Microsoft Ads Max CPC Removed Oct 1
Microsoft Ads Max CPC is going away for new campaigns. Starting October 1, 2026, the Max CPC bid limit will no longer be available when you create a new non-portfolio Maximize Conversions, Maximize Conversion Value, or Maximize Clicks campaign, confirmed across [ppc.land](https://ppc.land/microsoft-advertising-drops-max-cpc-from-new-campaigns-on-october-1/), Search Engine Land, and [Search Engine Roundtable's](https://www.seroundtable.com/microsoft-advertising-max-cpc-sunset-41917.html) August-September 2026 coverage. Existing campaigns keep it. New ones will not have the option at all, and there is no popup in the account telling you it is gone.
What actually changes on October 1
When you build a new non-portfolio campaign using Maximize Conversions, Maximize Conversion Value, or Maximize Clicks after October 1, the Max CPC field simply will not be there. Today that field lets you set a ceiling, the platform will not bid above it no matter what its own algorithm wants. After the change, bidding on those new campaigns is fully automated with no advertiser-set cap.
| Campaign type | Before Oct 1 | After Oct 1 |
|---|---|---|
| New non-portfolio Maximize Conversions / Conversion Value / Clicks | Max CPC bid limit available | Max CPC option removed, fully automated bidding only |
| Existing campaigns created before Oct 1 | Max CPC bid limit available | Unchanged, keeps Max CPC |
| Portfolio bid strategies | Not the primary lever anyway | Unaffected by this change |
Who is actually affected
This only hits new campaigns, not existing ones. If you or your agency are spinning up a new Microsoft Ads campaign on or after October 1, and it uses one of those three bid strategies without a portfolio wrapper, you will not see Max CPC as an option. Anything already running before that date keeps its current bid limit untouched, this is not a retroactive migration.
Why this keeps happening
This is not an isolated change, it is part of a broader pattern across ad platforms: manual bid controls that founders set once during initial setup and never revisit are quietly being narrowed or removed in favor of the platform's own automated bidding. Each individual change is defensible on its own, the platform's algorithm usually does perform better with fewer constraints. But nobody sends a notice explaining which lever just disappeared from the account, or who is expected to notice.
The pattern is consistent across platforms: each change is a small accuracy improvement to the algorithm. The sum, over enough of these, is fewer manual levers for the person actually running the account, and no single notification telling them which one just went away.
Checklist before you build a new campaign
| Check | Why it matters |
|---|---|
| Confirm your bid strategy before creating a new campaign | Max CPC will not be selectable for new Maximize Conversions/Value/Clicks campaigns after Oct 1 |
| Set a realistic daily budget floor first | There is no manual bid ceiling left to catch a spike on a new campaign |
| Watch spend closely in the first week | Fully automated bidding without a cap needs a tighter budget leash while it learns |
| Ask your agency directly whether this touches your account | Only new campaigns built after Oct 1 are affected, not your existing ones |
What still works exactly the same
Every campaign already live before October 1 keeps its Max CPC setting exactly as configured, this change does not touch it. Portfolio bid strategies are unaffected too. You can still edit budgets, targeting, and creative on existing campaigns without triggering any of this, the change is scoped narrowly to how new non-portfolio campaigns get created going forward.
Who should own this
The actual risk here is not the change itself, it is not knowing it happened until a new campaign is already live and bidding without a cap. That is exactly the gap a fractional marketing director is supposed to close, someone who is actually in the ad accounts often enough to catch a platform change before it costs money, covered under our Paid Media work.
FREQUENTLY ASKED
What changes with Microsoft Ads Max CPC on October 1, 2026?
New non-portfolio Maximize Conversions, Maximize Conversion Value, and Maximize Clicks campaigns will no longer have the option to set a Max CPC bid limit. Bidding on those new campaigns becomes fully automated with no advertiser-set cap.
Does this affect my existing Microsoft Ads campaigns?
No. Only new non-portfolio campaigns created on or after October 1, 2026 are affected. Campaigns already running before that date keep their current Max CPC setting unchanged.
What should I do before October 1 if I am launching a new campaign?
Confirm your bid strategy before creating the campaign, set a realistic daily budget floor since there is no manual bid ceiling anymore, and watch spend closely in the first week while automated bidding learns.
Is this the same as other automated bidding changes on ad platforms?
It follows the same broader pattern, ad platforms steadily narrowing or removing manual bid controls in favor of their own automated bidding, though the specifics, timeline, and platform here are Microsoft Ads-specific.
