Learning website optimization has been for some time, slowly in the work of the theory to practice, in the work of the discovery of problems, solve problems, especially some vague thoughts also slowly become clear, and, I found in the process of doing site optimization, thinking is the most important, the internet has a lot of theories, And a lot of the theories are contradictory, so many beginners, including me, always feel very confused, this time, you need to think, to practice, and, optimization has a lot of trivial work, need to do a good job, I have always believed that mouchangqing teacher's words, in the optimization of one thing to achieve the ultimate, it can achieve results, I would like to link to friendship, if the link to work to achieve the ultimate, website optimization can achieve a good result.

In the work of friendship links, how to judge each other's friendship link quality is the most difficult, but also the most important, I believe that we see a lot of information, I will not repeat, I exchange links in the process, found that many people like clinging to a certain data, such as PR value, such as snapshots, Many webmaster friends often see these two items as long as there is a do not meet the requirements, said not to exchange, and even the site does not open a look, just a shot, I can only lament, and sometimes even feel that they are a little irresponsible feeling. About the PR value and snapshots of the dialectic online also has a lot of articles, here I will not repeat, I believe that we can easily find relevant articles. Here, I would like to talk about the exchange of friendship links of a controversial phenomenon, is related to the two domain name of the friendship link, here, I talk about their own some immature ideas, let me. If there is a wrong place, also hope that the master can be a lot of guidance.

I am doing links, found that a lot of people in the release of Exchange links information, always with a sentence, two-level domain name does not, from the beginning of the total sentence of two-class domain name of the death penalty, some in the exchange process, but also in particular to the two-level domain name, think of a new station or very poor station directly in exchange for high quality two-level domain name Web site, It is also considered a concession to others. When I asked some webmaster friends, why not do two domain name, the answer is no more than two domain name does not flow ah, instability ah, weight is not high, these, here, I would like to put forward my opinion, first of all, we have to analyze the disadvantage of the level two domain name.

1. When the class two domain name is a two-level domain name under the main domain name, then when the main domain name is punished, your website will also be implicated.

2. Web site traffic ranking, the level of two domain name is attributable to the main domain name. This is because Alexa ranked by default is the top-level domain name.

3. The website of level two domain name is unstable, this main and space merchant has connection.

4. The weight is inferior to the top-level domain name.

Here, we can analyze the disadvantages above, 1th, in the process of my exchange, I found that most of the webmaster have chosen to set up their own domain name under the main domain name two, which is to the flow of credit to their own top-level domain, the 1th phenomenon at least I rarely see. And the 2nd, I think the exchange of links has little impact. After all, even the top level of the flow ranking is only as a link to exchange a non important reference factor. As for the 3rd, this is mainly to see if the site is stable, if a site has been good, access is also very stable, then this factor we can not care too much. As for the 4th, it will be explained below.

Now, we take a look at the exchange of links for the purpose of a lot of articles have been explained in detail, here, I simply quote under: 1, enhance PR. 2, improve the ranking of keywords.　3, improve the weight of the site. 4, improve visibility. 5, improve the flow. Links for traffic promotion help is very small, you can ignore.

Read the above exchange links for the purpose, we look back, there seems to be no indication that the level two domain name is not suitable for friendship links, there is no indication that the two domain name can not and a domain name to do the link ah, to Baidu, for example, Baidu's two-level domain name is included very strict, there is a long test period, however, once the Baidu included recognition, Baidu will give this two-level domain name is very high weight, as for Google, the top-level domain name and the level two domain name, in Google View, as long as there is good content, no matter what level of domain names, are also included. Visible, whether Baidu or Google, are recognized as a two-level domain name is an independent website, has a certain weight. Even some level two domain name weight than the first level of the weight of the domain name is higher. can also be a very good quality outside the chain, the same can be achieved to your site to bring a large number of web spider purposes, the same to your site's collection and ranking play a role; some of the two-level links can also bring you a certain brand effect. Some experts believe that the level two domain name is actually a top-level domain name this is not unreasonable.

Here, I would also like to put forward a lot of novice overlooked places, XXX.com and www.xxx.com In many cases, these two addresses are all the same, at this time, www.xxx.com although it is a level two domain name, but can be approximately considered a top-level domain, and the xxx.com effect is similar, but sometimes, xxx.com and www.xxx.com These two addresses are not the same, and even The previous one can not access the Web site, the author once met, at this time, www.xxx.com is a simple level two domain name.

I used to exchange a friendship link, someone else two domain name with our home exchange, I am very happy, this is because someone else is a high PR value, high weight, the second is the key word ranking, the two-level domain name is still ranked the first page.

This is my some immature idea, hope master many advice, also hope to do medical website friends can contact me, exchange links, discuss optimization, qq:1587646432 Finally, article copyright belongs to: Guangzhou Women's Hospital www.81891111.com.
