The 3 Pillars of Retention-Boosting Captions
One-to-Three Word Pacing
Avoid blocks of text. Fast 1-3 word bursts keep the eye continually engaged on the screen.
Dual-Tone Color Sync
Using contrasting colors (e.g., lime green on white text) guides the reader's focus as words are spoken.
Contextual Emojis
Auto-injecting visual markers on key nouns elevates emotional impact and retention metrics.
