I have a YouTube channel with 5,000+ subscribers. In the past when I would upload a video it would take off almost immediately. Even the videos that didn't do so well would get at least 10 or 20 views per day right off the bat. That doesn't seem to be the case anymore. I recently uploaded four videos and not a single one has taken off. Has YouTube recently changed their algorithms making it much harder for videos in competitive niches to rank? I'm a little confused here.
