How to increase Youtube Channel Subscribers?

Dear all, I have produced a couple of videos in my channel but it seems that the number of subscribers is not increasing that much. Any good method to increase?

Anyway, I have just uploaded my new video- Rolling In The Deep, re-arranged and re-made. Please support yo. Comment and critic to help me improve

Come to my channel and comment: canuteckit1987

Buy them!

Buying subscribers definitely would help a ton for your channel.

Cheers,
