I have published videos on youtube for nail care and manicure. Here are links http://www.youtube.com/watch?v=HycFvwEdcb4 http://www.youtube.com/watch?v=G8C-5FJVuew In spite of good preparation, they are not ranked well for the keywords (manicure, nails etc.) on youtube. I need some advice on how to get No. 1 ranking for a video for a particular keyword.
