開始使用 Google 代碼
Google 代碼是一段程式碼，可在 Google Ads、Google
Analytics 等類似的 Google 產品您不需要管理多個代碼
也可以在各個 Google 產品帳戶中使用 Google 代碼
並將代碼連結至多個目的地。
設定 Google 代碼
設定 Google 代碼的方式，取決於您網站的設定方式及
修改程式碼您可以在網站的下列任一
方法如下：
Google 代碼管理工具：這個代碼管理系統可讓您設定
用來管理網站上的代碼，完全不必修改程式碼。如要使用代碼管理工具
在網站的每個網頁加入 2 段程式碼。加入
您不需要大幅修改程式碼
請改用代碼管理工具網站設定及管理代碼。

The Google tag, a unified code snippet, can be implemented across a website and connected to multiple Google products. Implementation methods include Google Tag Manager, which requires two code snippets and allows tag management without coding, and gtag.js, requiring one code snippet and JavaScript proficiency. Website builders and the Firebase SDK offer integrations for simplified implementation.\n"],null,["# Introduction to tagging and the Google tag\n\nTagging is the process of adding snippets of code (called tags) to each page of\nyour website so you can learn about the people who visit your site and how they\ninteract with it.\n\nTagging is an integral part of many measurement products, including Google Ads,\nGoogle Analytics, and many third-party products too.\n\nWhether you want to know about your most popular blog posts, most effective\nlanding pages, or most popular products, the data you'll collect through tagging\nlets you make more informed decisions about your site and your marketing\nstrategies.\n\nGet started with the Google tag\n-------------------------------\n\nThe Google tag is a single piece of code that you can find in Google Ads, Google\nAnalytics, and other similar Google products. Instead of managing multiple tags\nfor different Google product accounts, you can use the Google tag across your\nentire website and connect the tag to multiple destinations.\n\nSet up the Google tag\n---------------------\n\nSetting up the Google tag depends on how your site is set up and how you can\nchange the code. You can implement the Google tag on your site in one of the\nfollowing ways:\n\n- **Google Tag Manager**: A tag management system that lets you set up and\n manage tags on your site without changing your code. To use Tag Manager, you\n add 2 snippets of code to each page of your website. After you add the\n snippets to your code, you don't need to change your code much after that;\n instead, you can set up and manage your tags through the Tag Manager website.\n\n- **gtag.js**: A JavaScript framework that lets you send data from your site to\n Google measurement products. To set up gtag.js, you add 1 snippet of code to\n each page of your site. To use gtag.js effectively, you need to be comfortable\n changing JavaScript on your site.\n\nIf you use a website builder or content management system like Shopify, Wix, or\nWordpress, the website builder or content management system may offer an\nintegration for setting up Tag Manager or gtag.js on your site.\n\nTo set up measurement and advertising tags in a mobile app,\nuse the Google Analytics for Firebase SDK. Then, you can also\nuse Tag Manager to modify and route data in the mobile app.\n\nNext steps\n----------\n\n- [Plan your tag setup](/tag-platform/devguides/prerequisites)\n- Set up the Google tag with:\n - [Tag Manager](https://support.google.com/tagmanager/answer/6102821)\n - [gtag.js](/tag-platform/gtagjs/install)\n - [a website builder or CMS](https://support.google.com/tagmanager/answer/12403447)\n - [the Google Analytics for Firebase SDK](https://firebase.google.com/docs/analytics)"]]
