Music promo video; purpose and success criteria

How can we measure the success criteria of a music promo video?

• How many youtube hits it gets
• word of mouth
• newspaper/articles/reports
• How many times it gets on television
• amount of publicity
• downloads legal/illegal
• charts
• CD sales
• VMA awards

It is worth noting that there has been a massive switch in the importance of youtube from television channels such as MTV who play more tv series than music.
Now most viewing of msuic videos now appears to be online.
