When working on a non-guaranteed deal in Display & Video 360, in what situation would you recommend bidding 20% higher than the floor price?

Bidding 20% higher than the floor price on a non-guaranteed deal is recommended when dealing with global campaigns and multiple currencies. This buffer helps account for potential currency exchange rate fluctuations between the time the bid is placed and when the impression is served, ensuring your bid remains competitive and doesn't fall below the floor price due to currency shifts. Frequency management is handled through line item settings, not by adjusting bid price relative to the floor. Guaranteeing a fixed number of impressions is characteristic of a guaranteed deal, not a non-guaranteed one. Working across multiple publishers within a deal doesn't inherently necessitate a higher bid buffer for currency reasons; the currency issue is specific to international transactions.
