Auto-bidding has become one of the main options for bidding in online advertisements . Advertisers only need to specify high-level objectives and leave the task of bidding to auto-bidders . In this paper, we propose a family of auctions with boosts to improve welfare in auto-bid environments with both return on ad spend constraints and budget constraints . Our empirical results validate our theoretical findings and show that both the welfare and revenue can be improved by selecting the weight of the boosts .
