  4. Test Different Formats
    • Experiment with horizontal, vertical, and square formats to see which performs best with your audience.
  5. Leverage Thumbnails and Companion Banners
    • Use attractive thumbnails and companion banners to catch the viewer’s attention and reinforce your message. Ensure they are within the required size and format limits.
  6. Use Appropriate File Formats
    • Stick to common file formats like MP4 for videos and JPEG, GIF, or PNG for thumbnails and banners. This ensures compatibility and smooth playback across different devices and platforms.
