將Code抽象化的四個元素

Tag｜

Trigger｜

Data Layer｜

Use case (3rd-Party Source Code)

Setting for reusing

Runtime condition

Push data manually (in code)

Core

Example

- Tag

- Varible

- Trigger

蒐集所有使用者所Link點擊的URL

Core

DataLayer

非由tag trigger主動觸發內容

<a href="#" name="button1" onclick="dataLayer.push({'event': 'button1-click'});">

dataLayer.push()

1.使用 Tag 或 DataLayer 的時機

critical issue

https://developers.google.com/tag-manager/devguide

Tag Trigger 可能不如 js 靈活

太多 DataLayer 形同使用 ga sdk

Tag Event Properties 難以使用js產出的內容

交互使用讓GTM與Code仍舊耦合

Google Analytics

使用 Tag

- pageview

- common event

- js error check

- identify

 

使用 DataLayer

- custom pageview (a/b test)

- specific event
