In addition to creating an account on Youtube https://accounts.google.com/SignUp, you have to know that Youtube has become the second most used search engine after Google. That’s why I would recommend you the following SEO advice:
• The title: it should contain keywords from which we want to be recovered, within a logical context and with a match to the theme of the video
• Description: Including a link to our website in this section is a positive action for more visits and site popularity. The description, as its name suggests, must describe the video but it can also include some information about the company and some keyword to we want to rank.
• Tags, labels, keywords…: Implement them with keywords, as mentioned in the previous point, with coherence, not abusing with the number of those and using the relevant ones.
