Why do my Youtube videos get no views?

I used to actually get more views, but now I barely get 10 views on a video. I upload MW3, Black Ops 2, and I recently started uploading Minecraft and Happy Wheels to have a variety. I use lots of tags and I usually have HD videos. I think I use good thumbnails too. Any advice?

With so much content out there it is hard to get videos noticed now adays, there's so many that are so similar, make sure your tags are very precise, Your playing MW3 remember this game is getting older now more people are searching for Ghosts or blackops 2, You have nice thumbnails, maybe get a new profile pic, Remember the videos don't just "get popular" share them on social media sites facebook, twitter, friends, family.

You have 700 subscribers that's excellent for 6k views, ill subscribe and check out your content thanks for sharing your channel.
