Words are great.
If you're answering any questions in your videos that are commonly asked, the initial question can be a good one. I make educational videos, so I usually answer a few commonly asked questions or something relating to that. Also, what you include in your description is very important, too. Include your sources and maybe even the name of the article so people are more likely to find you if that's something they're looking for. Google Trends is your friend!
