For a decade, marketing budgets moved away from PR and toward search and paid media. AI search is reversing that. The engines your buyers now ask for recommendations build their answers mostly from earned media, and study after study points the same way.

A growing share of B2B research now starts in an AI chat instead of a search box. The buyer asks a question, the engine reads a set of sources and writes an answer. It doesn't show ten blue links. It recommends.
Those engines need sources they can trust, and they treat a company's own website as marketing. Journalism and other third-party coverage read as evidence. In Muck Rack's latest study, journalism alone accounted for 27% of cited links, and earned media overall has held between 82% and 89% across all three editions of the research.
Search rankings and AI citations are drifting apart. Moz found that most citations in Google's AI Mode come from pages that don't rank in the organic results for the same query. Ahrefs found that what tracks AI Overview visibility most closely is how often a brand is mentioned across the web, not how many backlinks it has.
That's a PR signal, not an SEO one. Being written about, often and credibly, is what puts a company into the answer.
Muck Rack's data shows only a 2% overlap between the journalists PR teams pitch and the sources AI cites. Traditional PR chases prestige outlets. AI engines draw from a wider mix: trade publications, niche reporters, data-rich explainers and the sources that cover a category in depth.
So PR matters more than it has in years, but the old playbook leaves most of the value on the table. The target list has to change.
A note on sources: several of these studies come from PR and media-monitoring companies, which have an interest in the result. Independent SEO research from Ahrefs and Moz points the same way, but read each with that in mind.
