Workflow

工作流程

Phase 1: Codebase Discovery

第一阶段：代码库探索

Detect Framework
- Check package.json for React, Next.js, Vue, or other frameworks
- Note version and routing approach (Next.js App Router vs Pages Router)
- Identify component file patterns (
```
.tsx
```
  ,
```
.jsx
```
  ,
```
.vue
```
  )
Identify Component Files
- Scan for all component files in common directories:
  - ```
  app/**/*.tsx
```
  (Next.js App Router)
- ```
pages/**/*.tsx
```
    (Next.js Pages Router)
  - ```
  components/**/*.{tsx,jsx,vue}
```
- ```
src/**/*.{tsx,jsx,vue}
```
- Priority: Start with layout, navigation, and page components

检测框架
- 检查package.json，识别React、Next.js、Vue或其他框架
- 记录版本和路由方式（Next.js App Router vs Pages Router）
- 识别组件文件格式（
```
.tsx
```
  ,
```
.jsx
```
  ,
```
.vue
```
  ）
识别组件文件
- 扫描常见目录中的所有组件文件：
  - ```
  app/**/*.tsx
```
  （Next.js App Router）
- ```
pages/**/*.tsx
```
    （Next.js Pages Router）
  - ```
  components/**/*.{tsx,jsx,vue}
```
- ```
src/**/*.{tsx,jsx,vue}
```
- 优先级：从布局、导航和页面组件开始

Phase 2: Clickable Element Scanning

第二阶段：可点击元素扫描

Scan all component files for trackable interactive elements:

Button Elements:

jsx

<button>...</button>
<button onClick={...}>
<Button>...</Button> (component)

Link Elements:

jsx

<a href="...">
<Link href="..."> (Next.js/React Router)
<router-link to="..."> (Vue)

Form Elements:

jsx

<form onSubmit={...}>
<form action="...">

Media Elements:

jsx

<video controls>
<audio controls>
<iframe> (YouTube, Vimeo embeds)

Custom Interactive Elements:

jsx

<div onClick={...}>
<span role="button">
Elements with cursor: pointer

扫描所有组件文件中的可交互追踪元素：

按钮元素：

jsx

<button>...</button>
<button onClick={...}>
<Button>...</Button> (component)

链接元素：

jsx

<a href="...">
<Link href="..."> (Next.js/React Router)
<router-link to="..."> (Vue)

表单元素：

jsx

<form onSubmit={...}>
<form action="...">

媒体元素：

jsx

<video controls>
<audio controls>
<iframe> (YouTube, Vimeo embeds)

自定义交互元素：

jsx

<div onClick={...}>
<span role="button">
Elements with cursor: pointer

Phase 3: Element Categorization

第三阶段：元素分类

Categorize each element by purpose:

CTA (Call-to-Action): Primary action buttons
- "Get Started", "Sign Up", "Start Trial", "Book Demo", "Download"
- Usually styled as primary/prominent buttons
Navigation: Menu links and page navigation
- Header/navbar links, footer links, sidebar navigation
- Breadcrumbs, pagination
Form: Data capture and submission
- Contact forms, newsletter signup, search inputs
- Lead capture, login/signup forms
Pricing: Pricing and plan selection
- Plan comparison, "Choose Plan", upgrade CTAs
Auth: Authentication actions
- Login, logout, signup, forgot password
Demo: Product demo requests
- "Watch Demo", "Schedule Demo", demo video players
Outbound: External links
- Social media, partner sites, documentation
Media: Video and audio interactions
- Play, pause, seek, volume controls

按用途对每个元素进行分类：

CTA（行动召唤）：主要行动按钮
- 「开始使用」、「注册」、「开始试用」、「预约演示」、「下载」
- 通常设计为主要/突出按钮
导航：菜单链接和页面导航
- 页眉/导航栏链接、页脚链接、侧边栏导航
- 面包屑、分页
表单：数据采集与提交
- 联系表单、新闻通讯订阅、搜索输入框
- 潜在客户采集、登录/注册表单
定价：定价与方案选择
- 方案对比、「选择方案」、升级CTA
认证：认证操作
- 登录、登出、注册、找回密码
演示：产品演示请求
- 「观看演示」、「预约演示」、演示视频播放器
外部链接：外部站点链接
- 社交媒体、合作站点、文档
媒体：视频与音频交互
- 播放、暂停、快进、音量控制

