I'm not going to lie, I hate SEO. SEO= Search Engine Optimization.
It can help/hinder any website or online venture.
You have to be found and search engines are a way to find and be found by someone searching for your content.
Here's a site that I just found via Google about SEO for YouTube videos. haha.
Considering YouTube and Google are basically the same entity-- you have to learn how to use this.
What I got from this is do your research ahead of time. Go to google and research what your keywords/tags. See if you can narrow it down. Less competition=more hits. :D
Do work, my friends. Do work.
