Do you feel advertising platforms provide enough control over your campaign settings?

Google Ads has implemented a software limitation that prevents users from editing their Target ROAS settings during active promotion modes. The system now alerts users that these specific adjustments are disabled while the promotion feature is running.

Why it matters

This change enforces stricter campaign management protocols within the Google Ads interface during active promotional windows. By restricting these edits, the platform seeks to maintain consistency in automated bidding performance throughout a specific sales event.

Google Ads has introduced a new restriction preventing the modification of Target ROAS during promotion mode. The system instead redirects users to an interface option that allows for the adjustment of ROAS tolerance levels.

The players

Google Ads

Google Ads is a comprehensive digital advertising platform that allows businesses to display ads, service offerings, and product listings to web users.

The details

Upon attempting to change Target ROAS settings while a promotion is active, users are met with a system notification explaining the limitation. To ensure campaign continuity, the interface provides a designated path for users to modify ROAS tolerance instead of the primary target.

Market Landscape

This restriction follows a pattern set by Google Ads automated Smart Bidding strategies by further limiting manual overrides to prioritize algorithm stability. The move highlights an industry-wide trend toward platform-governed campaign management that reduces user-driven volatility.

Advertisers should anticipate restricted control over their bidding targets whenever a promotion mode is active in their accounts. Users must plan their bid strategies in advance, as the system will now require reliance on ROAS tolerance adjustments rather than direct Target ROAS edits.

The takeaway

Users should verify their Target ROAS settings before enabling promotion mode to avoid unintended performance outcomes. Adopting the platform-approved tolerance settings is now the primary method for maintaining campaign flexibility during active promotions.
