This is a series I have considered as well.
I notice you are unpartnered and just starting out so let me offer you a step in the right direction.
In my signature is a link to the network I am a Media Manager of.
We focus on helping those new or smaller on youtube expand and maximize their content and ideas as well as allowing partners to monetize their videos.
Since you are posting here I can already tell this is on your mind.
One of the main ways to grow is proper tags, description and thumbnail - all of which could be easily improved on that video.
We would be happy to help with this if you decide to check out our network.
Feel free to check out the link below or email us for any questions you'd like answered.
