Do you create separate content for Facebook or use Cfosspost feature to post Instagram Posts, Reels & Stories to Facebook Page. I am asking this to you as a creator?
I would say to make separate content. This because the algos are different from each other.
Instead of cross posting you should repurpose and adapt your content. if you create an Instagram Reel you can re upload it to Facebook with a different and more conversational caption. This small change helps you get better results on both platforms. I hope this helps
