Zefr, DoubleVerify Roll Out AI Brand Safety Tools for Meta Threads

On May 18, 2026, Zefr and DoubleVerify simultaneously expanded AI-driven brand safety controls to Meta’s Threads feed. DoubleVerify introduced pre-screen content-level blocking with 30 new avoidance categories, hourly refreshes, and frame-by-frame video analysis, complementing its October 2025 post-bid measurement. Zefr added pre-bid block lists and always-on measurement under its three-year Meta partnership. The dual launches reduce brand-safety friction, boost advertiser confidence, and support higher ad spend on one of Meta’s fastest-growing surfaces.
