Why Caption Readability Matters for Reels
Maximizing Dwell Time
When a viewer clicks "more" on your caption to read a well-spaced story or tutorial, their session duration on your post increases. This extended dwell time signals to the algorithm that your Reel is valuable and deserves wider feed distribution.
The Power of First-Line Hooks
Only the first 1-2 lines of your caption are visible before the "...more" button. If your opening line doesn't pose an intriguing question or promise high value, users will scroll past without engaging.
