Share Reel to FB for Maximum Engagement
Learn how to share Instagram Reels to Facebook automatically or manually, optimize captions, and use targeting to boost cross-platform engagement.

Understanding Instagram and Facebook Reels Integration
Sharing engaging short-form video is now easier than ever thanks to Meta’s built-in cross-platform tools. Instagram and Facebook Reels allow creators to connect with vast audiences, and the share reel to FB feature makes repurposing content simple, saving time while boosting reach.
By linking your accounts, you can publish a Reel on Instagram and have it appear on Facebook automatically, tapping into different audience demographics without duplicate uploads. This approach is highly effective for maximizing the impact of your creative output.

Benefits of integration:
- Cross-platform publishing without re-uploads.
- Shared insights across Meta’s analytics ecosystem.
- Larger potential reach from distinct user bases.

Enable Automatic Sharing in Instagram Settings
Automatic sharing ensures that every Reel you post on Instagram is also available to your Facebook audience, expanding your reach without extra effort.
Steps to enable automatic sharing:
- Open the Instagram app.
- Navigate to Profile → Settings → Account → Sharing to Other Apps.
- Link your Facebook account.
- Toggle Share Your Reels to Facebook to ON.
With this enabled, new Reels will appear in your Facebook feed and may also gain traction through Facebook Reels discovery.

Manually Share a Reel to Facebook from Your Feed
Manual sharing lets you choose which Reels cross-post between platforms, giving you flexibility in your content strategy.
How to manually share:
- Open your Instagram feed.
- Locate the Reel to share.
- Tap the three dots menu → Share to Facebook.
- Add a caption if desired and confirm.
This approach allows testing different strategies—posting certain videos on Instagram only, and others across both platforms based on performance goals.

Optimize Reel Captions and Hashtags for Cross-Platform Appeal
Audiences differ between Instagram and Facebook; aligning captions and hashtags with each platform’s culture can improve resonance.
Caption tips:
- Keep captions concise yet impactful.
- Use a hook early—capture attention in the first sentence.
- Include a clear call-to-action (CTA), e.g., "Share your thoughts in the comments!"
Hashtag strategy:
- Blend trending and niche hashtags for optimal visibility.
- Use hashtags on Facebook strategically—though they matter less than on Instagram, they still aid discovery.
- Stick to 5–10 well-targeted hashtags rather than packing too many.

Choose the Right Reel Format and Aspect Ratio
Since Facebook Reels favor vertical video (9:16), identical to Instagram Reels, you can shoot once and distribute twice seamlessly.
Technical specs to meet:
- Aspect ratio: 9:16
- Resolution: ≥ 1080 x 1920 pixels
- Duration: 15–90 seconds
- File formats: MP4 or MOV
Following these specs ensures compatibility and optimal playback across both platforms.

Leverage Facebook Audience Targeting for Reels Visibility
When you share reel to FB, you gain access to robust targeting in Creator Studio or Business Suite.
Targeting options include:
- Age and gender segmentation
- Geographic targeting
- Interest-based categories
- Language settings
Tailored targeting can significantly increase engagement by narrowing distribution to the most relevant viewers.

Analyze Cross-Posted Reels Performance
Facebook Creator Studio allows you to measure the effectiveness of your Reels strategy.
Key metrics:
- Views – Number of times your Reel was watched.
- Watch time – Average view duration before scrolling away.
- Engagement rate – Ratio of likes, comments, and shares to views.
- Demographics – Insights on age, location, and viewer interests.
Analyzing these metrics highlights content types that succeed across platforms.

Test Posting Times for Maximum Engagement
Even strong content can underperform if posted at suboptimal times.
Testing methodology:
- Identify peak engagement periods from past insights.
- Post in varied slots—morning, midday, evening.
- Compare performance data over 2–4 weeks.
Tip: Facebook often peaks around lunch and evening hours; Instagram may rise later at night.

Repurpose Reels for Facebook Stories and Posts
Extending your content’s reach beyond Reels boosts visibility and engagement.
Repurposing ideas:
- Turn behind-the-scenes clips into Stories.
- Share still frames with captions as image posts.
- Feature short Reel clips within carousel posts.
Variety keeps audiences engaged across the Facebook ecosystem.

Avoid Common Mistakes in Cross-Posting Reels
Reduce risk and increase professionalism by avoiding these pitfalls:
- Neglecting caption customization – Adapt text for each platform.
- Using copyrighted audio – Check Facebook’s licensing.
- Cropping errors – Stick to correct ratios to avoid cut-off visuals.
- Posting too frequently – Maintain balance to avoid audience fatigue.
Proper planning keeps your brand image strong on both fronts.
