Microsoft Advertising Removes Max CPC From New Campaigns

Will your Microsoft Advertising campaigns lose the Max CPC option this fall? Starting Oct. 1, Microsoft Advertising removes Max CPC from new standalone bidding campaigns that use Maximize Conversions, Maximize Conversion Value or Maximize Clicks, and this matters now because many advertisers set up new campaigns ahead of the holiday season.

What Microsoft Advertising Removes Max CPC From New Standalone Bidding Campaigns Means for You

Starting Oct. 1, you won’t be able to add a Max CPC limit when you create new campaigns using standalone Maximize Conversions, Maximize Conversion Value or Maximize Clicks bidding. Max CPC is the highest amount you allow Microsoft to bid on your behalf for a single click. Campaigns you built before Oct. 1 keep their current Max CPC settings. Target Impression Share, eCPC and portfolio bidding strategies also keep support for Max CPC. The change applies only to new standalone campaigns using the three strategies named above.

Why Microsoft Says It Removes Max CPC From New Standalone Bidding Campaigns

Microsoft says Max CPC limits can override the performance goals you set and can cause spend pacing problems, meaning your budget gets spent unevenly across the day or month. The company states that advertisers using target CPA or target ROAS bidding generally have an easier time hitting their goals than advertisers who rely on Max CPC. Microsoft Advertising Product Liaison Navah Hopkins confirmed these details. Microsoft has not shared specific performance numbers to back this claim, so treat it as the company’s stated position rather than an independently confirmed result.

How the Change Affects Existing Campaigns Right Now

Your existing campaigns won’t lose Max CPC on Oct. 1. Microsoft confirmed there is no automatic migration for campaigns already running with Max CPC in place. The restriction applies only when you build a new standalone campaign using Maximize Conversions, Maximize Conversion Value or Maximize Clicks after Oct. 1. Microsoft says it will share more updates about the future of Max CPC later, though it has not given a date for that announcement.

What to Use Instead of Max CPC

Microsoft wants you to control campaigns through budgets, target CPA, target ROAS, conversion value rules and seasonality adjustments instead of a CPC cap. Hopkins describes target CPA and target ROAS as the main levers for controlling volume and value going forward. She also noted that Microsoft Advertising can let campaigns outperform their target CPA or target ROAS even when a budget limit applies. If certain conversions matter more to your business than others, Microsoft recommends setting conversion value rules so the bidding system weighs them correctly. Because target CPA and target ROAS bidding lean entirely on the conversion signals you feed them, any gaps or inaccuracies in that tracking data will directly undermine performance once Max CPC is no longer an option. A platform like Measuremate is built for exactly this kind of check, helping you confirm that your conversion tracking and attribution data are solid before you hand more control over to automated bidding.

How to Prepare Before Oct. 1

Hopkins recommends running optimization experiments that remove Max CPC from your existing campaigns before the deadline hits. An optimization experiment lets you test a change on part of your traffic while comparing it against your current setup. This gives you real performance data before the option disappears from new standalone campaigns. Hopkins flagged this as especially useful heading into the holiday season, when many advertisers rebuild or relaunch campaigns and could run into the new restriction without warning.

Test removing Max CPC on a current campaign now, before Oct. 1, so you know what to expect when you can no longer add it to new standalone campaigns. Watch for Microsoft’s promised follow-up on the future of Max CPC, since that update could affect how you plan campaigns beyond this fall. Pay close attention to your conversion data quality, because your results under target CPA or target ROAS bidding depend directly on it. Since your results under target CPA or target ROAS bidding depend directly on clean conversion data, a tool like Measuremate can help you audit and validate your GA4 and tracking setup before you lean harder on automated bidding this fall.
