It's how retrieval works, and it's the single most useful thing to understand about AI visibility.
This guide lays out what we see in scans across categories, why those sources dominate, and how to work out which ones matter for your business.
Key takeaways
For any given question, AI assistants read a small number of pages and name the businesses those pages describe. The pages are predictable by category: directories and Google Business Profile for local services, review platforms and comparison articles for software, case-study and vendor directories for agencies. Being present and accurate on those specific pages matters more than almost anything on your own site.
Why a few sources dominate
Every major assistant grounds its answers in retrieved web pages. OpenAI's ChatGPT search uses web results and shows them as citations. Perplexity is citation-first by design. Google's AI features draw on Google's index, per its AI features documentation.
Retrieval systems favour pages that are:
- Aggregators. One page that lists twenty dentists with ratings is more useful to a "best dentist" question than twenty individual clinic homepages.
- Structured. Directories and review sites present the same fields for every business, which makes extraction reliable.
- Authoritative and fresh. Large sites with frequent updates get recrawled often and trusted more.
- Question-shaped. A page titled "Best invoicing apps for freelancers in 2026" matches the question almost verbatim.
Your homepage is rarely any of these. That's why a beautiful site with no third-party presence often loses to a mediocre competitor who's listed everywhere.
What the sources look like by category
The tables below summarise the sources we most often see cited across scans. Exact percentages vary by city and question, so treat these as patterns, not fixed rankings. Your own scan shows the real numbers for your questions.
Local services (clinics, salons, trades, professionals)
| Source type | Typical examples | Why it's cited |
|---|---|---|
| Google Business Profile | Business listings with hours, reviews, categories | Feeds Gemini directly; structured and verified |
| Healthcare and service directories | Practo, Justdial, Sulekha, Yelp, Healthgrades | Aggregated lists with ratings, filtered by area |
| Local news and "best of" articles | City magazines, local news round-ups | Question-shaped, editorially trusted |
| Map and review platforms | Google Maps, Zomato for food, TripAdvisor | Rating counts and recency |
| Your own site | Service pages, location pages | Cited for specific facts once you're already a candidate |
Notice the pattern: the assistant finds you on a directory, then confirms details on your site. If you're not on the directory, the second step never happens.
SaaS and digital products
| Source type | Typical examples | Why it's cited |
|---|---|---|
| Review platforms | G2, Capterra, GetApp, Trustpilot | Category pages with ratings and feature grids |
| Community discussion | Reddit threads, Hacker News, Indie Hackers | Candid comparisons, fresh, question-shaped |
| Comparison and alternatives articles | "X vs Y", "best X for Y", "X alternatives" | Directly match buyer questions |
| Launch and discovery platforms | Product Hunt, AlternativeTo | Structured listings with tags |
| Your docs and pricing pages | Integration docs, pricing page, changelog | Cited for specific facts such as price and integrations |
Reddit deserves a note. Across software questions it's one of the most-cited sources we see, partly because comparison threads are exactly the kind of "which one should I pick" content buyers write. You can't fake presence there, but you can make sure the facts people share are correct by keeping your public pages clear, and you can participate honestly where relevant.
Agencies and consultants
| Source type | Typical examples | Why it's cited |
|---|---|---|
| Vendor directories | Clutch, DesignRush, GoodFirms, Sortlist | Verified reviews, filters by service and location |
| Case studies and client logos | Your own case-study pages, partner directories | Evidence of specific work |
| Partner programmes | HubSpot, Shopify, Webflow partner listings | Third-party validation of a specialism |
| Industry press and awards | Trade publications, award lists | Editorial trust |
How to find your sources
You don't need to guess. Ask the assistants your customers' questions and look at what they cite.
- Write down ten to twenty questions a customer might ask. Mix discovery ("best X in Y"), comparison ("X vs Z"), price ("affordable X") and specific needs ("X with weekend hours", "X that integrates with Stripe").
- Ask each assistant and record which businesses are named and, where shown, which sources are cited.
- Tally the sources. Within twenty questions, three to six sites will account for most citations.
- Check whether you're on each of them, and whether what they say about you is correct.
That tally is your priority list. TangentFlow does this automatically and shows the sources ranked by how often each assistant cites them for your questions, which is what the "competitor reveal" in every scan is.
What to do once you know
Get listed, accurately
Claim or create your listing on each of the top sources. Use the same business name, category, address and phone number everywhere. Inconsistencies are one of the most common reasons an assistant describes a business incorrectly, because it's reconciling conflicting facts from different pages. Google's guidelines for representing your business are a good baseline for how to fill in any directory.
Fill in the fields nobody fills in
Directories have optional fields most businesses skip: services with prices, accessibility, languages spoken, payment methods, integration lists. Those fields are exactly what specific-need questions hinge on. "Dentist in Kochi that accepts insurance" is answered from the insurance field on the directory, not from your homepage.
Earn the comparison and "best of" mentions
For software, the highest-value sources are comparison articles and category round-ups. Some are editorial and some are pay-to-play. Either way, the writers need facts: a clear pricing page, a feature list, screenshots, and a one-paragraph description they can lift. Make that easy to find on a press or "about" page.
For local businesses, the equivalent is local press and "best of" lists. Being a source for a local journalist, sponsoring a community event, or simply having the most complete profile in a category is often what gets a business included.
Keep your own pages consistent with the sources
Once an assistant finds you on a directory, it often reads your site to confirm. If your site says something different, you lose the confirmation. Keep service names, prices and hours identical across your site and your listings.
A note on reviews
Rating counts and recency show up constantly in AI answers ("highly rated, 4.8 with 300+ reviews"). Assistants pull these from directories and Google, not from testimonials on your site. Ask happy customers to review you on the platforms your scan shows are cited most, and respond to reviews so the profile looks active. Don't buy reviews. Platforms remove them, and the mismatch across sources hurts you.
FAQ
Do assistants cite the same sources every time? No. Answers vary between runs and across assistants, which is why measuring over several weeks matters more than a single check. Over twenty questions the dominant sources are stable even when individual answers wobble.
Is being on my own site enough? Rarely, for discovery questions. Your site matters for confirming facts once you're a candidate, and for specific-need and comparison questions where a dedicated page can be retrieved directly.
Which matters more, Google Business Profile or my website? For local discovery questions in Gemini, Google Business Profile. For ChatGPT and Perplexity, directories plus your site. Do both; they reinforce each other.
Can I influence Reddit mentions? Only honestly. Participate where your product is relevant, disclose who you are, and make sure your public facts are right so that people who mention you get them right.
