一个竞价响应可包含多个 SeatBid 对象,每个代表一个不同的竞价方席位(bidder seat),各含一条或多条独立出价。若请求中呈现了多个展示,可用 group 属性指明该席位是愿意接受其能赢下的任何展示(默认),还是只有在能整组赢下时才感兴趣。译稿校对中ENA bid response can contain multiple SeatBid objects, each on behalf of a different bidder seat and each containing one or more individual bids. If multiple impressions are presented in the request, the group attribute can be used to specify if a seat is willing to accept any impressions that it can win (default) or if it is only interested in winning any if it can win them all as a group.
| Attribute | Type | Description |
|---|---|---|
| bid required | object[] | 1 个及以上 Bid 对象(参见第 4.2.3 节)的数组,每个 Bid 关联一个展示。多个 Bid 可以关联同一个展示。必填(required)。译稿校对中ENArray of 1+ Bid objects (Section 4.2.3) each related to an impression. Multiple bids can relate to the same impression. |
| seat | string | 本出价所代表的买方席位(buyer seat,如广告主、代理商)的 ID。译稿校对中ENID of the buyer seat (e.g., advertiser, agency) on whose behalf this bid is made. |
| group default 0 | integer | 0 = 各展示可逐一赢标;1 = 各展示必须作为整体同赢或同输。默认值为 0。译稿校对中EN0 = impressions can be won individually; 1 = impressions must be won or lost as a group. |
| ext | object | 供竞价方(bidder)对 OpenRTB 进行专属扩展(bidder-specific extensions)的占位对象。译稿校对中ENPlaceholder for bidder-specific extensions to OpenRTB. |
译注
译者注SeatBid:BidResponse 的子对象,按买方席位(seat)组织出价;业内文档一般保留英文对象名 SeatBid。一个响应可含多个 SeatBid,各代表一个不同的竞价方席位,各自含一条或多条独立出价。译稿校对中
seat:买方席位 ID(席位通常是竞价方账号下的广告主或代理商);请求侧 BidRequest.wseat/bseat 与 Deal.wseat 中的席位词表须与本字段口径一致,且应事先与交易平台协调。译稿校对中
group 的整组语义:group = 0(默认)表示各展示可分别赢标;group = 1 表示“全赢或全输”(all-or-nothing)——任一展示未赢则整组放弃,适用于整页包段(road-blocking)等需要独占上下文的采买场景,交易平台需相应支持整组裁决。译稿校对中
多 Bid 指向同一展示:同一 SeatBid 内的多条 Bid 可关联同一展示(如多套创意轮换、不同价位试探),由交易平台按其规则从中裁决;每条 Bid 通过 impid 关联请求中的 Imp。译稿校对中
