# Google AdSense Implementation Strategy

## Overview
Strategic placement of AdSense ads to monetize the developer tools while maintaining excellent user experience. Focus on non-intrusive, contextual ad placements that don't disrupt workflow.

---

## Ad Unit Types & Sizes

### 1. **Display Ads**
- **Leaderboard (728x90)**: Top of pages, above content
- **Medium Rectangle (300x250)**: Sidebar, between content sections (PRIMARY CHOICE)
- **Large Rectangle (336x280)**: Sidebar, high-visibility areas
- **Note**: For our implementation, we use 300x250 for all desktop sidebar ads to comply with Google AdSense policies (no scrollable containers)

### 2. **Responsive Ads**
- Auto-adapt to screen size
- Best for mobile compatibility
- Recommended for all placements

### 3. **In-Feed Ads**
- Native ads that blend with content
- Perfect for tool listings and results

## Placement Strategy

### **Homepage (High Traffic)**

### **Tool Pages (Main Revenue Source)**

**Priority: Balanced UX + Revenue**

```
┌─────────────────────────────────────┐
│ Header / Navigation                 │
├──────────────┬──────────────────────┤
│              │                      │

│              │     (Before export)  │
│              │                      │
│              │  ┌────────────────┐  │
│              │  │ Export Section │  │
│              │  └────────────────┘  │
│              │                      │
└──────────────┴──────────────────────┘
```

**Ad Placements:**
- **Sidebar Ad**: Medium Rectangle (300x250) - Always visible on desktop
- **Ad #1**: Responsive ad between Input and Editor sections
- **Ad #2**: Responsive ad between Editor and Export sections

---

### **Mobile Layout**

**Priority: Non-Intrusive**

```
┌─────────────────────┐
│ Header              │
├─────────────────────┤
│ Input Section       │
├─────────────────────┤
│ 🟦 AD: Responsive   │ ← Ad #1 (Anchor/Banner)
├─────────────────────┤
│ Editor Section      │
├─────────────────────┤
│ 🟦 AD: Responsive   │ ← Ad #2 (Between sections)
├─────────────────────┤
│ Export Section      │
├─────────────────────┤
│ Footer              │
└─────────────────────┘
```

**Mobile-Specific:**
- Use **Anchor Ads** (sticky bottom banner)
- Responsive ads that adapt to screen width
- Fewer ads to maintain UX

## Technical Implementation

### **AdSense Component**

```javascript
// src/components/AdSense.js
import React, { useEffect } from 'react';
import { getCurrentUserTier, USER_TIER } from '../config/features';

const AdSense = ({ 
  slot, 
  format = 'auto',
  responsive = true,
  style = {}
}) => {
  const userTier = getCurrentUserTier();
  
  // Don't show ads for PRO users
  if (userTier === USER_TIER.PRO) {
    return null;
  }

  useEffect(() => {
    try {
      (window.adsbygoogle = window.adsbygoogle || []).push({});
    } catch (e) {
      console.error('AdSense error:', e);
    }
  }, []);

  return (
    <div className="adsense-container my-4">
      <ins
        className="adsbygoogle"
        style={{ display: 'block', ...style }}
        data-ad-client="ca-pub-XXXXXXXXXXXXXXXX" // Your AdSense ID
        data-ad-slot={slot}
        data-ad-format={format}
        data-full-width-responsive={responsive}
      />
    </div>
  );
};

export default AdSense;
```

### **Usage Example**

```javascript
// In TableEditor.js
import AdSense from '../components/AdSense';

// Between sections
<AdSense 
  slot="1234567890" 
  format="auto" 
  responsive={true}
/>

// Sidebar
<AdSense 
  slot="0987654321" 
  format="rectangle"
  style={{ width: '300px', height: '250px' }}
/>
```

### **Add Script to index.html**

```html
<!-- public/index.html -->
<head>
  <!-- Google AdSense -->
  <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-XXXXXXXXXXXXXXXX"
     crossorigin="anonymous"></script>
</head>
```

## Revenue Estimation

### **Traffic Assumptions:**
- 1,000 daily visitors
- 3 page views per visitor = 3,000 page views/day
- 90,000 page views/month

### **AdSense Metrics:**
- Average CPM: $2-5 (developer tools niche)
- Average CTR: 1-2%
- Average CPC: $0.50-2.00

### **Monthly Revenue Estimate:**

**Conservative (Low End):**
- 90,000 page views × $2 CPM = $180/month
- Or: 90,000 × 1% CTR × $0.50 CPC = $450/month

**Optimistic (High End):**
- 90,000 page views × $5 CPM = $450/month
- Or: 90,000 × 2% CTR × $2.00 CPC = $3,600/month

**Realistic Target:** $300-800/month with optimization