Phase 4: Existing Tracking Analysis

第四阶段：现有追踪分析

Scan for existing tracking implementation:

DataLayer Usage:

javascript

window.dataLayer.push({...})
dataLayer.push({...})

Event Handlers with Tracking:

javascript

onClick={() => {
  // Track event
  window.dataLayer.push({...})
  // Or analytics.track(...)
}}

Analytics Libraries:

Google Analytics (ga, gtag)
Segment (analytics.track)
Mixpanel
Custom analytics implementations

Track Coverage:

Count elements WITH tracking
Count elements WITHOUT tracking
Identify tracking patterns used

扫描现有追踪实现：

DataLayer使用情况：

javascript

window.dataLayer.push({...})
dataLayer.push({...})

带有追踪的事件处理器：

javascript

onClick={() => {
  // Track event
  window.dataLayer.push({...})
  // Or analytics.track(...)
}}

分析库：

Google Analytics (ga, gtag)
Segment (analytics.track)
Mixpanel
自定义分析实现

追踪覆盖率：

统计已添加追踪的元素数量
统计未添加追踪的元素数量
识别使用的追踪模式

Phase 5: DOM Structure Evaluation

第五阶段：DOM结构评估

Evaluate each element's analytics readiness:

ID Attributes:

Clear, descriptive IDs:
```
id="cta_hero_get_started"
```
✓
Generic IDs:
```
id="button1"
```
✗
Missing IDs: No id attribute ✗

Class Attributes:

Analytics classes:
```
class="js-track js-cta js-click"
```
✓
Generic classes:
```
class="btn primary"
```
△ (functional but not analytics-ready)
Inline styles only: No class attribute ✗

Accessibility:

Semantic HTML:
```
<button>
```
vs
```
<div onClick>
```
✓
ARIA labels:
```
aria-label="..."
```
✓
Alt text on images used in buttons

评估每个元素的分析就绪状态：

ID属性：

清晰、描述性的ID：
```
id="cta_hero_get_started"
```
✓
通用ID：
```
id="button1"
```
✗
缺少ID：无id属性 ✗

类属性：

分析专用类：
```
class="js-track js-cta js-click"
```
✓
通用类：
```
class="btn primary"
```
△（功能性可用但不具备分析适配性）
仅内联样式：无类属性 ✗

可访问性：

语义化HTML：
```
<button>
```
vs
```
<div onClick>
```
✓
ARIA标签：
```
aria-label="..."
```
✓
按钮中图片的替代文本

Phase 6: Gap Analysis

第六阶段：差距分析

Identify issues and opportunities:

Naming Issues:

Generic button names ("button1", "btn", "primary")
Missing identifiers (no id or meaningful classes)
Inconsistent naming patterns

Tracking Gaps:

High-value elements without tracking (CTAs, forms)
Incomplete tracking (only some CTAs tracked)
Missing event parameters

Framework-Specific Issues:

Next.js: Missing 'use client' directives for client-side tracking
React: Event handlers not tracking clicks
Vue: Missing event listeners for analytics

识别问题与机会：

命名问题：

通用按钮名称（"button1", "btn", "primary"）
缺少标识符（无id或有意义的类）
命名模式不一致

追踪差距：

高价值元素未添加追踪（CTA、表单）
追踪不完整（仅部分CTA添加了追踪）
缺少事件参数

框架特定问题：

Next.js：客户端追踪缺少'use client'指令
React：事件处理器未追踪点击
Vue：缺少分析事件监听器

Phase 7: Recommendations

第七阶段：建议

Provide actionable recommendations:

DOM Standardization Needs
- "Standardize 23 button identifiers before implementing tracking"
- "Add analytics classes to 15 links"
- "Create consistent naming convention across components"
Priority Tracking Opportunities
- P0: CTAs and forms (high conversion impact)
- P1: Navigation and outbound links (user journey)
- P2: Media interactions and scroll events (engagement)
Next Steps
- "Run gtm-dom-standardization to clean up DOM structure"
- "Run gtm-strategy to plan tracking implementation"

