Hi Noah,

When posting, you have to keep in mind that, though videos generally do well for most posters, this won't necessarily be true for all. What works and what doesn't depends more on your demographics and the trends thereof.

You should also keep in mind that there are many factors at play which determine a post's engagement - the accompanying text, the format, the time of day, etc.

My recommendation would be A/B testing. One example I can think of off the top of my head would be to post twice in 2 days - once with the video as you've been doing, and once as an image/link that directs to the video in some way. A/B testing can often help to define the reasons behind trends in your groups of fans.

I hope that's been helpful! Cheers!
