A YouTube channel without subs is really a show without an audience also it can become disparaging uploading videos and becoming no fans. In order to get more subscribers you've got to put yourself in their place. A subscriber is someone who enjoys your articles a lot they want to be informed each time your channel is updated with new content. This is a big compliment to provide someone, so it's understandable that does not everyone who views your videos will jump on the subscriber bandwagon. That being said, there's something you can do to improve your turnover and start upping your subscribers.
You got it right; the simplest way to attract more subscribers is by consistently adding more content to your channel on a regular basis. The more you've out there within the sea of YouTube videos, the more likely someone would be to run across one of them and discover your channel.
Additionally, you will wish to set an agenda when ever you release your videos. If people see you are adding new content on a regularly scheduled basis, they are much more likely to subscribe then if they see you haven't added anything in a while so when you probably did it was sporadic.
Interact with Viewers
Nothing builds a sense of community better a content creator who responds and speaks with their audience. If a person comments in your video be sure to thank him or her. If a conversation breaks in the comment section relating to what was posted, chime in and provide your two cents. Whether or not the comments are under friendly, thanks them for giving it a wrist watch and ask for some constructive criticism (until they're trolling obviously). Try ending your video with a call to the viewers asking their ideas on something or perhaps idea for your next video. Getting your viewers involved goes a long way in creating a relationship with them that will keep them around for some time and spread the great word of mount in regards to you.
Take a moment to analyze similar channels to yours that are already successful. Once you have found a few, compose a friendly message explaining a little about your channel and just what you need to do. You might then want to suggest exchanging places on each other's featured lists. Doing this will show a link to their channel out of your channel and vice versa. This is a huge choice for another YouTuber to create, and you may want to wait until you've got a decent video library built up prior to going around asking people. When they help you are committed and pumping out content regularly, they will probably accept your invitation as well as your channel will gain much exposure.
