How do I write captions that get comments?
By the VIRAL AI team · Updated · 2 min read
The short answer
You write captions that get comments by asking specific, easy-to-answer questions, inviting opinions or creating friendly debate. Comments come when viewers feel their answer matters and responding takes little effort.
Ask binary choices (“coffee or tea?”), request personal experiences (“what was your first job?”) or invite predictions (“guess the price”). Make the question relevant to the video. Respond to comments to encourage more engagement. Avoid generic prompts like “thoughts?” that give viewers little direction.
Step-by-step plan
Ask a specific, easy-to-answer question.
Use binary choices or predictions.
Invite personal experiences related to the video.
Make the question relevant to the content.
Reply to comments to keep conversation going.
Example: a caption reading “guess how much this vintage chair cost” gets 2,500 comments on a 100,000-view video, far above the creator’s average.
Why this works
Short-form viewers decide in about one to three seconds whether to keep watching, so the hook carries more weight than any other part of the video. Strong hooks combine a visual pattern interrupt, a spoken or on-screen promise and an open loop the viewer needs closed. The rest of the video must deliver on that promise quickly, and the caption should add context or a question that invites comments rather than repeating what is already on screen.
Common mistake to avoid
Using vague prompts like “thoughts?”. Specific questions get far more responses.
Pro tip
Ask viewers to guess something revealed later, like a price or result. Guessing games drive comments and watch time.
Check it before you post
Don't guess why your video is stuck.
