Listicles: Listicles are a very popular content format, both as blog posts and as media (videos, images, infographics, etc.). You can create listicles that highlight your products or services – like “The 10 most innovative ways you can use (your product)” – or they can be educational, informational, or entertaining. Just remember, the lists should always be relevant to your audiences’ interests and your business niche.
I do not think this is how most people use YouTube. YouTube videos are more like blog posts, and fit more effectively into the niche of content marketing. Sure, people will comment—but they do so in a manner similar to how they comment on blog posts. They come to view and digest videos, not necessarily share their thoughts about the day. Because of this, you should approach YouTube as content marketing instead of social media marketing.
