PR Agency Bifurcation

PR Agency Bifurcation describes the structural divergence of the public relations industry into two distinct trajectories: traditional agencies built on retainer models and human media relationships that are declining, and agencies oriented toward AI visibility, data-driven placement, and Machine Relations that are growing. This is not a cyclical downturn — it is a permanent industry split driven by the same forces reshaping search and discovery.

The Evidence

The data is unambiguous. Edelman, the world's largest independent PR firm, posted an 8.1% revenue decline — its third consecutive year of contraction. Meanwhile, Publicis Groupe, which invested heavily in AI and data capabilities, grew 4-5% over the same period. The pattern extends beyond these two firms. Agencies clinging to traditional media relations, press release distribution, and impressions-based measurement are shrinking. Agencies integrating AI visibility strategy, citation tracking, and performance-based models are expanding.

The split is not about firm size. It is about which side of the AI visibility divide an agency operates on. Traditional PR agencies sell activities — pitches sent, press releases distributed, media lists maintained. The market is repricing those activities as commodities because AI has made them insufficient to drive the outcome clients actually need: appearing in AI-generated recommendations.

What Drives the Split

Three structural changes are forcing bifurcation:

• Discovery shift — Buyers increasingly find brands through AI engines, not media coverage scans. Traditional PR placements that do not translate into AI citations deliver declining value.
• Measurement evolution — CMOs and CFOs demand attribution to pipeline and revenue. Retainer agencies selling "awareness" without citation data or AI visibility metrics cannot justify spend.
• Zero-click search dominance — With 69% of searches producing no clicks, the traffic-based value of traditional media coverage has structurally declined.

Where This Leads

The bifurcation will continue to widen. Agencies that build Machine Relations capabilities — earned authority strategy, entity signal optimization, AI citation monitoring, GEO — will capture the growing share of communications budgets shifting toward AI visibility outcomes. Agencies that remain in the traditional model will compete on price for a shrinking pool of clients still measuring PR by clip counts and ad value equivalency.

The PR industry is not dying. It is splitting. The category emerging on the growth side is Machine Relations — and the agencies that recognized this shift earliest hold a structural advantage that compounds with every quarter the bifurcation deepens.
