i have recently upgrated my hosting ip shared to dedicated, in this case google traffic will effect i lost somethin ?
Did you change the country of hosting ? if yes, so it might effect. Lets say you were hosten in the US and now you moved to host in India, so your US ranking might be effected.
Your google result more depend upon the hosting of your site. If you host your site from US then your site get good ranking in US. In this case if you change the hosting of your site then your ranking and traffic will be effect.
I don't think that you are going to lose anything after changing the shared hosting to dedicated one. Yes it might affect your site, if you have changed the hosting from one country to another.
It might have some impact, but not so much. Just continue on your off page optimization and your dropped SERP will back to normal.
i have same hosting service that i was used before, just i upgrated my ip to dedicated on same hosting server am still at (Dallas, TX, US) server.
Well, if the update causes a downtime error, that would surely affect your traffic coming from google. But other than that, I couldn't think of any. I don't think so. It's a factor but not totally the most significant one in terms of ranking geographically. Google satisfies a lot of factors before coming up with a ranking for a site. And if you are telling us that acquiring a hosting service based in US would help rank a site in same location, what more can backlinks coming from sites hosted in the same location will do with your rankings? Take note, google counts backlinks greater than any other factors.
If you still host with the same company and just changed hosting plan and IP it will have no effect whatsoever. I changed my website from shared to VPS hosting and then back within two months and there was no ranking flactuations at all.
