A few months ago a made a YouTube channel and I am doing some 3 series. Ones about my 2 pet dogs going on adventure, another is just random videos and the other will be either Pokemon news or a minecraft series. Anyway I have at least 25 videos and some of them are really funny. But I only have 2 subscribers.
so the question I'm asking is how can I make a viral video to make me popular and get more subscribers. I need ideas.

Video's go viral when those who view them find them so amazing that they share them. Then others view them, also share, and so on and so on.

There are billions of YouTube videos out there, and everyone that posts a YouTube video, thinks their video is amazing. Fact is, most of them only really interest the person that posted the video.

If you want a video to go viral, it has to be amazing, unique, and something that will appeal to millions. Unless your dogs do something amazing, most people really won't care to watch a video of your dogs "going on an adventure". Pokemon, there are millions of videos with that subject, same as with minecraft. Unless yours is something amazing, interesting to watch, it will be like all the others out there.

Videos that go viral are videos that appeal to the majority of people out there. There's no way to know what most people will like.

Fact is, having a video go viral is about as common as winning the lottery.

Sometimes it is just luck, or something people find really stupid, or silly, or funny or amazing.

Ask all of your friends, to follow your posts, ask them to share them, and then just hope
