YouTube needs a watchdog for context, nuance, and good judgment.
YouTube serves ads on thousands of low-quality channels. Filament offers daily blocklists verified by US-based, college-educated analysts to protect your spend and brand safety by cutting off the worst offenders below.
Bad Inventory
AI slop, foreign spam, MFA clickbait, mislabeled kids content. Your ads run alongside channels that erode brand trust, and most tools can’t tell the difference.
Legacy Tools Are Passive
Without custom daily blocklists, you're paying for the worst offenders. Verification platforms flag problems after impressions are served and budgets are spent.
25-50% of Spend Is Wasted
ANA and Adalytics research shows most YouTube inventory fails basic quality checks. Without custom daily blocklists, you’re paying for the worst offenders.
From Raw Inventory to Verified Safe
Filament has analyzed YouTube channels with AI. Then human reviewers verify brand safety and context that algorithms miss. Every day, Filament scans your campaign and unsafe channels get blocked automatically.
