Microsoft Advertising has added conversion and spend data to Performance Max placement reports, plus landing page reporting with ROAS metrics and impression share visibility. Advertisers can now see and act on where PMax budget is actually being spent.
The biggest complaint about Performance Max has always been "I cannot see where my money is going." Microsoft just answered that.
Microsoft Advertising has added spend and conversion metrics to the Performance Max website publisher URL report. Advertisers can now see not just where their PMax ads appeared, but how much each placement cost and whether it converted.
That is a meaningful step beyond what was available before: impression counts and clicks with no line of sight into spend efficiency.
What changed
The PMax website publisher URL report now includes cost, conversions and conversion revenue alongside the existing impression and click data. Landing page (Final URL) reporting is also now available for PMax campaigns, showing spend, impressions, clicks and ROAS by destination page.
Microsoft also rolled out impression share metrics for Performance Max, including losses by budget and by rank. Asset group-level URL options and tracking templates are now supported.
Spend, conversions and ROAS now visible at placement level in Microsoft PMax campaigns
Why it matters
Performance Max campaigns on both Google and Microsoft have been criticised for opacity. You hand over budget, targeting and creative. The algorithm decides where to spend it. The results come back as a single blended number. If that number is good, great. If not, you have no diagnostic path.
Microsoft's update changes that dynamic. With spend and conversion data at the placement level, advertisers can now identify high-performing placements to scale, low-performing placements to exclude and brand-unsafe inventory to block.
This is particularly relevant for Australian B2B advertisers. Microsoft's audience skews professional and desktop-heavy, which aligns with B2B buying behaviour. PMax on Microsoft with proper placement visibility becomes a genuinely competitive alternative to Google's PMax, where placement transparency remains limited.
