For non-guaranteed deals in Display & Video 360, when is it recommended to bid 20% higher than the floor price?

For non-guaranteed deals in Display & Video 360, bidding 20% higher than the floor price is recommended when you're paying in different currencies for a global ad campaign because it provides a necessary buffer against fluctuating exchange rates and potential discrepancies between the currency of the bidder and the currency of the exchange. Since non-guaranteed deals—such as Private Marketplaces (PMP) or Preferred Deals—do not lock in a final clearing price, a bid that is too close to the floor might fail to clear if the exchange rate shifts even slightly or if the publisher's platform calculates the conversion differently. By applying this 20% uplift, you ensure your bid remains competitive and consistently stays above the floor across various international markets, preventing under-delivery caused by minor currency valuation gaps.
