When a user types his query or some keywords in Youtube search column, then Youtube first looks for the keywords, to find them in your Titles or description or Tags . If the keyword is relevant then Youtube will place your video to him in search column.
Your title describes your video, so include your keyword only once in the title column. Make sure to include the word ‘video’ in your title. Even it is good to imagine keywords in viewers prospect, else check your competitors sites .
Describe your video, and add your keywords once or twice in this column. Make sure to mention your website or blog so that it will be considered as a backlink, and an advantage for Google ranking, and even you can capture email addresses, and know who have logged into your site.
Tags are of four types: Specific, Compound, Generic, Misspellings. As Youtube generally searches for first keyword, so arrange your warning keyword in first place, and relevant keywords next. Use brainstorm to get at least ten specific keywords.
Thumbnail is the first thing viewers look in search result, it is the face of your video. Use decent and attractive image as thumbnail. Let the resolution of your thumbnail be 1280 X 720 with 16:9 ratio aspect.
