当承载广告的内容是网站而非非浏览器应用或数字户外（DOOH）库存时，应包含该对象。一个竞价请求不得同时包含 Site、App、DOOH 对象中的多个。至少提供站点 ID 或页面 URL 是有用的，但这并非严格要求。译稿校对中ENThis object should be included if the ad supported content is a website as opposed to a non-browser application or Digital Out of Home (DOOH) inventory. A bid request must not contain more than one of a Site, App or DOOH object. At a minimum, it is useful to provide a site ID or page URL, but this is not strictly required.

译注
译者注Site 的三方互斥：2.6 中分发渠道扩展为 Site ⊕ App ⊕ DOOH 三方互斥（数字户外屏幕见 DOOH 对象），同一请求至多包含其一；至少提供站点 ID 或页面 URL 是有用的。译稿校对中
page / domain 的核验价值：page 是语境化定向与品牌安全的核心字段；page 域名与 domain 的一致性核验是反作弊（域名仿冒检测）的基础步骤，二者不一致时应触发风控审查。译稿校对中
cattax 与三级分类配套：cat/sectioncat/pagecat 逐层细化，均受 cattax 声明的分类体系版本约束；省略 cattax 时默认 IAB 内容分类 1.0，跨版本词表不可混用。译稿校对中
inventorypartnerdomain 的授权机制：服务于内容联盟（如嵌入第三方视频/文章）场景的库存授权：内容所有者在其自身域名的 ads.txt 中声明供给授权，站点所有者在自己的 ads.txt 中以 inventorypartnerdomain 引用；买方验证链路时需同时核对两处 ads.txt，缺一即视为未授权供给。译稿校对中
ref / search 的隐私限制：受浏览器 Referrer-Policy 等隐私策略影响，ref 可能被裁剪或缺失；流量来源分析不应完全依赖这两个字段。译稿校对中
