Virtual Host
Currently, many small enterprise websites use virtual hosts. Virtual Hosts use special software technologies to divide a website server into several "virtual" hosts. Each virtual host can be an independent website with an independent domain name and complete Internet server functions (WWW, FTP, email, etc ), the virtual hosts on the same host are completely independent. From the perspective of website visitors, each virtual host is exactly the same as an independent topic (a server established through server hosting and leased line Internet access.

However, if the keyword is strictly prohibited by the State, for exampleRounds of workNo matter where the website is located, it will be blocked.
Virtual Private server (VPs)
Virtual Private server (VPs) technology is used to divide a server into multiple virtual dedicated servers for high-quality services. each VPs can be assigned an independent public IP address, an independent operating system Windows/Linux, an independent ultra-large space, independent memory, independent CPU resources, independent execution programs, and independent system configuration. in addition to assigning multiple virtual hosts and unlimited enterprise mailboxes, you can also have independent server functions, install programs on your own, and restart the server on your own.
Advantages of VPs in Seo:
Similar to hosted servers, it is also flexible.
Disadvantages of VPS:
1. The virtual memory is limited. When the memory usage is a little large, an HTTP 1.1 error will occur.

Host Transfer
If you want to transfer the host service of the website, you need to find a new provider before canceling the original service provider. open an account at the new service provider to ensure that all files are correctly uploaded to the new server. after the website is running on the new server, contact your original supplier to inform the other party that the cooperation will be terminated, but ensure that they will not close your website immediately. contact your domain name registrar (may be the original host provider) to change the Domain Name Server (DNS ). the domain name server function is to resolve your domain name to an IP address that can be recognized by the computer. change the old Domain Name Server to a new one. This process takes effect for about 24-48 hours. In rare cases, it may take 72 hours. during this period, if a search engine just captures your webpage, either the website on the old IP address or the website after the new domain name resolution takes effect, in short, the website cannot be opened.
Stable support
No matter which server you choose, make sure the server runs stably.
If the website cannot be opened within a few days, it will seriously affect the keyword ranking, and may even be deleted from the index library by the search engine because the website does not exist.
