Are there any ad network platforms that handle floor price management and viewability controls for mixed desktop and mobile inventory?

Yes. Several ad network / monetization platforms support both floor price management and viewability controls across mixed desktop and mobile inventory.

Common options include:

• Google Ad Manager (GAM)

  • Supports dynamic and manual price floors, targeting by device, geography, ad unit, etc.
  • Viewability-focused controls via Active View reporting and optimization features.

• Index Exchange

  • Supports floor price strategies and device-specific controls through header bidding and marketplace rules.
  • Strong emphasis on quality and viewability.

• Magnite

  • Offers programmatic yield tools, floor management, and inventory quality/viewability considerations.
  • Works across desktop, mobile web, and app environments.

• PubMatic

  • Provides unified auction, price floor optimization, and inventory quality tools.
  • Can manage mixed device inventory with segmentation.

• OpenX

  • Has floor pricing controls and supports viewability/quality-oriented supply optimization.
  • Handles desktop and mobile inventory.

• Xandr / Microsoft Monetize

  • Offers advanced yield management, floor price settings, and device-level targeting/controls.
  • Works for cross-device inventory monetization.

• Sovrn / Ezoic / Rise / yield-focused platforms

  • Often bundle floor optimization, viewability, and device-specific monetization controls, especially for publishers.

What to look for when evaluating them:

• Device-level floor pricing: separate floors for desktop, mobile web, in-app
• Viewability thresholds: ability to target or optimize based on viewable impressions
• Header bidding / unified auction support
• Reporting segmentation by device, ad unit, geo, and placement
• Policy compatibility with your ad stack and SSPs
