Off course, like most youtubers say Nice catchy titles, catchy thumbnails, keywords in your titles, description and tags. Make your social media accounts on Facebook Groups, Twitter, Linkedin, Quora, Reddit, Whatsapp
, and others. I would add one more suggestion, always use Hook in your videos. For example, if people are searching for "How to bake a cake", then show the end-result in the first 10 seconds. Then start the baking tutorial. This way people will watch whole video to see how you reached the end product. The more is your watch time, the more your video will show up in homepages of many users.
