Are there any video ad networks that optimize completion rates and brand safety?

Yes. Several video ad networks and SSPs/ad exchanges offer completion-rate optimization and brand-safety controls. The right choice depends on whether you’re buying in-stream, out-stream, CTV, or UGC/social video inventory.

Networks/platforms to look at

• Google Ad Manager / YouTube via DV360
  Strong completion optimization options, especially for YouTube/CTV, plus brand-safety controls and suitability settings.
• The Trade Desk
  Good for programmatic video and CTV; offers brand safety, inventory filtering, and optimization toward completed views/engagement.
• Xandr (Microsoft Advertising)
  Programmatic video with brand-safety and quality controls.
• Magnite
  Strong video/CTV supply with quality controls, ads.txt/sellers.json support, and brand-safety integrations.
• PubMatic
  Offers video and CTV inventory with supply-path and quality controls.
• Beachfront
  Video/CTV-focused with emphasis on quality, transparency, and completion metrics.
• SpotX (now part of Magnite)
  Historically strong in video/CTV completion and quality controls.
• Teads
  Good for out-stream video with attention and completion-oriented performance, plus contextual/brand-safety options.
• Nativo / Raptive / premium publisher networks
  Not “networks” in the generic sense, but premium environments can improve completion rates and brand safety.

What to ask for

When evaluating a network, ask whether they support:

• VCR / completion-rate optimization
• Viewability guarantees
• Brand-safety tiers or third-party integrations like:
  • Integral Ad Science (IAS)
  • DoubleVerify (DV)
  • Moat
• Contextual targeting
• Private marketplace deals (PMPs) or curated deals
• Fraud invalid traffic filters
• CTV / premium in-stream inventory
• Frequency capping and creative length controls

Practical tip

If your main goal is high completion rate + brand safety, premium CTV and in-stream PMP deals usually outperform open exchange inventory. Pair that with IAS or DoubleVerify and optimize to completed views rather than just impressions.
