I do a search and im on the 1st page. I send the link to a friend im on the 10th page. I check the next day im on the 111th page... Whats the deal? Is my position different at each datacenter? If so, why? It doesn't make sense. Every person searching the internet gets a different result when searching... That seems stupid.
It isn't un-normal to be positioned differently on each server. It just happens to everyone. They wont ALWAYS get a different result, it just depends which datacenter you get thrown at when you visit Google.com
yeah, it's probably because your site is newer and it's trying to find it's postion. Give it some time and keep building quality one way links and it will resolve itself to the higher page.
