Microsoft Ads Removes Max CPC: What Changes for Advertisers in 2026

Bid caps have quietly powered search advertising for two decades, and one of the last major ones is about to disappear. Starting October 1, Microsoft Ads will remove Max CPC from new campaigns running several of its most popular automated bidding strategies. For any ads agency managing Microsoft Ads accounts, this changes how bids get controlled going forward. At PROHED, a performance marketing agency in Gurgaon, this update is already being folded into client bidding reviews.

What Is Microsoft Ads Removing With the Max CPC Update? 

From October 1, 2026, advertisers will no longer be able to set a Max CPC limit when creating new non-portfolio campaigns that use Target CPA, Target ROAS, Maximize Conversions, Maximize Conversion Value, or Maximize Clicks. The setting will disappear first from the campaign creation screen in the user interface, followed by Microsoft Advertising Editor, though Microsoft has not confirmed that timeline yet. An API update is expected to follow later.

Existing campaigns are not affected immediately. Any campaign created before October 1 that already uses Max CPC will keep the setting, and portfolio bid strategies will continue to support it. Target Impression Share and Enhanced CPC remain untouched too.

What Changes and What Stays the Same

Why Microsoft Is Making This Change

According to Microsoft, Max CPC can quietly work against an advertiser’s own goals. When a bid ceiling sits even slightly above a campaign’s average cost per click, it can block the automated bidding system from reaching auctions it needs to hit a Target CPA or Target ROAS. Microsoft says this mismatch often leads to spend pacing irregularities, where budgets underspend or move unevenly through the day.

Consequently, Microsoft is nudging advertisers toward automated bidding controls, arguing that campaigns using conversion-based targets without Max CPC tend to hit goals more consistently. This mirrors a pattern already playing out industry-wide. Google completed its own sunset of Enhanced CPC in March 2025, and Apple replaced its CPA cap in App Store search campaigns with a target-based system in February 2026.

What This Means for Bidding Campaigns Going Forward

For advertisers who have leaned on Max CPC as a safety net against unexpectedly expensive clicks, this shifts where that control comes from. A few practical implications stand out:

• New campaigns will depend more heavily on daily and campaign-level budgets to manage overall spend.
• Conversion tracking accuracy becomes far more important, since Target CPA and Target ROAS depend entirely on clean data.
• Conversion value rules and seasonality adjustments become the main levers left for shaping automated bidding behavior.
• Portfolio bid strategies may become a more attractive workaround for advertisers who still want a Max CPC option.
• Agencies running advertising on Google Ads and Microsoft Advertising side by side will need to document strategy differences carefully, since the two platforms are no longer aligned on this control.

How to Prepare Before October 1

A short runway remains before the change takes effect, and a few steps can make the transition smoother:

• Audit current campaigns to identify which ones still rely on Max CPC as a primary safeguard.
• Run a controlled experiment removing Max CPC from an existing campaign to see how performance shifts.
• Tighten conversion tracking now, rather than after the new bidding controls are already live.
• Set realistic Target CPA or Target ROAS goals based on at least a few months of historical data.
• Review budget caps, since they become the primary spend control once Max CPC is gone from new campaigns.

Where PROHED Fits Into This

As a full-service ads agency, PROHED manages bidding strategies across both Google advertising and Microsoft Ads for clients spanning D2C, EdTech, FinTech, and B2B sectors. Changes like this one are why campaigns need ongoing management rather than a set-and-forget approach, since automated bidding controls shift regularly.

For brands weighing advertising PPC options between platforms, this update is a reminder that Microsoft Ads and Google Ads are drifting apart in how much manual control they allow. Whether the goal is online marketing through search alone or a blended approach across both networks, having a team that tracks these changes closely matters. This is also where PROHED’s broader digital marketing services, including SEO and social media management, tend to complement paid campaigns.

Conclusion

Microsoft removing Max CPC from new standalone bidding campaigns is part of a larger shift toward automated, goal-based bidding across the industry. Advertisers who prepare now, by tightening conversion data and testing without Max CPC, will likely adjust more smoothly than those who wait until October 1 arrives. As with most platform changes, the businesses that treat this as routine account hygiene tend to come out ahead.

FAQs

1. When does Microsoft Ads remove Max CPC from new campaigns?

The change takes effect on October 1, 2026, and only applies to new campaigns created from that date forward. Anything created earlier keeps its existing Max CPC setting, so there is no need to rush and edit older campaigns.

2. Which bidding strategies lose the Max CPC option?

Target CPA, Target ROAS, Maximize Conversions, Maximize Conversion Value, and Maximize Clicks will no longer support Max CPC on new, non-portfolio Microsoft Ads campaigns. Portfolio bid strategies, Target Impression Share, and Enhanced CPC stay unaffected.

3. Will my existing Microsoft Ads campaigns be affected?

No, campaigns created before October 1 that already use Max CPC will keep the setting for now. Microsoft has not announced a timeline for removing it from older campaigns, so this update is focused on new campaign creation only.

4. What should I use instead of Max CPC?

Microsoft points advertisers toward budgets, Target CPA and Target ROAS goals, conversion value rules, and seasonality adjustments. In practice, this means conversion tracking accuracy matters more than ever, since these tools only work well with clean data behind them.

5. Is this similar to what Google Ads has done with bidding?

Yes, to an extent. Google phased out Enhanced CPC for search and display back in 2025, though it later restored Target CPA and Target ROAS as standalone strategy labels in 2026. Microsoft’s move follows the same broader direction.

6. Should I switch to portfolio bid strategies to keep Max CPC?

It can work as a short-term option, since portfolio strategies retain Max CPC for both new and existing campaigns. That said, portfolio bidding comes with its own structure and reporting differences, so it is worth testing carefully.
