Caption Writing FAQ

What makes a caption go viral?

Viral captions combine emotional triggers, relatable content, clear value, and perfect timing. They often use pattern interrupts, unexpected twists, or universal truths that resonate widely.

How long should captions be?

Instagram: 125-150 characters for maximum engagement. TikTok: 100-150 characters. Longer captions (500+ chars) work for storytelling but need strong hooks.

When should I use emojis?

Use emojis to break up text, emphasize points, and add personality. Place them at line breaks, after key statements, or as bullet points. Avoid overuse - 3-7 per caption is optimal.
