|What impact does multi-domain name resolution have on website SEO optimization?

Anyone who does SEO optimization knows what domain name resolution is. Domain name resolution refers to the use of wildcards “*” (asterisk) to make secondary domain names so that all secondary domain names point to the same IP address (record value). After the resolution is successful, any second-level domain name of the domain name .com can access your homepage. What is the impact of so many domain name resolution on website SEO optimization? In response to this problem, the following editor will introduce it to you.

1. The impact of multi-domain websites

A website corresponds to multiple domain names, and the direct impact is that the same page and the same content will appear in multiple domain names, which is equivalent to how many domain names have as many duplicate pages, which will have a serious impact on the normal inclusion and weight of the website. So, in general, if you can’t have multiple domains, avoid resolving multiple domains to the same website. So if you need to resolve multiple domain names, how can you reduce the adverse impact on SEO optimization?

1. When should you use multiple domain name resolution?

Before considering how to address the impact of multiple domain names on SEO optimization, we need to consider why we use multiple domain name resolution. One of the problems existing in the domain name market is the serious problem of domain name registration. For example, many businesses register .COM domain names. When your brand has a certain influence, interested people will register other suffix domain names.

The problem is that sometimes it is difficult for users to differentiate because only one suffix is ​​different. Therefore, in order to eliminate this problem, it is necessary to register all domain names directly at the beginning of domain name registration, while protecting trademarks.

In this case, the registered domain name is in our own hands from the beginning, so we can choose a more suitable suffix domain name to use. The rest of the domain names can be placed directly, there is no need to solve all the domain names to create unnecessary trouble for yourself. Another possibility is that you used the CN domain name at the beginning, and the COM domain name was bought recently. Not only at the SEO optimization level, but also at the operational level, we will not be allowed to directly change to a new domain name. In this case, we need to address both domains for the website.

1. The main points of multi-domain name resolution

For a multi-domain resolution website, first we need to establish a primary domain name, which we will use as a direct public domain name. Then all other domains need to be 301 redirected to the main domain. After the 301 jump is set, SEO optimization can solve the problem of weight dispersion and non-inclusion caused by page duplication. At the same time, the old domain name can be accessed directly. If the original domain name is already known by a large number of users, it cannot be replaced directly. We have to use it to keep users accessible through the original domain name.

The effect of search engines on 301 jumps is relatively slow, generally we need to keep the original domain name resolution for at least 6 months. This situation does not occur. Some websites know that a 301 redirect is required, but after the redirect is set, the old domain name is directly resolved and deleted. In this case, even if the redirect is made, the user cannot access it. The core condition for accessing a website through a domain name is that the domain name resolves to the server corresponding to the website.

For those old domain names that old users are familiar with, even after the weight transfer of 301 redirects is completed, we still need to handle this resolution problem carefully. If the original old domain name has no other purpose, it is recommended to keep the resolution.

After all, there will always be users who only remember the old domain name and do not remember the new domain name; at the same time, if you do a lot of chains, when the analysis stops, the weight of this part of the traffic is wasted. The direct weight of the new and old domain names can be transferred through 301 jumps, but the off-site weight cannot be transferred, the resolution stops, and users cannot access the website through the external link.
