插页式广告（或全屏广告）是一种会覆盖大部分屏幕的广告。因此，在插页式广告展示时，屏幕上不会显示发布商内容。
您可以通过验证出价请求的 BidRequest.imp.instl 字段是否设置为 Protobuf 中的 true 或 JSON 中的 1，来识别出价请求中的插页式广告机会。
广告位尺寸
插页式广告的广告位尺寸表示可用于呈现广告素材的区域，具体取决于特定格式和屏幕尺寸等因素。
OpenRTB 的 BidRequest.imp.banner.format 字段中的第一个宽度和高度对表示实际广告位尺寸，其余对表示符合广告位要求范围的可接受广告尺寸列表。
广告素材不局限于出价请求中的建议尺寸，但出价请求中的所有建议尺寸都保证在可接受的尺寸范围内。
您可以对宽度和高度符合以下条件的任何广告素材出价：
- 小于或等于广告位的宽度和高度
- 大于或等于广告位的 50%
- 大于或等于广告位高度的 40%
如果广告尺寸过大或过小，系统会使用拒绝原因 INTERSTITIAL_SIZE_MISMATCH 滤除出价响应。
如果您未在出价响应中指定广告尺寸，系统会以拒绝原因 MISSING_AD_SIZE 滤除该响应。

最佳做法
Google 建议遵循以下最佳实践：
在 HTML 广告素材摘要中添加格式属性，以便在广告展示位置中居中显示广告。否则，广告会在广告位左上角呈现。
使用插页式广告进行回复，尽可能占据广告位中的所有空间。请勿使用尺寸小得多的广告填充插页式广告位。例如，320x480 的广告尺寸太小，无法填充 420x800 的插页式广告位。
请勿添加任何关闭按钮：
- 我们的 SDK 会自动显示关闭按钮（如果适用），以确保用户可以点击该按钮。
- 不支持 MRAID
useCustomClose()。
使用出价请求中的建议尺寸，为出价响应选择可接受的广告尺寸。
比较
BidRequest.device.w和BidRequest.device.h字段，选择适当的广告素材方向。- 我们建议您制作竖屏和横屏广告素材，以便您以适当的屏幕方向出价。
无尺寸（流体）插页式广告
不限定尺寸的插页式广告（也称为自适应尺寸或自适应插页式广告）会动态调整尺寸，以占据整个广告位的宽度和高度。授权买方不会为您调整广告素材的尺寸。您必须提供可动态调整大小的广告素材。
您只需提交一次无尺寸插页式广告以供审核，即使这些广告可以以多种尺寸投放也是如此。为确保您的广告素材不会针对每个单独的广告位尺寸重新接受审核，我们建议您采取以下措施：
出价响应
在出价响应中使用
BidResponse.seatbid.bid.ext.attribute声明Rendering: Sizeless AdX（属性 105）。可声明的广告素材属性可在 buyer-declarable-creative-attributes.txt 数据文件中找到。根据广告尺寸要求，使用您希望广告素材呈现的尺寸填充
BidResponse.seatbid.bid.w和BidResponse.seatbid.bid.h；例如，对于 360x480 的广告位，填充 360x480。广告素材可能仍会以其他尺寸投放。对于已废弃的 Google RTB 协议，您需要填充BidResponse.Ad.width和BidResponse.Ad.height。
如果您向现有广告素材添加 Rendering: Sizeless AdX 属性，则必须重新审核该广告素材。
广告素材预审批
- 提交广告素材以供审核时，请在
declaredAttributes字段中添加RENDERING_SIZELESS_ADX属性。在实时出价 API 中，广告素材属性使用字符串枚举值表示。如需详细了解这些属性如何与 buyer-declarable-creative-attributes.txt 中的数字 ID 对应，请参阅映射指南。 - 使用您预计投放的尺寸（即插页式广告素材的常用尺寸）提交广告素材。广告素材仍可以其他尺寸投放。
- 每个无尺寸广告素材只会计入广告素材数量限制一次，即使其以多种尺寸投放也是如此。
