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

What Is Changing: Microsoft Advertising Removes Max CPC From New Campaigns

The key change is that Microsoft Advertising will no longer allow advertisers to set a Max CPC (maximum cost-per-click) limit on new non-portfolio campaigns that use standalone Maximize Conversions, Maximize Conversion Value, or Maximize Clicks bidding strategies. This policy takes effect on October 1, 2026, and applies to campaigns created after that date. Existing campaigns using Max CPC with these strategies will remain unaffected for now, as will portfolio campaigns and manual CPC campaigns.

According to multiple reports Search Engine Land, Microsoft Advertising sent email notifications in August 2026 and Microsoft Ads Liaison Navah Hopkins confirmed the change publicly. The move is part of a broader push toward automated, conversion-based bidding and away from manual cost controls that can interfere with machine learning algorithms.

Effective Date and Scope

The change is effective October 1, 2026. Here is a breakdown of which campaign types are affected:

Campaign Type	Max CPC Allowed After Oct 1, 2026?	Notes
New standalone Maximize Conversions campaign	No	Must use target CPA or conversion value
New standalone Maximize Conversion Value campaign	No	Must use target ROAS
New standalone Maximize Clicks campaign	No	Must use target CPA or budget
Portfolio campaigns (any bidding strategy)	Yes	Still allowed
Existing campaigns using these strategies	Yes (for now)	Not affected immediately
Manual CPC, Enhanced CPC, Target CPA, Target ROAS	Yes	Separate strategies not affected

This table clarifies that the restriction applies specifically to new campaigns that are not part of a portfolio and use one of the three standalone automated bidding strategies. Portfolio campaigns, which allow multiple campaigns to share a bid strategy and often include Max CPC limits, retain the option PPC Land.

Why Microsoft Is Removing Max CPC

Microsoft Advertising’s stated rationale is that Max CPC limits can interfere with automated bidding algorithms. When advertisers set a low Max CPC, the algorithm cannot effectively bid for high-value auctions, reducing the system’s ability to maximize conversions or conversion value. By removing the ceiling, Microsoft aims to give its machine learning models full freedom to optimize bids in real time.

This aligns with a broader industry trend. Google Ads has similarly evolved its automated bidding over the years, gradually phasing out manual controls for Smart Bidding strategies. Microsoft’s move mimics that trajectory, emphasizing target CPA (cost-per-acquisition) and target ROAS (return on ad spend) as the primary levers instead of a per-click cap Marketers Index.

The removal of Max CPC is also a signal that Microsoft wants advertisers to rely more on budget-level controls and conversion goals rather than granular per-click limits. This approach works best when campaigns have sufficient conversion data and when advertisers are comfortable trusting the algorithm.

Advertiser Reactions and Concerns

The announcement has drawn mixed reactions from the PPC community. Many advertisers appreciate the safety net that Max CPC provides, especially when scaling campaigns or testing new products. Without a per-click limit, there is concern that bids could spike temporarily, leading to higher costs before the algorithm stabilizes.

On the Search Engine Roundtable, commenters noted that the change could penalize advertisers who lack historical conversion data SERoundtable. Start-ups, new campaign launches, or seasonal promotions might struggle with fully automated bidding because the algorithm needs data to learn. Some advertisers are considering moving to portfolio bidding as a workaround, since portfolio campaigns still allow Max CPC.

Others view the change as inevitable. As one commenter on PPC Land said, "Microsoft is following Google's lead. We need to adapt our strategies toward target CPA and ROAS anyway." The shift reflects a growing acceptance that AI-driven bidding outperforms manual controls when given enough freedom.

Alternative Bidding Strategies Available After October 1

Advertisers who lose the ability to set Max CPC on new campaigns have several alternatives:

• Target CPA: Set a target cost per conversion. The algorithm will aim to hit that average while maximizing conversions.
• Target ROAS: Set a target return on ad spend. Useful for revenue-driven campaigns.
• Enhanced CPC: Manual bidding with automatic adjustments toward conversions (still allowed and independent of this change).
• Portfolio bidding: Combine multiple campaigns under a shared bid strategy that can include Max CPC limits. This remains a valid option for advertisers who want a per-click ceiling.
• Budget-based controls: Use campaign budgets and daily spend limits instead of per-click caps.

According to Search Engine Journal, Microsoft recommends that advertisers transition to target CPA or target ROAS for new campaigns, and use portfolio strategies if they absolutely need Max CPC. The change does not affect manual CPC or Enhanced CPC campaigns, so advertisers who prefer hands-on control can use those strategies instead.

Broader Industry Trend: The Shift to AI-Powered Bidding

The removal of Max CPC is not an isolated decision. It reflects a larger industry movement toward fully automated, AI-driven bid management. Both Google and Microsoft have invested heavily in machine learning models that optimize bids across billions of signals—device, location, time of day, audience, and more. Manual ceilings like Max CPC conflict with these models because they impose a hard cap that the algorithm cannot exceed, even when the traffic is highly valuable.

This trend also connects to the rise of AI-generated content and advertising creatives. As more advertisers adopt AI tools for product videos, ad copy, and landing pages, the bidding side of the funnel is also being automated. The goal is end-to-end optimization: AI creates the ad, AI sets the bid, and AI measures the conversion. Microsoft’s policy change removes one of the last manual controls in that chain.

How to Prepare Your Campaigns for the Change

Advertisers should take the following steps before October 1, 2026:

1. Audit existing campaigns that use standalone Maximize Conversions, Maximize Conversion Value, or Maximize Clicks with a Max CPC limit. Decide whether to leave them running (they are unaffected for now) or migrate to portfolio bidding.
2. Test target CPA or target ROAS on existing campaigns to gather data before launching new ones. Use the performance history to set realistic targets.
3. Consider portfolio bidding if you need a per-click ceiling. Create a portfolio bid strategy that includes a Max CPC limit and assign new campaigns to it.
4. Review conversion tracking to ensure accurate data flows into Microsoft Advertising. Automated bidding relies on quality signal input.
5. Monitor budgets closely during the first few weeks of new automated campaigns. Without a Max CPC safety net, daily spend could fluctuate more.

The SEO Forum discussion highlights that many advertisers plan to keep existing campaigns intact but will use portfolio setups for any new launches. Others are simply accepting the change and focusing on target ROAS as their primary KPI.

What This Means for the Future of PPC

Microsoft Advertising’s decision underscores a permanent shift in search advertising: manual controls are giving way to machine learning. While Max CPC offered a sense of control, it also capped performance. The algorithm can now bid freely up to the budget limit, making it possible to capture high-value clicks that previously would have been excluded.

For advertisers who rely on AI-driven bidding across other platforms like Google Ads, this change is familiar. Microsoft is now harmonizing its features with Google’s approach, making cross-platform bidding strategies simpler to manage. The biggest challenge will be for advertisers with sparse conversion data or low budgets, who may need to invest in conversion tracking or use portfolio strategies as a bridge.

The removal of Max CPC is a notable milestone in the evolution of paid search. As AI continues to improve, such manual levers will likely disappear entirely. Advertisers who adapt now by embracing target CPA, target ROAS, and portfolio bidding will be better positioned for the next wave of automation.

Conclusion

Microsoft Advertising’s removal of Max CPC from new standalone campaigns taking effect October 1, 2026, is a significant change that requires advertisers to rethink their bidding strategies. While the loss of a per-click safety net may be unsettling, the shift aligns with industry-wide adoption of AI-powered bid management. By leveraging alternatives like target CPA, target ROAS, and portfolio bidding, advertisers can continue to control costs without sacrificing performance.
