94% of the links that AI chatbots cite come from non-paid sources. That's the headline finding from Muck Rack's Generative Pulse research, which analyzed over one million links cited by ChatGPT, Claude, Gemini, and Perplexity between July and December 2025.
The practical takeaway for anyone creating content: if you want AI to reference your work, traditional media coverage and high-quality editorial content matter far more than paid placements or ads.
Earned Media Runs the Show
Of all citations tracked, 82% came from earned media - coverage you didn't pay for, like news articles, reviews, and editorial mentions. Journalism specifically accounted for 20-30% of all citations, and that number jumped to nearly 50% for time-sensitive queries where users asked about recent events.
The most-cited outlets read like a who's-who of established publications: Reuters, The Guardian, Forbes, Nature, The Verge, U.S. News and World Report, Yahoo Finance, Investopedia, and NerdWallet. But niche-specific outlets also showed up consistently when users asked industry-specific questions. AI isn't just defaulting to the biggest names - it pulls from relevant trade publications and specialized sources too.
Recency Bias Is Real
Half of all citations came from articles published within the previous 11 months. Only 4% pointed to content from the prior week, which suggests AI models favor relatively recent content but aren't chasing breaking news the way search engines do.
This has direct implications for content strategy. Evergreen content still has a shelf life in AI responses, but it's longer than the typical SEO decay curve. Publishing solid, well-sourced content on a regular cadence matters more than racing to be first.
The PR Disconnect
One finding stands out for marketing teams: there's only a 2% overlap between the journalists that PR professionals pitch most often on Muck Rack and the journalists whose work AI actually cites. That's a massive gap. Teams are spending effort building relationships with writers whose content rarely appears in AI-generated answers, while the writers AI does cite are largely being ignored.
Press releases also saw a surprising surge. Citations of press releases increased 5x between July and December 2025. The ones that got cited shared specific traits: they contained twice as many statistics, 30% more action verbs, 2.5x as many bullet points, and 30% more objective sentences compared to press releases that AI ignored.
In other words, AI rewards press releases that read like data-rich fact sheets, not marketing fluff.
What This Means for Content Creators
The study confirms something many content marketers have suspected: AI-generated answers are essentially a new distribution channel, and it favors the same qualities that good journalism does - specificity, authority, recency, and factual density.
For small businesses and freelancers trying to get mentioned in AI responses, the path runs through earned media and genuinely useful content rather than paid placement. Getting covered by relevant niche publications may now be as valuable for AI visibility as it is for traditional SEO.
