Google Ads has expanded the period for performance-based cost adjustments within its Demand Gen campaigns to 60 days. This update replaces the previous three-week window for tCPA and tROAS campaigns.
Why it matters
The change aims to keep actual campaign performance metrics more closely aligned with set targets throughout the learning phase. By extending this window, the system provides more room for campaigns to stabilize against predicted conversion levels.
The automated cost adjustment feature now spans 60 days, significantly longer than the prior 3-week maximum. Adjustments remain active until the campaign hits its cost limit or duration, with activations occurring within 5 days of startup.
The players
Google Ads
Google Ads is a digital advertising platform that allows businesses to display ads across Google's search engine and partner networks.
The details
The system automatically lowers campaign costs when conversions drop below expected levels during the initial learning phase. These final costs appear directly in reporting without separate notifications or distinct line items.
Timeline
November 2025: The beta program launched for Demand Gen tCPA campaigns.
October 16, 2026: Google updated its help documentation to reflect the new 60-day window.
October 19, 2026: News of the policy update was published.
Market Landscape
This move reflects a broader trend of platforms automating campaign management to reduce the manual oversight required by advertisers. By extending these algorithmic safeguards, Google aims to increase advertiser retention in its competitive ad tech ecosystem.
Advertisers should monitor their campaign spend closely, as cost adjustments will now be reflected in final amounts rather than as separate line items. This change may impact budget planning for those utilizing tCPA or tROAS bidding strategies over the 60-day period.
The takeaway
Advertisers using Demand Gen should prepare for automated shifts that persist well into the campaign lifecycle. Monitoring your account for consistent performance data is essential now that these adjustments can remain active for up to two months.
