Hey brother,
I've checked out your Bloodborne videos and had a good look at what keywords you've used and how you've attempted to optimize them in your title, description, and tags. I can see that your target keyword is 'Bloodborne' because it's the first word in your title, first word in your tags, and it shows up 3 times in your description. This is a great start.
Thanks. I had read a thread that said open with the game name then your other tags. Guess that was wrong. Very helpful info that I will be sure to put to use.
Also, thinking of getting a new bo3 to record since my cousin sold ours. Maybe some class tips can get me on the radar.
The reason you aren't showing up in search results is because this keyword is highly competitive. Notice that when you search 'Bloodborne', many popular Bloordborne videos show up by big names including Gamespot, IGN, and even the almighty PewDiePie! As a small channel, you'll have a hard time competing for rankings for this keyword.
You've included other Bloodborne related tags like 'bloodborne walkthrough' and 'bloodborne let's play'. To rank for these, it'll help if you include these in your description as well. Nonetheless, these are pretty competitive tags. Bigger channels show up. If you type in 'bloodborne walkthrough' you'll notice that YouTube comes up with 10 auto-suggestions. Also the more auto-suggestions that show up, the more competitive the keyword. The search terms at the bottom of the list are less competitive, so these are the keywords I'd be focusing on if I were you. If none of them seem relevant to your video, then try typing in another keyword and repeating the process.
Once you've found a few less-competitive keywords, re-optimize your title. It's handy if you can get two keywords in one title. If not, just focus on nailing one that doesn't have too much competition.
Hope this helps!
