Is something updated?

Hello,

I just transferred my domain to VPS from shared hosting and did “Fetch as Google”. My keyword is “Free Classified Ads”. We know that keyword is what and how competitive.

Last night I saw my site on 1st page. I build up only few of links. Today I am seeing that site is not in 10 pages and also I don’t get any MSG from Google also. Can anyone tell what is happening ??
