Hup Hup Hup here We go.
Youtube Banner: Nice and sleek, like it. Considering putting your scheduling up on it.
Youtube Channel Layout: You have play lists, that's awesome.. But your titles of them are just.. Mm.. I don't know. Playlists are like books and need honest titles that are engaging.. Instead of 'Commentaries' Why not.. 'My Opinions on What you care about'.. Or something like that.
Channel Trailer: Ok.. So the trailer is the first thing I see. You have to remember the title and description matter. So instead of 'My Trailer'.. think of something that might be impressive. For instance, on my channel 'Losoyo' which is political commentary I put 'A channel for Intelligent and Open Minded people'.. Consider doing something like that. Also, Consider your Audience. The first thing I hear is a song that sounds like it may be copyrighted (this will ultimately kill your channel). It's also cursing.. Alot.. Using offensive language.. This may be great for the audience you want, not for me. Now.. Your trailer should tell Who, What, and Why.. You do a good job of explaining what will be on it but it's not the 'who, what, and why'.. I would start with 'Hey, If you're an <X> that loves <Y>, then why the <F> are you not subscribed? Look here's what I got.. and this is why.. Now subscribe YO... or something there of.
Videos: Looking at your latest video ((WarFace) Commentary #5 - Social Media) - On your thumbnails..remember less is more. You don't need text necessarily. Remember that your thumbnail and title are like a book cover..t hey should make the user want to ask a question that needs to be answered by clicking on it. Your music volume (again, copyright music?) - is way to loud, lower that so I can hear you better.
TAGS TAGS TAGS TAGS TAGS -- THIS IS KILLING YOU! Most people have to find you first and they can't if you don't tag! Use youtube search and google search to find applicable drop downs and tag your videos.. You wont get anyone to your content if you don't do this. If you listen to /nothing/ else I have said.. tag every video as much as you can as long as its applicable.
Hope this helps!
