Why was my site pushed back from #4 to #90 in yahoo search?

Question

My site has been in position 4 or 5 (on page 1) in yahoo search for a while now. All of a sudden it has been pushed back to page 9! I haven't made any changes to the home page recently, can anyone give me an idea why?

Answer 1

The ranking depends on factors that they don't publish. But if a site is unchanged for awhile it gets a lower ranking.

Answer 2

I'm wondering how did you introduce it to Yahoo. By submission?

I think there were new sites so yours was a little bit old than the others or it hadn't so much clicks as before.
