Microsoft PMax Website Publisher URL report adds conversion and spend metrics
Microsoft Advertising has added conversion and spend metrics to the Performance Max Website Publisher URL report, addressing a transparency gap that had limited the report's usefulness. Navah Hopkins has flagged the change and notes the practical use case: advertisers can now identify which publisher placements are converting and at what spend level, then build Audience Ads campaigns specifically targeting the winning placements.

What changed
The value lies in using Performance Max as a discovery layer for high-converting placements, then graduating them into more controlled campaign types. Without spending data, the report only showed where ads ran. Conversion and spend data show where ads ran profitably.
Why it matters for advertisers
For you, this means Microsoft Performance Max becomes more useful as a placement-discovery tool rather than only a reach play. Worth a fortnightly review of the new Publisher URL report for accounts with meaningful Microsoft PMax spend, with the goal of identifying placements that justify a dedicated Audience Ads buy.
