IP address changed and some rankings drop

[umutege]

I changed my hosting company coz better server hardware and results (google). My website was perfectly for every queries on google but after changing company and ip address some results dropped to second page. What can i do now? These drops caused by changing ip address?

Yes, I've had this happen to me too.  I'm not sure of the technical reason for this, other then the internet being re-propogated. Everytime I relocate a website, I run into this issue.  After a month or so, everything seems to go back to normal.

They might have some signals related to IP address but in my opinion that should not have a large weight.

Your site might have a new load speed, and this is a signal for rankings as far as I know. You can use Alexa toolbar to see your domain's speed average, but it was better if you knew your previous speed, I think Google Webmaster Tools also shows you page load times, check if that increased when host changed.

I hope this helps.
