Ad Quality: Enhanced bidder blocks (Limited Beta)

Release date: January 6, 2026
Product: Microsoft Monetize – Ad Quality: Enhanced bidder blocks

Overview

We’ve introduced enhancements to Ad Quality controls for Bidder Blocks, now available in Closed Beta. These updates improve visibility, hierarchy, and control when managing trust settings across bidders, members, and buyer seats.

What’s new

Unified hierarchy and improved visibility

• The Ad Quality UI now presents a clear hierarchy: Bidder → Member → Seat, making it easier to understand how trust settings are applied.
• You can set trust levels at the bidder level, with the ability to override settings at the member or seat level for more granular control.
• Across network and publisher rules, the system continues to apply the most restrictive (conservative) setting when conflicting rules exist.

Support for buyer seat IDs

• The UI now indicates whether a bidder has fully transitioned, partially transitioned, or not transitioned to buyer seat IDs.
• This visibility helps you apply blocks at the correct level—bidder, member, or seat—for more precise enforcement.

Best practices

• For global enforcement, apply blocks at the bidder level.
• For targeted control, use member-level or seat-level overrides as needed.
• Review your existing settings to ensure blocks are applied at the appropriate level.
• Use the Seller Bid Error Report to validate that blocks are enforced as expected.

Important considerations

• If you previously configured bidder overrides during the Closed Beta, those settings were applied only to the bidder’s default member.
• If a bidder has non-default members, you must reapply the bidder trust level at the bidder level to ensure the setting applies to all members under that bidder.
