The May 2026 product update from Microsoft Advertising includes one significant operational change and several smaller upgrades that meaningfully improve campaign management.
The headline addition is the new Import Center, which replaces the scattered import flows for Google and Meta with a single centralised hub.
What changed
The Import Center brings four main capabilities into one place.
Performance recommendations are now generated automatically after each import. Teams no longer need to manually compare imported settings against best practice. Microsoft surfaces the suggested adjustments inline.
Issue resolution is now step by step. Failed imports used to require manual debugging. The new flow guides teams through specific fixes for the most common issues.
Search and filter functionality means teams managing multiple imports can locate specific migrations without scrolling through a chronological list.
The fourth piece is the historical import tracking, which is useful for teams running quarterly Google to Microsoft migrations.
Cross account portfolio bidding
The second meaningful change is cross account portfolio bidding for Search and Shopping. Advertisers managing multiple accounts can now run portfolio bid strategies across the full estate.
For agencies handling client accounts under one Manager Account, this enables better budget allocation and data pooling. Smaller accounts that struggled to generate enough conversion signal for portfolio bidding can now share signal with larger accounts in the same portfolio.
For agencies and freelancers running multiple Microsoft Advertising accounts, this is the kind of operational update that compounds over time. Better bid efficiency across the portfolio means better client outcomes without additional campaign work.
Reporting upgrades
Bid strategy reports now include Average Target ROAS, Average Target CPA, and Average Target impression share at campaign, account, and portfolio levels. That granularity makes it easier to identify where automation is hitting targets and where it is missing.
Custom columns now support all conversion metrics, including segmentation by goal name. For accounts with multiple conversion actions, this means cleaner reporting without exporting raw data into a separate analysis tool.
Data driven attribution rollout
Data driven attribution is rolling out to all Microsoft Advertising customers by the end of May. The model uses machine learning to assign conversion credit based on actual customer journey patterns rather than rule based assumptions.
For advertisers used to last click reporting, the switch will shift how Search, Shopping, and Audience campaigns appear in performance reporting. Microsoft Advertising's contribution in upper funnel touchpoints tends to be undercounted on last click, so the rollout usually changes investment cases for the better.
For advertisers running Microsoft Advertising alongside Google or other paid channels, the data driven attribution rollout is a moment to revisit cross channel budget logic. For brands new to Microsoft Advertising, activation coupons for new accounts extend the runway to build a clean baseline before the new attribution model rolls in.
