Our company is very interested in transferring our high-ranking websites from Godaddy to an alternative hosting service (ie, Amazon Cloud) without affecting their Google search result positions. However, our organization has already tried several transfers of this nature, with mixed results. Though we're following all the necessary common sense procedures for a "safe" transfer (no downtime, same domain, same content, same page URLs, etc.), sometimes our sites will suffer greatly diminished Google rankings for seemingly inadvertent reasons. 1.) SUCCESSFUL: Transfer a site from a Godaddy "shared hosting" plan to a Godaddy "managed server" By this, I mean that we managed to successfully transfer a website (ranking on the 1st page for the keyword "games") from a Godaddy shared hosting plan to a managed server without any Google penalty. We changed the DNS, kept the registrar the same (Godaddy), and also (obviously) changed the file host / IP address. 2.) SUCCESSFUL: Transfer of several sites from one Godaddy "shared hosting plan" to another Godaddy "shared hosting plan" (we have several of them) under the SAME Godaddy account. The sites incurred no loss of Google search position. 3.) FAILURE: Transferring several sites from a Godaddy "shared hosting plan" on account A to an IDENTICAL Godaddy "shared hosting plan" on account B Once (for organizational purposes), we transferred a group of our domains from one Godaddy account to another (seemingly identical) Godaddy account / hosting plan, and the results were catastrophic! All these sites (1st page results on Google for keywords like "guitar tuner" and "bass tuner") were completely removed from any Google search results for prominent keywords. After some time, they began to reappear for these keywords, but never fully recovered to their once prominent positions. What is particularly puzzling is when you contrast this experience with #2. As far as we can tell, the only difference between these two transfers is one involved a different Godaddy account, and the other was under the same account. 4.) FAILURE: Transferring a site from a Godaddy "shared hosting plan" to the AWS cloud service We recently tried transferring one of our high-ranking sites (one again, a first page result) to the AWS cloud, and the site suffered a moderate drop in Google search position. We gave it a few months, and after it didn't recover, we switched it back to Godaddy. Since then, it has yet to fully recover. ... We're all professionals here, but as far as we can tell, no online resources have been able to explain this...so I would GREATLY appreciate any helpful information that some generous soul on the internet could provide!
A tip i can give you is to keep the same nameservers. i know this is not possible with shared websites but if the website is hosted on a vps or dedicasted machine then make sure the nameservers are identical for example ns1.digitalpoint.com and ns2.digitalpoint.com is retained on the new server in which you are moving too.
