1st... if you are releasing 5 vids a day by now you should have a ton of videos.... pick the top 3 with the highest views. Focus on getting backlinks to them only. IF that is too many, pick one video to focus on. This 1 video will drive views to all the other videos that are in your channel.
2. Make sure your channel looks nice
3. DO YOUR KEYWORD RESEARCH. Find keywords with lots of views in you tube only.
(you can use the you tube keyword tool, or my tool does that also) After you pick 3-4 Major keywords, see if they have videos in google as well. If they do, that means you can get a double listing, possibly triple if you are lucky.
Google LOVES video and will shoot it above all the other searches. You tube is fairly easy to optimze for if you know what you are doing.... 99% of people don't, which is to YOUR advantage.
3. After you've got your keywords, fill out the rest of your tags by going to other videos in your niche that are at the top and cherry picking some of theirs. For the rest, just get some lsi keywords. You can pack a lot in those tags. (You can overlap your tags for each video... meaning that you can use the same majority of tags for each video)
4. Do your video seo and make sure your description/title, etc have your main keywords in it a few times.
5. download view et --- google it. It's a free software that gets human views by video sharing. Brilliant concept. I have this outsourced right now.
6. Get busy on Fiverr --- get profile links, book marks, buy some human views, likes, comments, you know, the basic backlinking stuff. Get backlinks to that video.
7. Use your imagination from there ;-)
Like I said, I'm too ADD to do all this stuff my self and it would take me forever and I would want to punch myself in the face repeatedly. So to spare myself the agony, I use cheap sources like fiverr.
Good Luck!
