Why Microsoft’s Bid Strategy Report Update Matters for PPC Teams

In May 2026, Microsoft Advertising announced new metrics for the Bid Strategy Report as part of its monthly product roundup. The update arrived together with the new Import Center, cross-account portfolio bidding, seasonality adjustments, Data-Driven Attribution, and expanded custom columns.

The new Bid Strategy Report metrics include Avg. Target ROAS, Avg. Target CPA, and Avg. Target impression share. Microsoft says these metrics are available at the campaign, account, and portfolio levels, which makes the report more useful for advertisers managing automated bidding across several campaigns or accounts.

Automated Bidding Gets a Clearer Diagnostic Layer

Bid Strategy Report is not a new campaign type, ad format, or targeting option. It is a reporting view for understanding how automated bid strategies are performing. The May 2026 update adds more visibility into the targets that the system is actually optimizing toward.

This matters because automated bidding is often difficult to explain after the fact. A campaign may be using a target CPA or target ROAS setting, but performance can shift because of conversion delays, budget limits, target changes, auction movement, or portfolio-level optimization. The new metrics help advertisers see the average target that applied during the reporting period, not only the final performance outcome.

In practice, the report gives teams a better way to answer questions like: did ROAS decline because the target changed, because conversion delay is still unfolding, or because the strategy is actually underperforming? That distinction is important for anyone managing Microsoft Ads with automated bidding.

Why Average Targets Are More Useful Than Static Settings

A static target does not always tell the full story. If a team adjusts Target CPA or Target ROAS during the month, the campaign’s current setting may not explain the performance that happened earlier in the period. Avg. Target CPA and Avg. Target ROAS make that history easier to interpret.

The same logic applies to Target impression share. A campaign may appear to be missing its current target, but the average target across the period may show that the goal changed or that the campaign was optimizing under a different constraint for part of the reporting window.

For agencies, this is especially useful in client reporting. Instead of explaining automated bidding only through final CPA, ROAS, spend, and conversion volume, teams can show how the target itself moved over time and whether the strategy had enough time and data to respond.

Where It Fits in Microsoft’s Bidding Roadmap

The update also fits a broader Microsoft Advertising shift toward simpler bidding setup and more centralized automation. Earlier in 2026, Search Engine Land reported that Microsoft was simplifying automated bidding setup by folding familiar targets such as Target CPA and Target ROAS into broader automated strategies rather than treating them as fully separate campaign settings.

That creates a need for better reporting. If bidding options become more streamlined and more automated, advertisers need clearer diagnostics to understand what the system is doing. The Bid Strategy Report update helps close that gap.

Microsoft’s own documentation on budget and bid strategies explains that Target CPA and Target ROAS strategies are designed to optimize bids in real time toward a 30-day average goal. The new average target metrics make that optimization logic easier to monitor inside reporting.

A Practical Update, Not a Flashy One

The market reaction has been positive but practical. Search Engine Land described the new metrics as part of a broader update for bidding, reporting, and import workflows. Search Engine Roundtable also highlighted the same three metrics: Avg. Target ROAS, Avg. Target CPA, and Avg. Target impression share.

This is not the kind of update that changes the visual experience for the end user. It does not create a new AI ad placement, a new shopping surface, or a new audience signal. But for advertisers managing performance, it can be more useful than many larger announcements because it improves the day-to-day ability to diagnose automated bidding.

The sentiment is mostly positive because the update adds transparency. Advertisers are willing to use automated bidding, but they need to understand why performance changes. Reports that connect target settings, campaign outcomes, and portfolio-level behavior make automation easier to trust.

Bottom Line for Performance Teams

The Bid Strategy Report update is a small but important improvement for Microsoft Ads performance management. It gives advertisers more context around the targets used by automated bidding and helps separate true performance problems from target changes, learning periods, and conversion delays.

Compared with Microsoft’s larger AI updates, this one is less about the future of search and more about operating campaigns today. It follows the broader market trend: as platforms automate more bidding decisions, they need to give advertisers better reporting around the inputs and constraints that shape those decisions.

The practical takeaway is simple. Teams should use the updated Bid Strategy Report during weekly and monthly reviews, especially when analyzing Target CPA, Target ROAS, Target impression share, and portfolio strategies. Automated bidding works best when advertisers can see not only the final result, but also the target path the system was following.
