For instance, instead of “Company name,” try “Company name: Keyword” with your keyword being your industry, your service, your product or any term that helps define your brand and enable searchers to find you. Best practice is to approach this not as additional characters to fill with jargon about you but as a mechanism for users to come across your company organically – so put yourself in their shoes.
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.
