An answer is built from the pages it cites
When ChatGPT searches the web before answering, it reads a handful of pages and writes its answer from them. OpenAI says ChatGPT search uses third-party search providers and content from partners, and the answer shows links to its sources.
That makes the cited pages the most practical thing you can study. If an answer about your category names three rival brands and not you, the pages it cited are where it got that list. Change what those pages say about you, or become one of those pages, and you change what the answer has to work with.
The hard part is that “which sites does ChatGPT cite?” has no single answer. It depends on the topic, the market, the wording of the question, and how the answers were collected.
What a large US study found
Ahrefs, an SEO tool company, publishes a running list of the domains ChatGPT cites most, built from a broad set of US queries across all topics (the page we read was updated on 2 September 2026, with September 2026 data). In that dataset:
- Reddit was the most-cited domain, with 810,887 of its pages cited.
- Wikipedia was second, with 129,667 of its pages cited.
- Consumer Reports and Forbes were also near the top.
That’s a big, useful dataset, and it’s why so much AI advice says “get on Reddit and Wikipedia”. But it describes US questions on every topic, from car repairs to legal questions. Your buyers are asking narrower questions.
What we found for Indian brands
Citationly’s own recordings tell a different story for the categories we’ve measured. Across three Citationly runs, for an insurer and two packaged-food brands in India:
- 222 answers in all, from OpenAI’s model through its API with web search on, recorded between late September and early October 2026, for commercial buying questions.
- Brands’ own websites were the most-cited sites: both the website of the brand each run was for and its rivals’ websites.
- For insurance, the regulator’s website was also among the most cited.
- For one food brand, quick-commerce sites appeared in some answers.
- Reddit was cited in 2 of those 222 answers, and YouTube in 1.
We don’t know which cause explains the difference from the US study. It could be API answers versus the ChatGPT app, the Indian market, the buying-question style, or the categories themselves. We don’t claim any one of them. What we can say is that, for these categories, “go and post on Reddit” was not supported by the answers we recorded.
The lesson: check your own category
Generic AI-visibility checklists assume every category cites the same sites. The two datasets above show they don’t. Before you spend a rupee on getting mentioned somewhere, find out where the answers in your category actually look.
You can do a rough version yourself:
- Write 10–20 questions a buyer in your category might ask, from “what should I look for in a…” to “which brand is best for…”.
- Ask each one in ChatGPT with search on, more than once (here’s why answers change).
- Open the sources on each answer and write down every website cited.
- Count, for each website, how many answers cited it. Pay most attention to the answers that didn’t name you: those sources are where the answer looked instead.
How to get onto each kind of site
Once you know your category’s sources, the next step depends on what kind of site each one is.
| Kind of site the answers cite | What to do |
|---|---|
| Your own website | Make sure the page that sells each product answers the buyer’s question in the buyer’s own words. See how to write a product page AI answers can quote. |
| Rival brands’ websites | Read the pages that were cited. Note what they explain that your equivalent page doesn’t: specifications, comparisons, who it’s for. Cover the same ground, honestly, on your own page. |
| Regulators and official bodies | You can’t buy a place here. Check that your registration, product or licence details are complete and correct wherever the regulator publishes them. |
| Marketplaces and quick-commerce sites | Check that your products are listed, named the way buyers search, and described accurately and completely. |
| Review sites, comparison sites and publications | Make sure they have accurate facts about you. Offer information, samples or data to editors who cover your category. Ask for corrections where they’re wrong. |
| Forums and video sites | Act here only if your category’s answers actually cite them, and take part as a genuine voice, not with planted posts. |
Two technical checks come first for your own site. Make sure OpenAI’s search crawler can read it: OpenAI says sites that block OAI-SearchBot will not be shown in ChatGPT search answers. And make sure your pages show their text without JavaScript. Our free checker tests both in seconds.
What not to do
- Don’t buy or fake mentions. Google’s own guide to generative AI features says chasing inauthentic “mentions” isn’t as helpful as it might seem. Planted posts and paid fake reviews also put your brand’s name next to exactly the kind of content answers are built to filter out.
- Don’t follow a checklist written for another market. A source that dominates US answers may never appear in yours.
- Don’t judge from one answer. One answer’s sources are a sample of one. Count across many answers.
Then measure again
After you’ve acted, ask the same questions again and compare which sites are cited and whether you’re named. Keep the questions identical, because comparing runs that asked different questions tells you nothing. And remember that two runs show a difference, not proof of what caused it.
How Citationly helps
Every Citationly report has a section called “Where the answers looked instead”: the websites cited in the answers that left you out, strongest evidence first, each one opening to the answers that cited it. Book a demo to see one, or start with the free checker.
