- Keep the 1.91:1 aspect ratio to avoid cropping on mobile
- High-resolution images prevent pixelation when enlarged
Troubleshooting Social Sharing
If your image doesn't display when sharing:
- Facebook: Use the Facebook Sharing Debugger to refresh cached data
- Twitter: Use the Twitter Card Validator to test your cards
Enter your campaign URL in these tools to fetch fresh metadata.
Common Issues
