Best SEO practices for videos and YouTube

Any best practices for descriptions and other SEO for YouTube videos? There used to be a template for real estate listings that was popular back in 2016-2017 but I don’t think that’s relevant anymore lol. It basically had a guide for where to put your description (and whether it should match the MLS description if applicable), what links to add and where, what the video title/header should be, and ideas on tags, etc… Anyone have something they use that has helped them rank better on YouTube?