提供可执行的建议：

DOM标准化需求
- 「在实施追踪之前，标准化23个按钮的标识符」
- 「为15个链接添加分析专用类」
- 「在组件间创建一致的命名规范」
优先级追踪机会
- P0：CTA和表单（高转化影响）
- P1：导航和外部链接（用户旅程）
- P2：媒体交互和滚动事件（用户参与度）
后续步骤
- 「运行gtm-dom-standardization来清理DOM结构」
- 「运行gtm-strategy来规划追踪实现」

Phase 8: Output Generation

第八阶段：输出生成

Important Guidelines

重要指南

Senior Engineer Mindset

资深工程师思维

Be thorough but efficient: Scan comprehensively but summarize clearly
Identify root causes: Don't just report "missing tracking" - explain why (no IDs, generic classes, etc.)
Provide context: Explain business impact of each finding
Think systematically: Categorize and prioritize systematically

全面且高效：全面扫描但清晰总结
识别根本原因：不要只报告「缺少追踪」，要解释原因（无ID、通用类等）
提供上下文：解释每个发现的业务影响
系统化思考：系统化地分类和排序优先级

Framework-Specific Awareness

框架特定认知

Next.js App Router:

Client components need 'use client' directive for tracking
Server components cannot use onClick directly

React:

Event handlers should include tracking calls
Hooks (useState, useEffect) may affect tracking timing

Vue:

Composition API vs Options API affects event binding
Template syntax differences from React

Next.js App Router：

客户端组件需要'use client'指令才能实现追踪
服务器组件不能直接使用onClick

React：

事件处理器应包含追踪调用
Hooks（useState、useEffect）可能影响追踪时机

Vue：

Composition API与Options API会影响事件绑定
模板语法与React不同

Categorization Logic

分类逻辑

Use this decision tree for ambiguous elements:

"Learn More" button:

If leads to product demo → CTA
If navigates to info page → Navigation
Default: CTA (assumes conversion intent)

"Contact Us" link:

In navigation menu → Navigation
As prominent button → CTA
In footer → Navigation

Video player:

Auto-play background video → Media
Product demo video → Demo + Media

Search input:

Header search → Form + Navigation
Content filter → Form

对模糊元素使用以下决策树：

「了解更多」按钮：

如果指向产品演示 → CTA
如果导航到信息页面 → 导航
默认：CTA（假设存在转化意图）

「联系我们」链接：

在导航菜单中 → 导航
作为突出按钮 → CTA
在页脚中 → 导航

视频播放器：

自动播放背景视频 → 媒体
产品演示视频 → 演示 + 媒体

搜索输入框：

页眉搜索 → 表单 + 导航
内容筛选 → 表单

Avoid Over-Engineering

避免过度设计

Don't recommend tracking EVERY element
Focus on business-critical interactions
Skip decorative or redundant elements
Prioritize based on conversion impact

不要建议追踪所有元素
专注于业务关键交互
跳过装饰性或冗余元素
根据转化影响确定优先级

Common Questions

常见问题

Q: Should I track every button? A: No. Focus on conversion-critical CTAs, forms, and navigation. Skip redundant/decorative elements.

Q: How do I categorize ambiguous elements? A: Use business intent: Does it drive conversion (CTA) or navigate (nav)? Default to CTA if unclear.

Q: What if the codebase has no tracking at all? A: That's common! Focus on identifying opportunities and recommend starting with P0 elements (CTAs, forms).

Q: Should I scan node_modules? A: No. Only scan user code (app/, components/, pages/, src/). Ignore node_modules and build directories.

Q: 我应该追踪每个按钮吗？ A: 不需要。专注于转化关键的CTA、表单和导航。跳过冗余/装饰性元素。

Q: 如何对模糊元素进行分类？ A: 依据业务意图：是否推动转化（CTA）或导航（导航）？如果不确定，默认归类为CTA。

Q: 如果代码库完全没有追踪怎么办？ A: 这很常见！专注于识别机会，并建议从P0元素（CTA、表单）开始。

Q: 我应该扫描node_modules吗？ A: 不需要。仅扫描用户代码（app/、components/、pages/、src/）。忽略node_modules和构建目录。
