Text

• Post Character Limit: 63,206 characters

Content Best Practices

Feed Videos (Optimal Length: 1-3 minutes)

• Square or vertical format takes up more screen space
• Text overlays add context for sound-off viewing (85% of users watch without sound)
• Engage early with questions or hooks in first 3 seconds
• Use native uploads rather than shared links
• Include clear call to action

Stories (Optimal Length: 15 seconds or less)

• Full-screen vertical format utilizes entire mobile screen
• Add interactive elements like polls and questions
• Place brand elements consistently
• Include location tags for discoverability
• Keep messaging simple and clear

Technical Considerations

1. Codec Selection: H.264 video codec with AAC audio provides the best compatibility
2. Audio Levels: While Facebook has no official LUFS standard, aim for -14 LUFS integrated with a True Peak of -1 dBTP
3. Safe Zones: Keep important content within the center 80% of the frame to avoid cropping issues
4. Mobile Optimization: Most Facebook content is viewed on mobile devices, so test on mobile before publishing
5. Compression: Use appropriate compression to balance quality and file size

Algorithm Optimization Factors

Facebook's algorithm prioritizes certain content characteristics:

1. Meaningful Interactions (Very High): Create content that sparks conversation
2. Watch Time (High): Create content that holds attention
3. Completion Rate (High): Shorter videos have better completion rates
4. Original Content (Medium-High): Create unique content rather than sharing
5. Recency (Medium): Post when your audience is most active
6. Regularity (Medium): Maintain consistent posting schedule

Best Posting Times

- Day	Best Time (EST)	Secondary Time (EST)
Monday	8-9 AM	2-3 PM
Tuesday	8-9 AM	1-2 PM
Wednesday	11 AM-12 PM	1-2 PM
Thursday	1-2 PM	6-7 PM
Friday	8-9 AM	12-1 PM
Saturday	12-1 PM	8-9 PM
Sunday	11 AM-12 PM	1-2 PM

Common Issues and Solutions

- Issue	Cause and Solution
Low Reach	**Cause**: Algorithm limitations, poor timing. **Solution**: Post when audience is active, create conversation-starting content, use relevant hashtags, boost important posts
Video Quality Issues	**Cause**: Compression, export settings. **Solution**: Export at higher bitrate (8 Mbps), use recommended formats, avoid multiple compression cycles
Audio Problems	**Cause**: Background noise, low volume. **Solution**: Use external microphone, normalize audio to -14 LUFS, apply noise reduction, ensure peaks don't exceed -1 dBTP
Copyright Issues	**Cause**: Using protected music/content. **Solution**: Use Facebook Sound Collection, get proper licenses, create original content
