GoogleAds转换-多个网络请求-为什么？

Question

当我实现一个GoogleAds转换事件时，我会识别多个网络请求到不同的域。有人能解释一下这里发生了什么(以及为什么)吗？

我的想法是向特定端点(或监视系统-> GoogleAds)提供有关某个事件的信息，但我不理解这些多个请求的不同用途。

代码示例

var script = document.createElement('script');
script.src = "https://www.googletagmanager.com/gtag/js?id=AW-XYZ";
document.querySelector("head").appendChild(script);

window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'AW-XYZ');

gtag('event', 'conversion', {
'send_to': 'AW-XYZ/abc123',
'transaction_id': '123456789'
});

网络请求

域名:googletagManager.com/gtag/js?id=AW状态: 200 Type: Script

域名:googleads.g.doubleclick.net s.g.doubleclick.net/pagead/.状态: 200类型:脚本

Answer 1

var script = document.createElement('script');
script.src = "https://www.googletagmanager.com/gtag/js?id=AW-XYZ";
document.querySelector("head").appendChild(script);

gtag核心库从https://www.googletagmanager.com/gtag/js?id=AW-XYZ下载

gtag('config', 'AW-XYZ');

的追踪器。

Next，跟踪转换：

gtag('event', 'conversion', {
'send_to': 'AW-XYZ/abc123',
'transaction_id': '123456789'
});

下载JavaScript for 转换：

https://www.google.com/pagead/conversion_async.js

它提出了第一个跟踪请求。

这将进入/XYZ/

然后联系Doubleclick (在本例中是DMP平台)。

/XYZ/

它还包含小JavaScript，使双击请求。

302按照重定向--在我的情况下，这个请求是HTTP2握手请求的失败。使用http2_handshake_failed base64编码的信息。

然后您将请求全局 Google用户列表：
