How does ChatGPT cite brands?

ChatGPT cites brands by grounding its answers in web search and leaning heavily on community and editorial sources, with Reddit as its single most-referenced external domain. Across the Indian brands Cited tracks, 16% of every external citation ChatGPT made went to Reddit alone, more than five times its next source and roughly double the concentration any other engine shows on its own top source. The pattern that sets ChatGPT apart is how much weight it puts on forums, editorial coverage, and third-party discussion when it decides which brands to name.

How Cited measures this

Cited tracks how a set of brands are cited across five AI engines on the same prompts, which makes the differences between engines directly comparable. The brands are Indian companies across D2C, retail, finance, edtech, and SaaS, measured on each brand's own prompt set run identically on every engine over a 90-day window.

The figures below count external citations only, meaning every cited source other than the brand's own domain, and express each engine's top source as a share of that engine's external citations. Concentration is what the measure captures: how much of an engine's outside sourcing funnels into one place.

ChatGPT is the outlier. No other engine concentrates anything close to a sixth of its outside sourcing on a single domain, and Gemini sits at the opposite end, spreading citations thinly across a long tail of marketplaces and retailers.

Reddit is ChatGPT's top external source

The finding that matters most for brands: across every brand Cited measured, Reddit was ChatGPT's most-cited external domain, ahead of marketplaces, editorial publications, and specialist review sites. Its nearest rival source took under 3% of ChatGPT's external citations, against Reddit's 16%. After Reddit, ChatGPT drew on category and lifestyle editorial (the beauty, finance, or tech press relevant to each brand), large marketplaces, and specialist review sites.

This is a real behavioural signal. ChatGPT uses web search to ground answers to comparative questions, and community forums carry the first-hand, opinion-rich discussion that those questions call for. A brand that is discussed favourably and accurately in the communities where its category lives is feeding the exact source ChatGPT reaches for first.

What this means for being cited by ChatGPT

Two things follow.

First, your own pages still matter. A brand's own domain is among the sources ChatGPT reaches for on most brand-relevant prompts, so clear, well-structured, crawlable pages remain the foundation. If ChatGPT cannot reach your content, it cannot cite it.

Second, and less obvious, your off-site presence is doing more work with ChatGPT than with any Google engine. Because Reddit and editorial coverage rank so highly in what ChatGPT cites, being genuinely present and well-regarded in third-party discussion is not a nice-to-have. It is central to how ChatGPT decides which brands to name. This is the same off-site pattern that underpins brand authority in AI search, and it is more pronounced on ChatGPT than on Gemini, which leans on commerce sources instead.

The useful contrast is with the other engines. Gemini is the most commerce-anchored, spreading its sourcing across marketplaces and retailers; Google AI Overviews leans on social and video platforms. ChatGPT is distinctive for how much it rewards community and editorial presence.
