June 6 is a very popular Dragon Boat Festival in China, remember in a Sino-Korean world Cultural heritage battle after China failed, the Dragon Boat Festival began by the State Council as a statutory holiday in China and a holiday three days. Although the length of the holiday is not an indication of the degree of emphasis on this culture, at least it has begun to pay attention. I don't mean anything else. Just feeling and hair, to a stationmaster actually did not have a holiday, a few days ago in A5 see Shanghan introduced a concept of signal-to-noise ratio, there would have been a vague concept, after reading the article on the concept of a clearer understanding.

Signal-to-noise ratio means that the page is useful information on the total number of pages of the proportion of words, said search engine has to deal with the process of noise, that means grasping the main idea of the article. See here you may be puzzled, the article title is not the top level domain name and the two-level domain name between the weight relationship, how to introduce this came. In fact, I just want to say that there are some basic SEO knowledge we do not understand, but every day in the actual operation, practice of True truth is true, but if there is no theoretical basis, you will be around a large circle to find yourself back to the original point, theory and practice must be parallel, which is why I want to introduce domain name related knowledge of the reasons, Because I found a lot of beginners can not correctly distinguish between the top-level domain name and level two domain name.

Whether the domain name with www is the top-level domain name

Of course not. Only you registered in the Domain name registrar without any prefix of the domain name is the top-level domain name, any other with a prefix is a level two domain name. There is also a problem, such as com.cn, net.cn, com.hk and local domain names such domain names belong to the top-level domain? For this I personally think, strictly speaking, they really belong to level two domain name, but because these two domain name has its particularity, so take out as the top-level domain name to sell to us alone. How to clarify the relationship between these domain names, I think we can use the Chinese administrative division to do metaphor, China's first level of administrative division is "province", can be likened to a top-level domain name, it is the highest administrative region, the province below the city (the city is equivalent to the two domain name), under normal circumstances, the province is the highest administrative region, but Beijing, Shanghai is the highest administrative region (this is like the com.cn domain name), that is, the city replaced the status of the province, the exercise of the province to take the benefit, then you say Beijing Shanghai is the province or the city? So we should be able to understand the top-level domain name and the relationship between the level two domain name, can also correctly distinguish between the top-level domain name and level two domain name.

The weight of each level two domain name is different

This question I have for Baidu and everyone to talk about their views, the two-level domain name between the weights are different, then they are the high and low order, the individual think should be as follows: Top domain name is certainly the highest, Then of course is com.cn this kind of special domain name, then is the WWW level two domain name, finally is the ordinary level two domain name. This is my personal experience, and if you don't believe or want to verify, I can provide you with a method that is you at the same time to resolve the WWW and another ordinary two-level domain name to a website, of course, only to resolve the 2 domain names, the other two-level domain name and the main domain name are stopped parsing, then only 2 domain names can open the site, And you only update the content of the site and not for any domain name to do outside the chain of construction, you see Baidu will be priority to include which domain name will know.

Because of limited personal ability, the article organization is not tight also please put forward valuable advice, of course, I also try to let you webmaster friends can see my article when some harvest.
