I agree with Symph there, content is always king when it comes to anything including videos and people watch and like good interesting content, to keep people watching you need to be doing or showing them something interesting to them, that could just be your personality, telling them a joke or ranting and having a laugh at the same time but talking about something specific is usually best like say you got a new phone you could show them it, take them through it and tell them what you like or dont like about it and those kinds of videos are far easier to give titles to and of course lead to being found through searches. I know if I was to watch your videos myself regularly I would want to see only the most important things about your day although I know that is quite hard on people, I know if I was to record my life people would switch off right away, my life isnt amazing every day and I know I wouldnt have anything really good to talk about too lol but if I stuck to only showing the best moments or talking about something interesting each time then people could enjoy it.
Your niche is very hard to promote in terms of getting the word out there too but if you do what Symph has said I believe you can promote your videos well like on here, Facebook and on YouTube etc Good luck man
