Testing Meta Pixel Events

1. Meta Pixel Helper

1. Install Meta Pixel Helper extension
2. Visit your Joomla site
3. Trigger events (view article, add to cart, etc.)
4. Check extension icon - should show green checkmark
5. Verify events appear in popup

2. Events Manager Test Events

1. Facebook Events Manager → Test Events
2. Enter your Joomla site URL
3. Browse site and trigger events
4. Verify events appear in real-time
5. Check event parameters are correct

3. Browser Console

// Check if fbq is loaded
console.log(window.fbq);

// Manually fire test event
fbq('track', 'ViewContent', {
    content_name: 'Test Product',
    content_ids: ['123'],
    content_type: 'product',
    value: 99.99,
    currency: 'USD'
});

Common Issues

Events not firing:

Check fbq is loaded: console.log(window.fbq)
Verify Pixel ID is correct
Check browser console for JavaScript errors
Ensure event listener attached after DOM loads

Events fire multiple times:

Remove duplicate tracking code
Check session deduplication for purchase events
Verify no extension conflicts
