I still dont totally get why people want to open 100's or 1000's of accounts but thats maybe by the by, i would love to know how to promote a playlist within youtube, can it be promoted within youtube or does it need external backlinks. Does the process of making friends on a channel prove to youtube that this is a healthy channel? I believe that creating playlists acts as a kind of backlink within youtube to the original videos which then i guess lots of channels = lots of playlists = lots of backlinks to original videos? I believe Likes do have a positive effect but possibly the lowest effect and comments are very healthy for a video slightly helping. Any ones advice would be highly welcome.
