I've actually found that YouTube videos I post here do not get many views from the forum.
For me, I try to find FB pages that relate to the topic of my videos. For example, if my video is of an abandoned warehouse I'll join a FB group about Abandoned places. Or if I feature a public park or campground I might go to FB groups about the County (that those places resided).
Users on this forum don't like to click a link that takes them out of this app (or a different page if on desktop version) or they are conserving their cell data (or don't have the bandwidth to view the vid in full def so they don't bother).
