For many organizations, the main problem with changing hosts and the biggest concern is downtime. When your site is down, you may lose some visitors, some business, and some potential search engine rankings.

In fact, changing the host is just a simple operation, as long as the operation is appropriate to ensure that no downtime, but also to ensure that the search engine rankings have no impact.

When you change the current virtual host to another host, there are five main points to note:

1, check you will use the IP address:

There are some bad IP addresses on the web that are either banned or troublesome. And the last thing you want to see is your address. Unfortunately, it's one of them. A quick and easy way to check is to see if these addresses are in the Google index. Through your address search list, you will know whether the address is a bad IP or is associated with it.

2, completes the complete website backup:

Your old host should have a full site backup, and if anything fails, you can quickly restore it. (Not afraid of 10,000, only if)

3. Repeat test:

It may all look the same, but the more encouraging approach is to test all the structures and programs that are likely to break, including the database.

4, change domain name (DNS):

When you move the site to a new host, if everything works, how do you convert it? Changing the domain name is a simple matter. Through your new host provider can update your domain name, simple registration, and the new IP address of the site to update the domain name.

5, the universal waiting for the new domain name.

In other words, wait for the rest of the Internet to notice that the site has been migrated and see the corresponding new IP address for your URL. This process should not exceed 48 hours.

Dedicated host and shared host, which is better?

It has always been a matter of contention whether a dedicated host or a shared (virtual) host is more optimized for a search engine.

Dedicated host, that is, your site has a dedicated IP address of your own. It can make it easier for search engines to identify your site.

Shared host, that is, your site is sharing an IP address with other sites. Some people think that the bad behavior of other websites will implicate their website in the blacklist.

This view is not correct, the search engine will not be the entire IP address blacklist, unless the IP and share the IP site shows a typical spam activities, such as site links (link farming), link sharing (link sharing) and so on. In terms of search engine optimization, both types of hosts are suitable.
