Do you know which YouTube channels your ads are actually running on?

  • Blocked before the first impression
  • Works with Performance Max & Demand Gen
  • One toggle. Fully automatic.

Are your ads showing up on
YouTube channels you'd never choose?

AI-driven campaigns like Performance Max and Demand Gen automatically push your ads across YouTube.
Tracking which channels they land on by hand gets harder every year.

"We didn't find out our ads were on inappropriate channels until it was too late."

Brand damage from channels you never chose

With AI-driven delivery, you can't pick the YouTube channels your ads appear on ahead of time. When your ad plays during or next to a video that clashes with your brand, it can hurt your brand image. And manually reviewing every placement just isn't realistic for a marketing team.

"We can't keep track of every channel our ads end up on."

Too many placements to track and manage by hand

With AI-driven delivery, placements change daily and spread across thousands of channels. Combing through reports for inappropriate placements and updating exclusion lists by hand is a heavy, never-ending burden for your team.

With AI-driven delivery on the rise,
automatic channel-level exclusion is no longer optional

A fast-growing video ad market, and Spider Labs research showing how little control advertisers have over where AI-driven campaigns deliver.

The video ad market is set to pass $6.6 billion (¥1 trillion) in 2026, and automatic delivery to YouTube through Performance Max and Demand Gen will only keep growing. At the same time, the more AI takes over delivery, the less visibility marketers have into where their ads actually run, and the less control. The YouTube placements that Performance Max and Demand Gen select automatically are no exception: inappropriate, off-brand channels slip through unnoticed. That's why automatic, channel-level exclusion before your ads ever reach a risky channel matters now.

How it differs from the existing placement exclusion

* The existing placement exclusion is available on the Elite plan and above.

The existing placement exclusion covers website placements and excludes them at the domain level. Channel Blocklist adds YouTube: channels classified into brand-risk categories are excluded at the channel level. Both sit in the same Google Ads placement exclusion list.
