UGC beats review sites in ChatGPT citations across 35K SaaS prompts
Most SaaS marketing budgets fund digital PR (targeting publishers) and review campaigns (targeting G2, Capterra, and peers). That is where the attention goes. That is not where ChatGPT is pulling its citations from.
Kevin Indig ran an analysis of roughly 35,000 ChatGPT citation URLs captured in Profound, covering US only, ChatGPT only, during December 2025. Each citation was classified as a review platform, UGC platform, publisher, or vendor domain. The study covered four SaaS buyer journey stages: discovery, exploration, evaluation, and focused evaluation.
What the data shows
Strip out vendor domains and UGC platforms hold 17.1% of cited domains, more than 4x publishers at 4.0%. Review platforms sit in between, peaking at evaluation and falling off after that.
The more surprising finding is how stable UGC is across every stage. Review platform share swings from 7.4% at discovery to 13.2% at evaluation, a 5.8-point range. UGC barely moves: 17.8%, 18.2%, 15.1%, 17.2%, a 3.1-point range across all four stages. It shows up when buyers are learning what they need and again when they are comparing two finalists.
Platform concentration inside the UGC bucket
The 17% UGC floor is not evenly distributed. Wikipedia, Reddit, and LinkedIn account for 99% of UGC citations in the sample. Wikipedia alone runs 10.1 to 14.0 points of that 17-point floor depending on journey stage, making it the single largest third-party source in the dataset at most stages.
That concentration creates a portfolio problem. Wikipedia is the largest and the least actionable for most operators. Reddit is the most volatile: it dropped 11.7% in AI visibility and 10.9% in AI mentions in the 28 days to June 8, 2026, then recovered sharply three weeks later. LinkedIn gained 43.3% SEO visibility in the 28 days to June 29, 2026. These platforms do not move together and are not interchangeable.
What this means for AI visibility
On July 7, 2026, Google introduced platform properties in Search Console reporting clicks, impressions, CTR, and queries for Instagram, TikTok, X, and YouTube. Reddit and LinkedIn, the two platforms doing the most work in AI citation sets, are not included. The new feature also measures classic Google Search and Discover visibility, not AI answers, so teams that treat it as an AI visibility signal will be measuring the wrong surface with real numbers.
The study also found that 91% of citations appear in only one AI engine, so ChatGPT results should not be read as a proxy for all AI search.
Eight actions the analysis supports
- Run your highest-intent prompts and record which UGC domains appear in citations. The composition is local to your topic. In some categories it will be Reddit and YouTube. In others it is Stack Exchange or a trade forum.
- Put named people in the places that matter. A named author with a byline appears to outperform the same content under a brand account. LinkedIn’s own testing pointed the same direction. A community treats a person as a participant and a logo as an advertiser.
- Answer the questions your support queue already sees on repeat. Ticket logs, sales call transcripts, and in-app search queries hold the exact phrasing buyers use. A question already sitting on a forum is a ready opportunity.
- Pull real third-party review quotes into the top of your highest-cited pages. According to separate research cited in the analysis, 44.2% of citations come from the first 30% of a page. Run it as a test with a control set rather than assuming it will work.
- Track UGC-sourced citations as one number and platform composition as a second. The first tells you whether the floor is holding. The second tells you where to move next quarter.
- Mine communities for questions and terminology. Extract the words buyers use to describe your category, features, and competitors, then use that language in your prompts and copy.
- Correct stale threads that misrepresent your product. A 2023 thread claiming you lack a feature you shipped last year stays retrievable. Reply in-thread with a dated correction and a link to the change. Set alerts on brand plus category terms using tools like F5Bot for Reddit and Hacker News, or Syften for Discord and Slack coverage.
- Give customers something worth posting. Early access to data, a free tool, a number they can quote. That is as close to ownership of UGC as the category allows.
The analysis warns against buying reviews or astroturfing threads. The framing is: show up where the answers are already being assembled, not manufacture the appearance of presence.
