预定位
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
为确保 Google 向您发送最合适的展示调用,您可以使用以下任一方法预定位展示,以便仅接收针对与您的定位条件匹配的展示发送的请求:
配额管理
配额系统按以下四个位置管理配额(如需了解详情,请参阅对等互连下的交易位置):
在每个交易地点,您可以定义多个出价端点(最多 8 个),每个端点由 Authorized Buyers 用户发送出价请求的网址(例如 http://us-east.my_bidder.com:1234/google_rtb
)标识。每个出价端点都有自己的出价邀约限制(以每秒调用次数为单位),您可以通过联系技术支持客户经理或通过 Buyer API 来配置端点及其限制。
配额系统可保证端点收到的出价邀约数量不会超过其出价邀约限制。如果在交易地点,预定位的展示次数少于端点总容量,则配额系统会平衡端点之间的出价邀约。配额系统还实施了错误限制,如果端点的调用程序错误率较高,系统会通过强制执行比配置的调用程序限制更严格的调用程序限制来减轻其负载。如果同一交易地点的其他端点有空闲容量,则错误限制会导致出价邀约转移到这些端点;否则,超出的预定位展示次数将被舍弃。
由于配额管理是在预定位之后进行的,因此不会影响交易地点中预定位的总展示次数。它只能在同一交易地点的端点之间转移出价邀约,或者在出价邀约容量用尽时舍弃过多的预定位展示次数。

Each bidding endpoint has its own callout limit (in\ncallouts per second)---you can configure the endpoints and their limits by\ncontacting your technical account manager or through the [Buyer\nAPI](/authorized-buyers/apis/reference/rest/v2beta1/accounts.clients/update).\n\nThe quota system guarantees that an endpoint does not get more callouts than\nits callout limit. If in a trading location where there are less pretargeted\nimpressions than the total endpoint capacity, the quota system balances the\ncallouts among the endpoints. The quota system also implements error\nthrottling---if an endpoint has high callout error rate, the system\nlightens its load by enforcing a stricter callout limit than the configured\none. If there is spare capacity in other endpoints in the same trading\nlocation, error throttling will cause the callouts to shift to them; otherwise\nthe excess pretargeted impressions will be dropped.\n\nBecause quota management comes after pretargeting, it does not affect the\ntotal number of pretargeted impressions in a trading location. It can only\nshift callouts among endpoints in the same trading location, or drop excess\npretargeted impressions if the callout capacity is exhausted."]]
