Is this possible google dance for video?
 

Hi friends,
one month back i uploaded a video and after two days its in first of google for my keyword and two weeks later its in 16th page of google and later its again comes to 7th.

My question is, does google do a dance for ranking videos? Or did I get smacked?
Many thanks in advance for replies.

It is very much normal that the videos uploaded on Google also face competition from other videos that are also loaded and optimized with a few keywords. Hence the rankings are ever changing.
