如何通过 Google Analytics 4 跟踪 Adblock 用户

While ExoClick tracks the impressions, clicks and revenue generated by your ad zones, you have other tools at your disposal to measure the overall performance and activity from your website. One of these tools is Google Analytics, which gives you detailed insights on what's happening on your site.

You can set up a custom tracking event in Google Analytics that gives you some indication to how many users are visiting your website with Adblock enabled. This will help you get an idea of how much traffic you could be monetizing through ExoClick's Adblock solution.

Note that we will be referring to the Google Analytics 4 version since Universal Analytics will be discontinued on July 2023.

第 1 步：创建 ad-units.js 脚本并将其上传到服务器

为了检测用户是否在启用 Adblock 的情况下访问我们的网站，我们将创建一个名为 ad-units.js 的 Javascript 文件。该文件声明所有访问网站的用户都没有使用 Adblock。由于 "ad-units "一词被 Adblock 屏蔽，因此只要该文件未加载，我们就会将用户标记为使用广告屏蔽扩展名访问。

.js 文件只需包含以下内容：

isAdBlockActive=false;

创建该文件后，上传至网站服务器。

第 2 步：在每个页面上添加跟踪代码

The default tag from GA tracks basic events such as page views, sessions and users, among others. What we are going to do is to create a custom event using the GA API.

对于此自定义代码，我们将创建 adblock_user 推荐事件。您需要在每个要跟踪的页面上添加以下代码：

<script type="text/javascript">var isAdBlockActive=true;</script>
<script src="ad-units.js" type="text/javascript"></script>
<script>
  window.onload = function(e) {
    if(isAdBlockActive){
      gtag("event", "adblock_user", {
        "user":"adblock"
      })
      console.log('Adblock user')
        } else {
      gtag("event", "adblock_user", {
        "user":"standard"
          })
      console.log('Standard user')
    }
  };
</script>

将此代码放在要跟踪的每个网站的 body 标记之后。让我们来详细了解这段代码的每个部分：

首先，我们将变量 isAdblockActive 声明为 true，这意味着每个访问网站的用户都启用了广告屏蔽。紧接着，我们将调用之前创建的 ad-units.js 脚本，将该变量更改为 false。这意味着用户将被视为 "标准 "用户，除非他们的广告拦截器拦截了ad-units.js文件，在这种情况下，他们将被视为 "adblock "用户。
然后，我们将根据变量 isAdblockActive 是否为 true 创建一个名为 adblock_user 的自定义事件。我们添加了 user 事件参数，以便在 GA 中快速识别。我们将在下一节对此进行详细说明。

Make sure you have placed the basic GA tracking code in the head tag, otherwise the code won't work.
