Microsoft Advertising Removes Max CPC from New Campaigns in 2026: What Advertisers Need to Know

What Is the Max CPC Change in Microsoft Advertising?

The key change is that Microsoft Advertising will no longer allow advertisers to set a maximum cost-per-click (Max CPC) limit on new campaigns that use standalone automated bidding strategies, effective October 1, 2026. This applies specifically to campaigns using Maximize Conversions, Maximize Conversion Value, or Maximize Clicks bidding without a portfolio strategy.

According to a report from Search Engine Land, Microsoft Advertising notified advertisers via email and through a LinkedIn post from Microsoft Ads Liaison Navah Hopkins. The change is being framed as a move to prevent Max CPC limits from interfering with automated bidding algorithms, which can cause spend pacing issues and suboptimal auction performance.

Existing campaigns that already have a Max CPC set will continue to respect that cap. The change only affects new campaigns created after October 1, 2026. Advertisers who want to retain the option for future campaigns will need to use portfolio bidding strategies, Target Impression Share bidding, or enhanced CPC (eCPC) — all of which will retain the Max CPC setting.

Which Bidding Strategies Are Affected?

The removal applies specifically to three standalone automated bidding strategies when used outside of a portfolio:

• Maximize Conversions: This strategy automatically sets bids to get the most conversions within your budget. Previously, advertisers could set a Max CPC ceiling as a safeguard. After October 1, that ceiling will no longer be available for new campaigns.
• Maximize Conversion Value: This strategy optimizes for conversion value (such as revenue) rather than raw conversion count. The Max CPC option will also be removed for new standalone campaigns.
• Maximize Clicks: This strategy aims to get the most clicks within your daily budget. The Max CPC limit will be removed for new standalone campaigns as well.

The change was confirmed by multiple industry publications, including PPC Land and Search Engine Roundtable. The reporting indicates that Microsoft's rationale is that Max CPC caps can contradict the goals of automated bidding, leading to inefficiencies.

Which Strategies Retain Max CPC?

Not all hope is lost for advertisers who depend on Max CPC as a control mechanism. Several bidding options will continue to offer the setting:

Bidding Strategy	Max CPC Available After Oct 1?	Notes
Portfolio bidding strategies	Yes	Includes Maximize Conversions, Maximize Conversion Value, and Maximize Clicks when nested inside a portfolio
Target Impression Share	Yes	Retains Max CPC cap option
Enhanced CPC (eCPC)	Yes	Manual bidding with eCPC enabled still allows a Max CPC limit
Standalone Maximize Conversions	No	For new campaigns only
Standalone Maximize Conversion Value	No	For new campaigns only
Standalone Maximize Clicks	No	For new campaigns only

According to Search Engine Journal, portfolio bidding strategies remain a viable workaround for advertisers who want to retain the Max CPC guardrail while using automated bidding. A portfolio bid strategy applies the same bidding method across multiple campaigns, which can also simplify management.

Why Is Microsoft Removing Max CPC?

Microsoft's stated reason is that Max CPC limits can interfere with the performance of automated bidding algorithms. When an advertiser sets a low Max CPC, the algorithm may be unable to bid competitively for high-value auctions, resulting in missed conversions. Conversely, a high Max CPC may not provide enough protection to make the advertiser feel comfortable.

The company argues that removing the cap encourages advertisers to rely on conversion-based targets — such as Target CPA (cost per acquisition) or Target ROAS (return on ad spend) — which give the algorithm full flexibility to bid appropriately for each auction. This approach aligns with Google Ads' long-standing recommendation to avoid setting bid caps with automated bidding, though Google still allows Max CPC limits on some automated strategies.

In a LinkedIn post cited by PPC Land, Navah Hopkins explained that Max CPC caps can create spend pacing issues, causing campaigns to underdeliver or overshoot budget targets. The change is intended to improve overall campaign performance and simplify the bidding interface.

Industry Reactions: Advertisers Express Frustration

The announcement has generated significant discussion among PPC professionals. Some advertisers view the change as a loss of control that could increase risk for campaigns with tight budgets or sensitive verticals.

Freelance Google Ads manager Joey Bidner, quoted in the Search Engine Land report, noted that the ability to set a native Max CPC cap was a differentiator for Microsoft Ads compared to Google Ads. In Google Ads, if you want a Max CPC limit on an automated strategy, you typically need to use portfolio bidding or third-party tools. Microsoft's removal of this feature brings it closer to Google's model, which some advertisers see as a step backward.

