Write the reason for this article, on the Internet to see a lot of people to ask this question, the website of the sub-column is to use a two-level directory or with a level two domain name good. Last year I also encountered this problem, there are a lot of people to answer, but the answer is very general, and some are mixed with a signature or outside the company. There is not much to say nonsense and theoretical knowledge. Take my example from last year's home web site encyclopedia as an example.

One, 2009.5 months

This goes back to earlier, I spent 300 yuan to buy a domain name 4140.cn finally decided to do the Web site navigation, but do not want to drift, want to make a new path to do special points. So decided to do home web site Daquan. I first collected the links of all the cities in China and then sorted them. Feel unique and everything seems smooth. But the problem arises, these cities are using the two-level domain name mode, or the use of level two directory, dilemma, find a lot of information, but also consulted SEO friends, still no satisfactory answer. Finally, to be able to remind me of the two domain name of the PR also easy to take the two domain name and other Exchange links also good optimization of difficult keywords. Decide how to use the level two domain name. So more than one on the Internet, home site encyclopedia, more than 400 municipal web site Daquan, but the main domain name included very quickly, two-class domain name included very slow, especially Baidu Google better, but the flow or see Baidu face, with time changes in the major search engine included are good.

Two, 2009.12 months problem arises

Home web site Encyclopedia has just improved, PR rose to 3, there are a lot of level two domain name also rose to PR2. Is excited to take two level domain name and others to change the link. As long as the normal station can and my PR2 two domain name change, so change very conveniently, is excited. Unprecedented internet reorganization began, my VPS to close, to submit a "white list" submitted on the white, the key is two domain name also have to submit, more critical is a VPS to submit a maximum of 602 domain name, the remaining additional a level two domain name to add money, I'll take it. If you add more than 400 level two domain names, I'm going to go bankrupt. This is the West digital, other service providers I did not go to study the valuation conditions are also very harsh, this does not criticize any service providers, should be for everyone to come out doing things are afraid of policy. After a series of technology jump, space resumption of operation, two-level domain name barely jump to run, by the major search engine punishment flow gradually decline, ranking is also gradually decline.

Three, 2010.4 months

I feel like this is not going to work, continue to complete the use of level two domain price is very high. So reluctantly changed to two level directory format, which is used as static mode. Generate all the city's first level catalogue. At first, it was feared that tens of thousands of first-level catalogs would be punished. At this time by Baidu penalty browsing volume is basically zero, to now change is not big. Google to a good immediately included a directory, the flow of small days and went up.

The last and most important summary

1) from the collection on the comparison

Two-level domain name included very slow update is also very slow, if the only consideration from this aspect, the one or two-level directory advantage is significantly higher than the two-level domain name.

2 from the weight on the home page comparison,

Whether it is from the principle of analysis or from the changes in the PR, level two directory can increase the weight of the primary domain name, two domain name will not increase the weight of the primary domain name.

3. Consider in the long run

From the long consideration, if it is to do a major stations such as large portal sites, industry portals, vertical portals, such as the vast amount of information on the site, you can choose to have a large amount of information on the channel set to two domain names.

If only do small and medium-sized sites, can rely on multiple level two directory to expand the weight of the main domain name. If you open a two-level domain name too much, it will weaken the advantage of the main station.

4 from the search engine rankings to consider

From the search rankings to consider the advantages of the domain name, in other conditions, the two-level domain name of the keywords ranked higher than level two directory.

5. Consider from maintenance

From maintenance to consider the use of two-level directory for the absolute advantage. Do not underestimate the maintenance do not overestimate their ability, perhaps very good at that time is normal, but the external environment is very few changes to my 2009 years 12 will be disastrous. Only with my blood and tears to warn you. Hope to make a stand for everyone a little help.

Written at the end of this chapter

In fact, classification is the use of level one or two directory or two domain name is a very deep SEO knowledge, I think that the study is not enough to cut through. If there is a deeper understanding of the master willing to be stingy.
