A domain name generally consists of English letters and Arabic numerals as well as horizontal "-", up to 67 characters (including suffixes), and the case of letters is not different, each level can not be more than 22 letters. These symbols form the prefix of the domain name, the main body and the suffix, etc., combined together to form a complete domain name.

Take a common domain name as an example. For example, domain name www.ithov.com, is composed of two parts, "Ithov" is the subject of the domain name, and the last "com" is the suffix of the domain name, represents this is a COM international domain name. And the front of the www. is the domain name ithov.com the hostname named www.

In recent years, some countries have also developed the use of the national language of the formation of domain names, such as German, French and so on. China has also begun to use Chinese domain names, but it can be expected that in China in the future, in the long term, the domain name (ie English domain name) based on English is still the mainstream.

The site uses two domain names for many reasons, I am talking about the site today because the service location changes, but to change the domain name. Just started is called China Hotel Supply and marketing network, is intended to serve hotel reservations, hotel information also includes hotel and hotel supplies suppliers trading platform. Can be done a few months later found that the location is too wide, and hotel reservations similar sites too much competition, such as Ctrip. Therefore, the final positioning only to do hotel and hotel supplies suppliers trading platform. Positioning changed, the name of course also have to change, the name modified for China Hotel supplies supply and marketing network. This must change the domain name later registered www.jdypgxw.com, certainly we will say domain name is really long, actually I also feel so.

Now the problem, changed the new domain name can not be directly canceled Ah, so did 301 redirect, and informed the Friendship Link site has been replaced. Everything according to plan, the new domain name the next day Google included more than 300, Baidu on the 10th day included the home page. is relatively smooth, gratifying is the 15th day, Baidu's main keyword Hotel supplies ranked on the effect, of course, not on the first page, but on the 2nd page, in the days after the collection has been steady growth, keyword rankings, the world rankings are also steadily growing. Google in more than 20 days when the keyword ranking also saw the effect of hotel supplies 16 Hotel Supplies Network 23. Can be said to change the domain name is very successful, Baidu ranking also often in the top 5, but also appeared a few times 1th place 2nd place. Can appear in the middle of the keyword ranking volatility problem, and this problem with two domain names have relations.

The problem appears very obvious, the new domain name included in the ranking has been rising, the old domain name has been reduced, can appear in the middle of such a strange problem, the old domain name snapshot is always faster than the new domain name fast one day, and as long as the Baidu big update when the snapshot of the new domain name drop, only a few days to adjust the ranking will come back, Strange is every , I said to the superior several times to cancel the use of the old domain name, but because a lot of the previous use of the publicity material is used in the old domain name, so inconvenient to cancel, no way to work for the company to listen to the superior, if my own site early to kill the old domain name. Moreover, the new domain name ranking is only slightly volatile and not a big problem, so let him go.

Can change the domain name to now has been full 3 months today "finally" the problem, Baidu updated today, the new domain name directly in the Baidu disappeared, and the old domain name snapshot update to July 2, the home page did not have the rank of course, is depressed, the first time since last month so big problem, As a result of the publicity materials in the exhibition changed the domain name, only the previous hair, so immediately canceled the use of the old domain name, now only the adjustment of Baidu, but only wait.

So I suggest that the site use the best not to use 2 domain names, even if you use the 301 redirect, because Baidu Processing 301 of the technology is not very ideal, wrote so much may not help you, I write this article is just a brief discussion of my experience, but also hope to know more SEO experts, Welcome to the Exchange I QQ281826888.
