My first impression from your channel is that video titles feel very forced. BEST X 2016 is bait at best, unclickable at worst. As for four exclamation marks after the title of an update video, or bland titles in the name of SEO, it just isn't working. At this point, I haven't clicked on any of your videos, and I already want to leave the channel. Given that your thumbnails are serviceable, but mediocre at best, you've got a while to go. SEO is all well and good, but it just feels like you're trying waaaaaaaay too hard. Take a brief look at my channel. Succinct, no excess capital letters or exclamation marks, but still appealing to click on. That's really what you should address first before I even take a look at your videos.
