The second-level domain name can consolidate the status of the main domain name (also known as the first-level domain name or top-level domain name). I believe many people who do SEO have heard of this concept, and it is also an unchanging truth in the search optimization industry. No academic can guarantee that there will be no opponents, but there are also many people who confuse the two concepts of secondary domain names and primary domain names. Taking this opportunity, Xiao Li is just describing and analyzing how to transfer search engine weight through domain name optimization. . I believe that if you understand these basic conceptual issues, your ideas will coexist with the truth!
1. Second-level domain name and primary domain name
A domain name consists of a domain name subject and a domain name suffix. The subject is the custom name we used when registering the domain name. Take an example to illustrate the domain name format: www.admin5.com , the domain name subject is: admin5, the primary domain name is: admin5.com, and the secondary domain name is: bbs.admin5.com. As for the primary domain name with www, strictly speaking, it is a secondary domain name. A type of domain name is just a "common domain name" formed by long-term user operating habits. What is more special is that the domain name with www has been accepted and recognized by the majority of users and webmasters as the main domain name. However, as SEO personnel, we should distinguish the respective characteristics and advantages and disadvantages of the main domain name, secondary domain name and sub-directory, so as to help us better exert the domain name inclusion effect!
2. What is the domain name inclusion effect?
Common second-level domain names include: www, bbs, blog, fourm, club, etc. As for why a good website should use a second-level domain name? These questions are generally asked by small and medium-sized webmasters. If the website size is small, one should be used. Virtual space can completely accommodate website programs. For example, large community portals involve a wide range of website content. How to classify and manage it is a big problem. Using second-level domain names, you can freely separate website spaces to different IP addresses to achieve hierarchical management and facilitate maintenance. Physical isolation is used to prevent the occurrence of website security compromise. The second-level domain name URL includes the URL string of the main domain name. When we do website SEO optimization, we often use the domain command for analysis. The external links of the second-level domain name previously released by the optimizer all include the URL link of the main domain name, and the important ones are Each secondary domain name link will have an impact on the primary domain name. From an SEO perspective, each second-level domain name is equivalent to a relatively independent website. The long-term promotion work for the second-level domain name is actually to continuously increase the weight of the main domain name.
3. Which is better, subdirectory or second-level domain name?
It is not difficult to analyze this problem from an SEO perspective. If the weight of the www secondary domain name is transferred to the main domain name through 301 domain name redirection, and the SEO focus will be on the ranking optimization of the main domain name in the future. So it is no longer important as to which subdirectory or second-level domain name is more conducive to SEO optimization, because no matter how you do it, it will directly or indirectly increase the weight of the main site. All second-level domain names have the same level of treatment. However, the first-level domain name (primary domain name) can inherit the weight of all second-level domain names. This is the unique natural advantage of the top-level domain name, and the default weight of the top-level domain name for search engines is slightly higher than that of the second-level domain name. It can be seen that the new website is online The most important thing is SEO domain name optimization, which will be the Roman road that determines the direction of later maintenance of your website.
Summary: Website SEO optimization is not limited to updating content and publishing external links. As long as you observe and analyze it carefully, you will find something. Regarding SEO domain name optimization, it is not limited to the above three or two methods. Domain name methods are diverse and can be optimized simultaneously. Domain name optimization also includes centralized jump, form return, HTTP transfer, URL structure, domain name guidance, domain name level, domain name Pan-analytics, as well as the SEO effects produced by the above-mentioned domain names, in fact, all SEO optimization methods deliver weight through domain name transfer. As long as you pave this bridge for search engine crawlers, I believe it will give you a good review.
In view of the personal opinions that will gradually be analyzed in detail by everyone in the future, if there is an opposing school of thought, please come up with actual data and give a nod. Don’t exclude and refute other people’s opinions without any basis! In fact, I also like to argue fiercely with friends who have strong opinions. Only by gathering the collective knowledge of the industry to expand personal knowledge can we better achieve the ultimate goal of website ranking optimization!
