Thanks hooperman for help

 

any one have other idea

 

I am not an expert, but I heard that as oppose to PR, SERP can change daily.

 

Also your site PR can be 0 and it still be in no 1 position in the ses.

 

and of course your site can be in sandbox now. When you started your site, its got bonus of a new site. But then it ends, and sandbox starts.
