How it works
Frequently asked questions
- What makes a good Instagram caption?
- A great Instagram caption starts with a hook that makes the viewer tap 'more', delivers value or entertainment in the body, and ends with a clear CTA (comment, save, or visit link). Emojis should guide the eye rather than overpower the text. Caption length depends on the content type: Reels perform better with shorter captions, while carousels and static posts often benefit from longer storytelling captions.
- Should TikTok captions be long or short?
- TikTok captions should be short and direct — typically under 100 characters — because viewers focus on the video itself. The caption supports the video rather than carrying the content. Including 1-2 relevant keywords in your TikTok caption also helps TikTok's algorithm categorize your content for discovery.
- How do LinkedIn captions differ from Instagram captions?
- LinkedIn captions are longer, more professional, and structured as thought-leadership content rather than visual enhancement. Effective LinkedIn captions use a bold first line to stop the scroll, follow a narrative or list structure, and end with a question to drive comments. Hashtags on LinkedIn are less important than on Instagram but should be topically relevant.
