## 🎯 Use Cases

### 1. Validate Google Alert Queries
Test if your alert queries actually return results:
```bash
node scripts/validate-scraping.js docs/google-alerts-broad.md
```

### 2. Scrape Search Results
Get actual search results with full details:
```bash
node scripts/playwright-scraper.js '"laptop repair" Toronto'
```

### 3. Monitor Reddit
Scrape Reddit with human-like behavior:
```bash
node scripts/playwright-scraper.js --url "https://www.reddit.com/r/toronto"
```

### 4. Custom Scraping
Use the library in your own scripts:
```javascript
import { humanClick, humanType, humanScroll } from './scripts/human-behavior.js';
```

## 📝 Example Output

### Single Query Validation
```
🔍 Searching Google for: "macbook repair" Toronto

📊 Results Summary:
   Stats: About 1,234 results (0.45 seconds)
   Found: 15 results

✅ Query returned results:

1. MacBook Repair Toronto - Apple Certified
   https://example.com/macbook-repair
   Professional MacBook repair services in Toronto...
```

### Batch Validation Report
```json
{
  "total": 5,
  "successful": 4,
  "failed": 1,
  "successRate": 80,
  "results": [...]
}
```

## 🔧 Customization

All behavior parameters are configurable in `scripts/scraper-config.js`:

```javascript
mouse: {
  overshootChance: 0.15,      // 15% chance to overshoot
  overshootDistance: 20,       // pixels
  pathSteps: 25,              // bezier curve resolution
}

scroll: {
  minAmount: 100,             // minimum pixels
  maxAmount: 400,             // maximum pixels
  randomDirectionChance: 0.15 // 15% chance to reverse
}

typing: {
  minDelay: 50,               // fastest typing
  maxDelay: 150,              // slowest typing
  mistakeChance: 0.02         // 2% typo rate
}
```

## 🧪 Testing

Run the comprehensive test suite:

```bash
# With visible browser (recommended for learning)
npm run test:headed

# Headless (faster)
npm test

# Specific test file
npx playwright test tests/human-behavior.test.js --headed
```

## ⚠️ Important Notes

### Rate Limiting
- Default delay: 5 seconds between requests
- Recommended: 10-15 seconds for production
- Google may still show CAPTCHAs with heavy usage

### Legal & Ethical Use
- Always respect robots.txt
- Follow website Terms of Service
- Use reasonable rate limits
- Don't overload servers

### Best Practices
1. Start with `--headless false` to see behavior
2. Increase delays between requests
3. Test queries in small batches first
4. Monitor for CAPTCHAs or rate limiting
5. Use different IP addresses for high volume

## 🎓 Learning Resources

1. **Start Here**: `docs/QUICKSTART_PLAYWRIGHT.md`
2. **Full API**: `docs/PLAYWRIGHT_SCRAPING.md`
3. **Examples**: `scripts/example-usage.js`
4. **Tests**: `tests/human-behavior.test.js`
5. **Config**: `scripts/scraper-config.js`

## 🔜 Next Steps

1. ✅ Install dependencies: `npm install`
2. ✅ Install browser: `npx playwright install chromium`
3. 🎯 Try example: `node scripts/example-usage.js 1`
4. 🧪 Run tests: `npm run test:headed`
5. ✅ Validate alerts: `node scripts/validate-scraping.js docs/google-alerts-broad.md`
6. 🚀 Start scraping with confidence!

## 💡 Tips

- **Headed mode** (visible browser) is great for development
- **Headless mode** is faster for production
- Use `--max 3` when testing to limit requests
- Increase `--delay` if you encounter rate limiting
- Check console output for detailed behavior logs

## 🎉 You're Ready!

Your Playwright setup is complete with state-of-the-art bot detection avoidance. All the tools, examples, and documentation you need are in place.

Happy scraping! 🚀
