Do you have a video that has a topic like “Guide to YouTube Marketing”, but your videos are more higher level than beginner level for the viewers.
You might be losing viewers at the beginning because viewers are looking for a beginner’s level. This action will cause a higher bounce rate and lower watch time.
To help with viewers dropping off your video and leaving your channel, produce a beginner guide video and add the beginner and mention you have a different level and promote that video with a caption. Yes, people will leave that video but they will stay on the channel.
