# 台灣電商的 GA4

> **STATUS: SKELETON**：內文待補。

## 何時使用這個 skill

- 替台灣商店埋 GA4 Enhanced Ecommerce
- 稽核既有 GA4 設定是否符合台灣慣例
- 設計台灣 KPI 的 Looker Studio 報表
- 設定 BigQuery 匯出
- 跨 LINE OA / 電商平台通路做歸因

## 何時「不要」使用

- 一般分析 → `ecom-analytics`
- 只要基準 → `tw-ecom-analytics-benchmarks`

## 核心概念

TODO: GA4 事件模型、含稅 revenue 的處理、幣別 = TWD、用 content_group 標示檔期。

## 決策樹

TODO: 事件 → 符合台灣慣例的參數對應。

## 實作指引

TODO: dataLayer 範本、tag 設定、consent mode、BigQuery 匯出。

## 常見陷阱

TODO: 5-6 個陷阱（含稅重複計算、跨網域電商平台歸因、LINE IAB 追蹤被擋、consent-mode 下 revenue 低估、參數基數上限）。

## IRON LAW

TODO.

## 輸出格式

# GA4 for Taiwan E-Commerce

> **STATUS: SKELETON** — body pending.

## When to use this skill

- Instrumenting a TW store with GA4 Enhanced Ecommerce
- Auditing an existing GA4 setup for TW conventions
- Designing Looker Studio reports for TW KPI
- Setting up BigQuery export
- Attributing across LINE OA / marketplace channels

## Do NOT use when

- Generic analytics → `ecom-analytics`
- Benchmarks only → `tw-ecom-analytics-benchmarks`

## Core concepts

TODO: GA4 event model, 含稅 revenue handling, currency = TWD, content_group usage for 檔期.

## Decision tree

TODO: event → parameter mapping for TW conventions.

## Implementation guidance

TODO: dataLayer template, tag setup, consent mode, BigQuery export.

## Gotchas

TODO: 5-6 pitfalls (含稅 double-count, cross-domain marketplace attribution, LINE IAB tracking block, consent-mode revenue undercount, parameter cardinality limits).

## IRON LAW

TODO.

## Output Format

TODO.
