In the website construction, many times need to carry on a branch construction to the website, for example: the information station constructs the forum, actually chooses the sub domain name or the subdirectory? Many webmaster to this hesitation wandering, do not know how to choose is good. Some people say that in the optimization of the two equal, search engine and no special discrimination. It is also said that a large site to build a subdomain site to the superior applies directory, but the author here to the vast number of grassroots webmaster said is: The subdirectory is superior to the sub-directory building domain names. Why do you say that? It is not a boring charm, or from the general point of view of the webmaster.

Theoretically, whether the construction of subdirectories or the construction of subdomains, is to build a new website, so in the weight of no high or low points. But in the actual operation, both face the weight of the search engine is very different, mainly in the site optimization before and after the period:

1, subdirectories: If the construction of subdirectory sites, first of all to clearly understand whether the main station has enough weight, and then to build. If the main station does not have any weight, or by K, was blocked, this time also to go on the construction of the subdirectory site, doing things necessarily less. Therefore, the construction of subdirectory sites, the weight of the main station directly affects the weight of the subdirectory site inherited. Therefore, in the early stage of website construction, although the subdirectory site is a new station, but still will inherit to the main station part weight pros and cons. Sub-directory Sites are higher starting point, but also easier to get ranked, perhaps this is the search engine optimization "dog" bar.

2, sub-domain name: In fact, the author does not recommend the grassroots webmaster construction of the site, but still have to say its characteristics: the expansion of the site domain, similar to the company's construction subsidiary. such as Tencent, Baidu, A5 and so on large sites need to extend the business, so the construction of a large number of sub-domain names of different types of sites. Because of brand awareness, so the subdomain site is also more easily accepted, rather than as a general new site needs to be gradually rooted in the people. If you can optimize, the sub-domain name site is less than the independent top-level domain name and subdirectory site, why:

(1): Low starting point is the most serious challenge, the equivalent of a new station needs a long time to increase the weight of the optimization, unless the main station weight is particularly large, such as "***.baidu.com,**.qq.com" and so on, the search engine will give a certain weight. But most of our webmaster, there are several can be a domain name to do the popular brand? Therefore, the author suggests: Grassroots webmaster Select sub Domain name site construction, far less than select the top-level domain name or choose to inherit the master Station subdirectory site.

(2): The competitive pressure of the keywords, now all walks of life are spread over countless sites, and most of them have chosen the "WWW" Domain name to build (World Wide Web Services), and you choose their own messy sub-domain name building can be ranked into it? The competition is not very intense keyword may try, but if face high weight keyword, remove " www ", other sub-domain types of sites are difficult to line up the number, after all, search engines still need to maintain the" WWW "service Authority.

And the view of those subdirectories of the site, there is a very good performance, such as the SEO industry, "SEOwhy" is not a strong proof of it? There may be some other sub-domain sites ranking more than before, but those sites which do not have the illustrious prestige? Even a new subdomain will be given a terrible weight. In addition, from the user experience point of view, the binary network/Heguijiang (http://www.zhihuiseo.com) that the subdirectory site easier to remember also conducive to the user's confidence in the site to promote. If the content is only for personal analysis and summary, if there are different views on the exchange of research.