Other commenters on industry forums, such as SEOFORUM, expressed concern that smaller advertisers who rely on Max CPC as a safety net may be forced into less comfortable bidding arrangements. The change could also affect agencies that manage multiple client accounts with varying risk tolerances.

However, some advertisers welcome the change, arguing that Max CPC limits often hinder performance and that Microsoft's push toward fully automated bidding is the right direction for most campaigns. The debate highlights the ongoing tension between advertiser control and algorithmic optimization in paid search.

How Does This Compare to Google Ads?

Google Ads took a different path. Google allows Max CPC limits on its automated bidding strategies, such as Maximize Conversions and Target CPA, but strongly recommends against using them. Google's documentation warns that setting a bid cap can prevent the algorithm from achieving its target, similar to Microsoft's stated concern.

The key difference is that Microsoft is outright removing the option for new standalone campaigns, while Google leaves it in place but discourages its use. This makes Microsoft's move more aggressive and arguably more aligned with the long-term direction of automated bidding across the industry.

Advertisers who switch between Microsoft Advertising and Google Ads will need to adjust their workflows. On Microsoft, portfolio bidding becomes the only native way to retain a Max CPC cap with automated strategies. On Google, advertisers can still set a bid cap on standalone campaigns, though they are advised not to.

What Should Advertisers Do Now?

With the October 1 deadline approaching, advertisers have several options:

1. Switch to portfolio bidding strategies: This is the most straightforward workaround. Create a portfolio bid strategy that uses Maximize Conversions, Maximize Conversion Value, or Maximize Clicks, and then apply a Max CPC limit at the portfolio level. Existing campaigns can be migrated into the portfolio before creating new ones.

2. Adopt target-based bidding: Instead of relying on a Max CPC cap, move to Target CPA or Target ROAS. These strategies give the algorithm clear performance goals without the need for a manual ceiling. Many advertisers find that target-based bidding outperforms capped automated bidding over time.

3. Use enhanced CPC (eCPC): If you prefer manual bidding but want some automation, eCPC automatically adjusts your manual bids up or down based on conversion likelihood. eCPC retains the Max CPC option, giving you a middle ground.

4. Test Target Impression Share: For campaigns focused on visibility rather than conversions, Target Impression Share bidding retains the Max CPC cap. This is useful for brand awareness campaigns.

5. Export and review existing campaigns: Before October 1, audit your existing campaigns that use standalone automated bidding with a Max CPC. Consider whether to convert them to portfolio strategies or switch to target-based bidding to prepare for future campaign creation.

A Broader Industry Trend: The Shift to Full Automation

Microsoft's move is part of a larger industry trend toward removing manual controls from automated bidding. Both Google and Microsoft have increasingly pushed advertisers to trust their algorithms, arguing that machine learning models can optimize bids more effectively than humans, especially at scale.

This trend has accelerated with the introduction of AI-powered tools like Google's Performance Max and Microsoft's Audience Campaigns. These campaign types offer even less manual control, requiring advertisers to provide assets and conversion goals while the platform handles bidding, targeting, and creative optimization.

For advertisers who value control, the removal of Max CPC is a reminder to stay adaptable. Those who rely on manual controls may need to invest in third-party bid management platforms or develop more sophisticated portfolio strategies to replicate the safeguards they are losing.

The Timeline: What Happens Next?

• August 20, 2026: Microsoft Advertising notifies advertisers via email and LinkedIn. Industry publications break the news.
• October 1, 2026: The change takes effect. New campaigns using standalone Maximize Conversions, Maximize Conversion Value, or Maximize Clicks cannot set a Max CPC limit.
• Ongoing: Existing campaigns with Max CPC settings are unaffected. Portfolio bidding, Target Impression Share, and eCPC retain the option.

Advertisers should plan their migration before October 1 to avoid disruption when creating new campaigns after the deadline.

Bottom Line: Prepare for the Change

Microsoft Advertising's decision to remove Max CPC from new standalone automated bidding campaigns is a significant change that will impact how advertisers configure their paid search campaigns. While existing campaigns are safe, anyone planning new campaigns after October 1 must adapt.

Portfolio bidding strategies offer the most direct workaround for those who want to keep the Max CPC safety net. However, Microsoft's long-term trajectory is clearly toward fully automated, target-based bidding. Advertisers who embrace this direction will find it easier to stay ahead of future changes.
