Tags are very important, so it is easy to over-think them and worry about them too much. Actually they are quite simple to use and understand.
Use tag words and phrases that will help people to find your video. Think to yourself "what words and phrases are viewers likely to use if they are searching for my video?". For example, if your video is about Formula 1 racing then you could use tags such as "Formula 1 racing", "Lewis Hamilton", "Red Bull race team", etc etc.
What you should NOT do is use "Jake Paul", Pewdiepie", "Minecraft" and other tags that have absolutely nothing to do with the video, although being popular search parameters on YouTube. THAT would be spammy.
I hope you don't mind, but I took a quick look at your channel and would say that you need to seriously think about your titles before you even start on your tags. The titles of your videos give me no idea whatsoever of what the content is about. The YouTube search engine will pick up words from your title first, then your description, then your tags. So make sure the title really explains what the video is about.
Actually wait a second...I'm going to take a look at one of your videos...
OK - your latest one "Contagion with philofhatsandgames". I literally had no idea what I was about to watch, but then realised that Contagion is a video game and that you played it with a guy called "Philofhatsandgames".
I put the word "Contagion" into the YouTube search field and found that "Contagion gameplay" was one of the first predicted search parameters. I would recommend that you rename this "Contagion gameplay; Battle of the YouTubers" or something similar, since not many people will have heard of or be searching for philofhatsandgames.
Its all about making it easy for the YouTube search engine to find your content and catalogue it appropriately. YouTube cannot possibly know if you are referring to Contagion the game, Contagion the film, or Contagion the epidemic if you don't use words to let it know.
Hope this helps.
