Promotion Mode documentation sets out its bidding and budget limits

What changed

The open beta supports eligible Search and Performance Max campaigns, with exclusions for shared budgets and portfolio strategies. The documented sale window is three to fourteen days. This is a documentation follow-up to an existing feature; review eligibility and setup lead time before scheduling a promotion.

The important distinction is between a temporary sale setting and a permanent change to the campaign’s commercial objective. A lower Target ROAS permits a different balance between conversion value and advertising cost. It does not guarantee extra profitable orders, and the optional budget increase creates a separate spending decision. Teams should evaluate both against the actual promotion margin rather than treating the feature name as an instruction to increase spend.

Before scheduling, identify the affected campaigns, their bid strategies and budget arrangements. Shared budgets and portfolio strategies are excluded in the documented scope. Check that the planned promotion fits the three-to-fourteen-day window and that the account meets the current setup requirements. A sale calendar alone does not establish eligibility.

Record the original target and budget, the promotion dates and the approved temporary values. After the sale, confirm that the intended settings have returned and review results after allowing for conversion delay. Separate the effect of the offer, stock availability and creative from the effect of the bidding configuration.
