# Microsoft Advertising is removing Max CPC from new standalone automated campaigns

From October 1, new non-portfolio Microsoft Advertising campaigns using several automated bidding strategies will lose the Max CPC bid ceiling, shifting another auction-level cost control into targets, budgets or portfolio strategies.

Microsoft Advertising is taking Max CPC out of new standalone automated campaigns from October 1. Existing capped campaigns and portfolio strategies retain the control for now, but advertisers creating new campaigns will need to rely more heavily on conversion targets, budgets and portfolio bidding.

## What changed

Microsoft Advertising has notified advertisers that, from October 1, 2026, Max CPC will no longer be available when creating new non-portfolio campaigns using standalone automated bidding strategies. Reporting from Search Engine Land and Search Engine Journal, along with a reproduced Microsoft advertiser email and confirmation from Microsoft Ads Liaison Navah Hopkins, says the affected paths include Maximize Conversions, Maximize Conversion Value and Maximize Clicks; target-based variants such as Target CPA and Target ROAS are part of the same automated-bidding control model where the cap is being removed at standalone campaign creation. Existing campaigns that already have a Max CPC can retain it for now, while portfolio bid strategies, Enhanced CPC and Target Impression Share continue to support a ceiling. Microsoft says a hard cap can conflict with an automated strategy’s performance goal and disrupt spend pacing.

## Why it matters

A Max CPC is a hard auction-level guardrail: it limits what the platform may pay for one click even when an automated strategy wants to bid more. Removing that control from new standalone campaigns changes risk management for advertisers that use tCPA, tROAS or maximize-style bidding but still want protection from unusually expensive clicks. The replacement controls are not equivalent. Budgets limit aggregate spend, and CPA/ROAS targets describe desired average outcomes rather than a maximum single-click price. Teams that still require a hard ceiling may need to use a portfolio strategy or another retained bidding path, and should test whether that structural workaround changes campaign behavior or reporting.

## The cutoff applies when new standalone campaigns are created

The advertiser notice says Max CPC will no longer be available from October 1 when creating new non-portfolio campaigns. Search Engine Land and Search Engine Journal report that existing campaigns with a Max CPC will keep the setting, so the immediate change is not a forced migration of the installed base. That distinction matters for agencies planning Q4 launches or recreating campaigns from templates.

## Portfolio strategies keep the hard ceiling

Microsoft Ads Liaison Navah Hopkins said portfolio bid strategies, Enhanced CPC and Target Impression Share will continue to support Max CPC. For advertisers that need a hard per-click limit, a portfolio strategy becomes the clearest retained route after October 1. Teams should not assume that moving a campaign into a portfolio is operationally identical to its current standalone configuration; targets, learning history and governance should be tested.

## Targets and budgets do not replace a per-click cap

Microsoft’s own current documentation describes Max CPC as an optional control that makes sure the platform does not pay more than a specified amount for an individual click under automated strategies. By contrast, Target CPA and Target ROAS optimize toward averages over time, while campaign budgets constrain aggregate spend. Removing Max CPC therefore changes the type of risk being controlled, not simply the location of the same setting.

## Microsoft’s rationale is optimization freedom

The company says Max CPC can give its bidding system conflicting instructions when an advertiser simultaneously asks it to hit a CPA or ROAS target and prevents bids above a fixed ceiling. Microsoft argues that removing the cap can make it easier for automated bidding to optimize toward the stated business goal. Whether that improves advertiser outcomes depends on conversion quality, auction volatility and the value distribution of clicks; the claim should be tested at account level rather than assumed.

## The API and Editor migration path is not fully published

The initial change is being described for campaign creation in the Microsoft Advertising interface. Specialist reporting says Editor support will change later and an API update is expected, but Microsoft has not published a public migration document specifying exact API-version behavior or a forced-conversion path for existing capped campaigns. Microsoft’s current Learn documentation still describes Max CPC fields for automated strategies, so integration owners should watch for documentation and schema updates before October 1.

## Key details

- The change takes effect October 1, 2026.
- New non-portfolio campaigns using affected standalone automated bidding strategies will no longer expose a Max CPC control.
- Existing campaigns that already use Max CPC are reported to retain it for now.
- Portfolio bid strategies continue to support Max CPC, according to Microsoft Ads Liaison Navah Hopkins.
- Enhanced CPC and Target Impression Share also retain Max CPC.
- Microsoft says hard CPC caps can conflict with automated CPA/ROAS and maximize-style optimization goals.
- Microsoft’s current public API documentation still describes Max CPC controls; the detailed API/Editor migration timetable has not yet been publicly documented.

## Builder takeaways

- Audit campaign templates and launch playbooks before October 1 so teams know which new Microsoft Ads campaigns currently depend on a Max CPC safeguard.
- If a hard per-click ceiling is a business requirement, test a portfolio bid strategy before the cutoff rather than discovering the constraint during a live campaign launch.
- Do not treat a daily budget or Target CPA/ROAS as equivalent to Max CPC; they manage aggregate or average outcomes and can still permit individual high-cost clicks.
- Strengthen conversion tracking and value signals before relying more heavily on uncapped automated bidding, because the bidding system has less useful guidance when conversion data is noisy or sparse.
- Record pre-change CPC distributions, outlier click costs, CPA/ROAS and conversion quality so you can evaluate whether uncapped new campaigns materially change auction economics.
- If you provision campaigns through the API, Editor or bulk workflows, monitor Microsoft’s documentation for field/schema changes and do not assume UI timing maps one-to-one onto integration timing.

## What to watch

- A public Microsoft Advertising help or API announcement documenting the October 1 change directly.
- The exact Microsoft Advertising Editor and API dates for removing Max CPC from affected new campaigns.
- Whether existing standalone campaigns are eventually migrated or allowed to keep Max CPC indefinitely.
- Whether advertisers report materially higher CPC outliers, better conversion performance or both after the cap is removed.
- Whether Microsoft narrows or expands the portfolio-strategy exception.

## Uncertainties

- The core change is supported by a Microsoft advertiser notification reproduced by specialist publications and confirmation attributed to Microsoft Ads Liaison Navah Hopkins, but Microsoft has not yet published an easily discoverable public help-page announcement for the October 1 cutoff.
- Specialist reports differ slightly in how they enumerate target-based strategy labels, while agreeing that the change applies to new non-portfolio automated campaigns and that portfolio strategies retain the cap.
- Microsoft has not publicly specified a forced-migration date for existing capped campaigns or the exact API-version behavior after October 1.
