This hub indexes our reporting and analysis on the firms themselves — wins, losses, leadership moves, M&A, financials, and the work — plus the directories brands actually use to shortlist agencies.
Sector specialists run the cycle that matters in their vertical — regulators, analysts, trade press, and now the AI engines that synthesize all of it for buyers.
Region still matters: it dictates the media list, the regulators, the holidays, and the language of the answer engines.
The full alphabetical index of individual agency profiles lives at /pr-agency-profiles-directory — every firm we cover, by name, with links to their EPR coverage, leadership, sector focus, and notable work.
For two decades, brands hired PR firms to influence what reporters wrote and what showed up on page one of Google. In 2026, that''s necessary but no longer sufficient. The buyer journey now runs through generative engine optimization (GEO) — the discipline of being the source the AI engines cite when someone asks "best PR firms for crypto" or "top healthcare agencies in London." Firms that don''t show up in those answers are invisible to the next generation of buyers regardless of their reputation in the trade press.
Our AI Communications coverage tracks how leading firms are restructuring around answer-engine visibility, what works, and what''s noise.
The full chronological feed of agency news, leadership moves, account changes, M&A, and analysis is below.
