ID是全球唯一的吗？ [英] IDs are globally unique?

问题描述

我只想确认广告系列，广告组，关键字和广告的ID在各个帐户中是否具有全球唯一性？

特别是在关键字上： 我相信，在过去，具有各种匹配类型但具有相同文本的关键字具有相同的ID。但是，此行为现在已更改。无论匹配类型如何，所有关键字都具有全局唯一ID。正确？

解决方案

你好。

你是对的。标识符对于给定实体是唯一的，因此例如关键字将在所有关键字中具有唯一的标识符。 

广告组和关键字可以具有相同的标识符虽然。换句话说，ID可能会在不同的实体类型之间重叠。 

最好的问候，

Eric

I just want to confirm that the IDs for campaigns, adgroups, keywords and Ads are globally unique across accounts?

Specifically on keywords:  I believe, in the past, keywords with various match types but same text used to have the same ID. However, this behavior has now changed. All keywords have globally unique IDs irrespective of match type. Correct?

解决方案

Hello.

You are correct. Identifiers are unique for a given entity, so for example a Keyword will have an identifier unique among all Keywords. 

It is possible for an Ad Group and a Keyword to have the same identifier though. In other words IDs might overlap across different entity types. 

Best regards,
Eric
