ArcSpan Integrates First‑id — Persistent Cookieless Identity for Publisher Monetisation

Context

ArcSpan announced a native integration with First‑id, a deterministic identity solution used by over 35,000 media and advertiser sites worldwide. The move gives publishers a persistent cookieless identity layer, potentially improving ad targeting and revenue attribution in a post‑cookie era. Publisher monetisation teams should evaluate how this integration fits into their existing identity strategy.
