谷歌分析有两种方式：
1 Universal Analytics （旧版）
2 Google Analytics （新版）
使用gtag和Google Tag Manager(TMS)谷歌代码跟踪管理器两种方式 区别
Universal Analytics 是 Google Analytics（分析）的早期版本，仅支持网站衡量功能。
创建账号后获取代码这是针对此媒体资源的全局网站代码 (gtag.js) 跟踪代码。请复制此代码，并将其作为第一个项目粘贴到您要跟踪的每个网页的 <HEAD> 标记中。如果您的网页上已经有全局网站代码，则只需将以下代码段中的 config 行添加到现有的全局网站代码。事件代码
<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-154795933-1"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'UA-154795933-1');
</script>
<!-- Event snippet for Click to Store and Twitter conversion page In your html page,
add the snippet and call gtag_report_conversion when someone clicks on the chosen link or button. -->
<script>
function gtag_report_conversion(url) {
var callback = function() {
if (typeof(url) != 'undefined') {
window.location = url;
}
};
gtag('event', 'conversion', {
'send_to': 'AW-328469561/dBn9CJTm3N4CELmY0JwB',
'event_callback': callback
});
return false;
}
</script>
<div onclick="gtag_report_conversion('https://arkajp-test.ulugame.com/')"></div>
window.gtag("event", "conversion", {
send_to: "AW-328469561/SFBxCIqUtOICELmY0JwB"
});
//gtag_report_conversion是自定义事件，可以在a标签跳转，button按钮，或者img图片中埋点
可以使用 [Google Tag Assistant]（https://support.google.com/tagassistant/answer/2947093?hl=en） 来确定自己的代码是否已正确植入。
google ads 和Google Analytics 是两个后台，一个是广告投放的埋点，一个是谷歌分析的埋点，可以将二者关联起来
