In the process of doing site optimization, level two directory and level two domain name are often used. Under the main domain name, build two level directory, the theme and the main website related, rich content, can directly improve keyword ranking, promote the main domain weight. The same keywords, competitors if the internal page, and you are the directory page, then you have the same weight in the site, your table of contents pages than others in the dominant page. Keyword optimization in the case of relatively high difficulty, you can build multi-layer, and level two directory is a principle, are all over a level of promotion, improve the overall weight of the site. The two-level domain name can also help the primary domain rank, just not like the two directory as a direct help, many people think I built a two-level domain name can promote the main domain ranking, this is a misunderstanding, and about such a lot of misunderstanding, to see the site level two domain name have to say some things.
1, the level two domain name and the main domain name Association is very big
A lot of people think that the two domain name is related to the main domain is very large, in fact, not much association, according to Baidu, two domain name has its own domain name has its own station, is a completely independent site, has its own separate content, a separate judge. But to say that there is absolutely no connection may be too absolute, why many people will find the weight of the station to buy a two-level domain name to do the site? Why does Baidu crack down on the sale of two-level domain names or directories for cheating stations? There are many reasons for this, but there is no denying that there are some related, but in my opinion, this association is very small.
2, the level two domain name will disperse the main domain name weight
About the second level of two will be decentralized weight, loss weight of the argument wood-wood seo is a lip, this weight how dispersed? You build a class two domain name, the main domain weight will lose part? Do not say the weight of this thing is not official, Baidu for the site of a comprehensive scoring value will not be with the opening of the domain name and reduce, If so, wouldn't it be a Web site to create a directory, do the inside page will hurt the main domain?
3, level Two will inherit the weight of the primary domain
This is often seen, a lot of people feel that the two domain name will inherit the weight of the primary domain, so the weight of the main domain after the high resolution of a two-level domain name, want to take shortcuts, the results Shiri. The front also said that the two-level domain name to do the site is a separate station, not from the main domain to get what, to do this station, but also need to adhere to the step-by-step to do it down. Some people will ask, that why Baidu's some two domain names, such as: library, know, encyclopedia and so how weight is so high? This is the Baidu step-by-Step optimization accumulation out, is not the original analysis out is this result, and you just see done well, that Baidu domain name under the other two domain name, you have to see?
4. Shell
The level two domain name is completely an independent website, but the website needs to have the content, may do all different content, also may do similar content, or to the main domain next one key content expansion. But do not put an empty shell in that daydream, two domain name also needs the content of the supply, but also the need for high-quality content, how to optimize on how to optimize, there is no shortcut to go.
5, two level domain name is done, the main domain must be good
Class two domain name is done, the main domain will be good? completely irrelevant two content. A lot of site level two domain name is much better than the main domain, these two are not related, so want to two level domain name to promote the main domain to link them up, in the two level domain name to access the primary domain. Take Baidu, its two-level domain name and the main domain and other domain names are interrelated, promote each other, each domain name is independent, but can switch to each other and promote each other. So you want your level two domain and level two to promote the ranking of the primary domain, you need to make them a reasonable association, but not pile anchor text stack links.
6, the main domain under the two-level domain name weight must be lower than the primary domain
In front of said, this question is obvious, why two level of domain name weight must be lower than the primary domain? As long as you do well, the level two domain name can exceed the primary domain. Must your son be poorer than you?
Said so many two domain name misunderstanding, let us take an example to see, the level two directory is like a country's each province, and the level two domain name is equivalent to this country's subsidiary country, a country's various provinces rise to become rich can directly promote the development of the country. And the subordinate countries become cattle, this is not necessarily, you have a good relationship between, mutual benefit, may drive your development, but it may also be no longer attached to you, or even more than you.
All in all, level two domain name and level Two directory are all can be used to help the main website progress, but to the level two domain name help, first of all need to put this two-level domain name and the primary domain associated, and to do a good job of two domain name construction and optimization, although the two domain name will not disperse the main domain weight, but will not inherit weight, A useless two-level domain name you have a good relationship with the main domain does not play much role. In addition, wood-wood seo suggestions in your content is not strong enough to become a stand-alone site, or use the form of level two, in search engines there will be better performance.
