The one thing your video needs to succeed

What's the one thing your video needs to succeed?

You don't need an expensive camera, lights, microphones, music, graphics, a fancy set or hilarious jokes. 

It has to help answer someone's question.

How do I know this?  

For one, Youtube is one of the largest search engines in the world. According to Global Reach, Youtube is larger than Bing, AOL, Ask, and Yahoo combined. 

Second, thanks to Google, every time you search for something, there's usually a video, and that video has A LOT of views, even if the production value isn't great.

For example, the heating element on our dryer went out and needed to be replaced, and this video guided me through the steps to replace it:

My laptop keyboard kept locking up, and this video pointed me in the right direction.

There's no way the creators of these two videos looked at research to optimize their Search Engine Optimization. They made videos based on what they knew or problems they had solved and shared their expertise. They solved my problem, and both have 15k+ views, so it's easy to guess that they solved other people's problems too.

There was also this comment in one of the videos:

You can as well.
