You cross-post Instagram Reels to Facebook by linking your Instagram account to your Facebook Page or profile in Accounts Center, then turning on the option to share to Facebook when posting a Reel. You can also set it as the default so every Reel appears on both platforms automatically.
Cross-posting saves time and extends reach, but each audience behaves differently. Facebook viewers often respond better to captions with more context and to relatable or practical content. Review insights on both platforms, and for Reels that underperform on Facebook, consider posting a version with a different caption or hook directly to Facebook instead.
Step-by-step plan
Link Instagram and Facebook in Accounts Center.
Turn on share to Facebook when posting a Reel.
Set cross-posting as default if it fits your strategy.
Adjust captions for Facebook’s audience when needed.
Compare performance on both platforms.
Example: a creator cross-posts every Reel by default and discovers that recipe Reels perform better on Facebook, so they add longer, more detailed captions there.
Why this works
Facebook distributes Reels to people who don't follow you based on predicted watch time, shares and meaningful comments, and it now favours original creators over pages that repost others' clips. Monetization runs through Meta's Facebook Content Monetization program, which combined in-stream ads, Reels ads and performance bonuses into one invitation-based or apply-when-eligible system inside Meta Business Suite and the Professional Dashboard. Eligibility, payouts and available countries change frequently.
Common mistake to avoid
Cross-posting everything without checking results. Some Reels need a different hook for Facebook’s audience.
Pro tip
Reply to comments on both platforms. Cross-posted Reels often get separate discussions, and engaging with each audience strengthens reach.
