Admiral is the leading adblock revenue recovery platform for publishers and the pioneer of Visitor Relationship Management (VRM). Trusted by thousands of publishers and backed by more than a decade of recovery expertise, Admiral has helped publishers recover more than $100 million in adblock revenue across trillions of protected requests. Admiral pioneered Full Spectrum Adblock Recovery to address today's fragmented adblock landscape—from browser extensions and privacy browsers to VPNs, DNS and network-level blocking, dark traffic, and more resistant blockers. Instead of relying on a single recovery technique, Full Spectrum combines four core approaches: Full-Stack Recovery, Reinsertion, Server-side Protection, and Alternative Value Exchange. Publishers can use these approaches independently or together through Combo Recovery to maximize total adblock revenue. Full-Stack Recovery restores the publisher's complete advertising stack when possible, while reinsertion—including Acceptable Ads and proxy reinsertion—adds recovery opportunities for other blocker environments. Server-side protection extends coverage to more resistant blockers, while alternative value exchanges can convert adblocked visitors through subscriptions, registrations, email acquisition, donations, and other outcomes. Admiral's VRM platform provides the intelligence and orchestration behind Full Spectrum Recovery, enabling publishers to detect and measure blocked traffic, segment audiences, target recovery experiences, sequence offers, test approaches, and continuously optimize performance. Beyond adblock recovery, Admiral helps publishers maximize revenue recovery and revenue growth through subscriptions and paywalls, consent management, first-party data, registrations, email and social audience growth, donations, journey shaping, marketing automation, and AI-powered Visitor Copilot. One audience. Multiple recovery paths. More revenue recovered.
