Performance Max asset groups and audience signals
Asset groups form the creative clusters of Microsoft Performance Max campaigns. Here is how to structure themes and supply powerful audience signals.
Structuring themed asset groups by product line#
A single Performance Max campaign can contain multiple asset groups. Structuring asset groups around tight commercial themes (e.g., 'Cloud Migration' vs 'Managed Security') ensures that headlines and imagery perfectly match user intent.
As explained in Microsoft Asset Group Guide, 2026, each asset group should direct traffic to a dedicated, highly relevant landing page.
Achieving maximum creative completeness#
Fill every available asset slot to give the AI maximum flexibility across search, native feeds, and video placements:
- 15 Short Headlines (30 chars) and 5 Long Headlines (90 chars).
- 5 Descriptions (90 chars) including value propositions and CTAs.
- Up to 20 High-Resolution Images (1.91:1 landscape and 1:1 square).
- Landscape and Square Brand Logos.
Layering multi-tiered audience signals#
Audience signals teach Microsoft's algorithms where to find your ideal customers during the early ramp phase. Combine first-party Customer Match CRM lists with LinkedIn Company Size and Industry segments as detailed in Microsoft PMax Best Practices, 2026.
Audience signals do not restrict reach; they act as algorithmic launch pads to find similar lookalike buyers.
Evaluating asset-level performance ratings#
Review Asset Performance reports monthly. Replace copy and image assets rated 'Low' with fresh creative variations while preserving 'Good' and 'Best' performing assets.
Consult our Microsoft Ads Hub for asset group templates.

Frequently asked questions#
How many asset groups should I have in a Microsoft PMax campaign?
Most accounts perform best with 3 to 8 tightly themed asset groups clustered around distinct product categories or buyer personas.
Do audience signals limit who can see my Performance Max ads?
No, audience signals guide and accelerate machine learning; the algorithm can still expand beyond the signal if high-probability conversions are identified.
How often should I refresh creative assets in PMax?
Review asset performance ratings monthly, replacing 'Low' performing text and image assets with fresh creative variations.
Can I attach different landing page URLs to different asset groups?
Yes, each asset group has its own Final URL, allowing you to route traffic to specific themed landing pages.
What is the minimum number of images needed for an asset group?
The minimum requirement is one landscape image (1.91:1) and one square image (1:1), but adding 10 to 15 images maximizes algorithmic performance.
