AI总结:

本文提出一种在第一价格拍卖中设置底价的模型,已在雅虎实施,显著提升展示广告和视频广告的年化增量收入,分别达1.3%和2.5%。

摘要:

底价(也称为保留价格)帮助发布商提高其广告位的预期收入,广告位通常通过拍卖出售。底价定义为卖方(可以是发布商或广告交易平台)愿意接受库存机会的最低出价。在本文中,我们提出了一个在第一价格拍卖中设置底价的模型,并讨论了其在雅虎网站上实施的影响。该模型捕捉了在线广告行业的重要特征。例如,一些投标人限制广告交易平台如何处理投标人的数据,从而影响设置保留价格的模型选择。我们的解决方案促使投标人改变其投标行为,以响应投标请求中包含的底价,帮助在线发布商增加其广告收入。所概述的方法已在雅虎实施,并取得了显著成果。年化增量收入估计在雅虎展示广告库存上为+1.3%,在视频广告库存上为+2.5%。在雅虎数百万的广告业务中,这些数字是不可忽视的。

英文摘要:

Floors (also known as reserve prices) help publishers to increase the expected revenue of their ad space, which is usually sold via auctions. Floors are defined as the minimum bid that a seller (it can be a publisher or an ad exchange) is willing to accept for the inventory opportunity. In this paper, we present a model to set floors in first price auctions, and discuss the impact of its implementation on Yahoo sites. The model captures important characteristics of the online advertising industry. For instance, some bidders impose restrictions on how ad exchanges can handle data from bidders, conditioning the model choice to set reserve prices. Our solution induces bidders to change their bidding behavior as a response to the floors enclosed in the bid request, helping online publishers to increase their ad revenue. The outlined methodology has been implemented at Yahoo with remarkable results. The annualized incremental revenue is estimated at +1.3% on Yahoo display inventory, and +2.5% on video ad inventory. These are non-negligible numbers in the multi-million Yahoo ad business.
