FAQ

What makes a caption go viral?

Strong hooks, relatable content, clear CTAs, and emotional resonance drive virality. The first line matters most — it determines whether someone reads on.

How long should an Instagram caption be?

Between 138–150 characters for maximum reach on posts, though longer captions (up to 2,200 chars) work well for storytelling content.

Should I always include a CTA?

Yes — posts with a clear CTA get 89% more engagement on average. Ask a question, ask to save, or direct to your bio link.
