How to Upload Facebook Reels

Facebook Reels often gets overlooked by creators focused on TikTok and Instagram. That's a mistake. Facebook still has nearly 3 billion users, and its Reels feature reaches demographics that don't use other short-form video apps—particularly the 30+ audience.

If you're already creating short-form video, uploading to Facebook takes minimal extra effort and opens up an audience you're probably missing entirely.

Reels Requirements

Duration: No length limit (under 90 seconds recommended for best engagement)
Aspect ratio: 9:16 vertical
Resolution: 1080x1920 recommended
Format: MP4
File size: Up to 4GB

Uploading from Mobile

1. Open the Facebook app
2. Tap the Reels tab or tap Create and select Reel
3. Tap the gallery icon to upload an existing video
4. Add music, effects, or text if desired
5. Write your description with hashtags
6. Tap Share to Reels

The mobile app gives you access to Facebook's built-in effects, music library, and text overlays. If you want to post a polished video you've already edited elsewhere, skip the effects and just upload your finished file.

Uploading from Desktop

For desktop uploads, use Meta Business Suite (formerly Creator Studio):

1. Go to business.facebook.com
2. Select your Facebook Page
3. Click Create Post then select Reel
4. Upload your video file
5. Add description, hashtags, and configure settings
6. Publish immediately or schedule for later

Desktop uploading is better for batch workflows. You can upload multiple Reels in one session and schedule them across the week. Meta Business Suite also shows a calendar view of all your scheduled content, making it easy to spot gaps in your posting schedule.

How the Facebook Reels Algorithm Works

Facebook's Reels algorithm shares some DNA with Instagram's (both are Meta), but behaves differently in practice:

• -Shares and comments matter most: Facebook's algorithm weighs social interactions more heavily than passive viewing. Content that people share to friends or comment on gets pushed much further.
• -Watch time is secondary: Unlike TikTok where watch-through rate is king, Facebook cares more about whether your video sparks a conversation or gets shared to Messenger.
• -Group distribution: Reels can surface in Facebook Groups related to your content topic. This is unique to Facebook and can drive highly targeted views.
• -Older content can resurface: Facebook's algorithm sometimes pushes older Reels weeks or months after posting if they match a user's interests. This gives Reels a longer shelf life than on TikTok.

Writing Captions for Facebook Reels

Facebook captions behave differently than on other platforms. The audience is older on average and tends to read more before watching. Here's what works:

Go longer than you would on TikTok

On TikTok, short captions with a few hashtags are standard. On Facebook, longer captions that provide context or ask a question consistently outperform. Give your audience a reason to comment—opinions, questions, and "tag someone who" prompts work well.

Use 3-5 relevant hashtags

Facebook hashtags don't drive as much discovery as TikTok hashtags, but they help categorize your content for the algorithm. Stick to relevant, specific hashtags rather than broad ones. #CookingTips is better than #Viral.

Add captions to the video itself

Facebook users watch on mute even more than other platforms. Burned-in captions or text overlays on the video are essential—don't rely on Facebook's auto-generated captions alone. For more on captioning, see our guide to adding captions to short-form videos.

Facebook Reels Monetization

Facebook offers monetization for Reels through overlay ads—banner and sticker ads that appear on your Reels. To qualify, you need:

• -10,000 followers on your Facebook Page
• -600,000 total minutes viewed in the last 60 days
• -5 or more active videos on your Page
• -Compliance with Meta's Partner Monetization Policies

Earnings vary by niche and audience location. US and UK audiences generate higher CPMs (revenue per 1,000 views) than most other regions. Creators in finance, tech, and business niches tend to earn more per view than entertainment creators.

Optimizing for Facebook

Post timing

Facebook's audience is most active mid-day on weekdays. The 1-3 PM window on Wednesday through Friday tends to produce the best results. Avoid early morning and late night—Facebook usage drops significantly outside business hours compared to TikTok.

Content that works on Facebook

The Facebook audience responds well to informative, relatable, and longer-form content. How-tos, tips, and explainers outperform trend-based content. Cooking, DIY, parenting, finance, and local business content performs particularly well on Facebook compared to other platforms.

Avoid TikTok watermarks

Facebook's algorithm deprioritizes videos with visible TikTok watermarks. If you're cross-posting, always upload the original clean file rather than downloading from TikTok. The same applies to Instagram Reels watermarks.

Cross-Posting to Other Platforms

Since Meta owns both Facebook and Instagram, you can enable automatic cross-posting between them. When you post a Reel to Facebook, you can choose to also share it to Instagram Reels (and vice versa). This saves time but means you can't customize captions for each platform.

For more control, upload separately to each platform with customized captions. Tools like ShortSync let you upload once and customize for both platforms—plus TikTok and YouTube Shorts—before posting.
