Facebook Video: The Subtitle Advantage
Facebook videos autoplay silently in the feed, making subtitles critical for capturing attention. Research shows that captioned videos on Facebook receive 12% more views and significantly higher engagement than those without.
The Facebook algorithm prioritizes content that keeps users on the platform. Videos with higher watch times get more distribution, and subtitles directly contribute to watch time by making content accessible to sound-off viewers.
For business pages, subtitled videos appear more professional and accessible. They demonstrate attention to detail and consideration for all viewers, including the deaf and hard-of-hearing community.
Pro Tips
Optimize for Sound-Off Viewing
Assume 85% of viewers will watch without sound. Your subtitles should tell the complete story independently.
Keep Videos Square for Feed
Square (1:1) videos take up more screen real estate in the Facebook feed. Position subtitles in the lower third for best visibility.
Add Captions to Live Video Replays
Facebook Live videos can be edited after broadcasting. Add subtitles to the replay to extend the life and reach of your content.
Use Contrasting Colors
White text with a black background or outline ensures readability over any video content, which is essential for feed viewing.
