Experiences may vary but for me, all I had to do was make a video that appealed to the public.
All I had to do was figure out a topic that would get many searches.
My first somewhat "viral" video was one about an app called Verydice. I imagined that there would be many people who would want to cheat for points so I made a video targeted at those people.
Also, I recommend using something I call "semi-clickbait". What that means is that you use a title and a thumbnail that both represent the video but exaggerate what the topic is about.
For example, I made a video called "I Got Nibiru On Camera! | Proof Planet X Exists".
In the video, it was just a clip I had taken with my iPhone that I had a slight belief that it really was Nibiru. I wasn't 100% sure it was legit but I still made the title sound like I was sure about it.
In addition to the title, I used an online tool called 'Backgrounder 3' which helps make thumbnails easily. Using it, I put in a screenshot of part of the video and I put some text overlays on it that talked about what the proof was (In 5 or 6 words). But this time, I made a visually intriguing thumbnail.
That video was my fastest viewed video and I gained over 200 subscribers from it.
I feel like the trick is to base the video off current events. The Nibiru video I uploaded on September 22, which was the day before the event discussed in the video happened.
If you are a gamer, try playing games that are very popular at the time of upload. For example, a few years back, Minecraft was super popular and a video may have gotten 5,000 views. If you were to upload it today, it would most likely get under 1,000 because the game is out of style.
If you are a gamer, try going over to Twitch and see what the trending games are.
I am out of time to write this post so I'm going to leave you with that. I probably could have written another 5,000 words but I don't want to waste your time.
Good luck with your channel!
