Pro Tips for Getting the Best Results:

Platform Aspect Ratios: Stick to standard aspect ratios (such as 1:1 for square posts and 9:16 for reels/stories) to prevent auto-cropping.
Mobile-First Design: Keep critical text, badges, and logos centered away from the interface edges where platform UI icons can obscure them.
Engagement Boost: Combine tailored captions with targeted, niche-specific hashtags rather than overly saturated generic tags for better reach.
