On the evening of February 6, 2012, Google PR value is greatly updated, the new domain name of the website has gained 3 PR value. About changing the name of the injury please refer to the author of another article "website change domain name injury". In the beginning of the change of domain name, that is, late November last year, the author of the new domain name promotion and the old domain name of the future of the idea of a bleak, now still remember to change the domain name after that unease. With all kinds of unrest, adhere to the daily update, to maintain the quality of content requirements, daily hair outside the chain, facing an unfamiliar field, leading the new people slowly forward.

Watching the site traffic drama, and then slowly rising flow, many old friends on the site does not abandon, for a new forum is a great encouragement. Unease early in the interaction with netizens disappeared, in the PR value update, the result becomes a affirmation of the work, with the first website online, is included, get PR value, keyword ranking is as happy as before. New achievements are very gratifying, the PR value of his contribution is indispensable. Oneself is also a new person, "spot" entered the Internet this domain, then cannot leave. Like this unknown and exciting, like this rapid change, like to try to figure out the psychology of netizens, and netizens direct communication. This is a year, the feeling of personal transformation. But this is not the focus of this article. Like the previous article, send out a little whining and go back to the point. Many previous experiences have been overthrown by the experience behind them, but it is indeed an indelible experience. The internet is like this, when the sun rises, facing, may be another sunny day.

The new domain name is a new beginning, for both old and new websites. Users can find you, but for the search engine is to rediscover a new "you", and then slowly accept the "you". This time I experienced the site using the old domain name (the general sense of a domain name: www start) Six months after operation, in the absence of any jump to change the case to become a two domain name (non-www start). For a full half month, Baidu did not include a new domain name. Website operation or data talk. Two level domain name than the first level of promotion is difficult where? Look at the data first.

The original level of the domain name of February 7, 2012 PR value and Baidu display reverse link number

Now two domain name February 7, 2012 PR value and Baidu show the number of reverse understanding

Level two domain name than the first level of the reverse link higher than 4 times times, and no lack of quality outside the chain, such as Baidu Encyclopedia, soft links, but the PR value is the same. According to our understanding of the PR value of the calculation principle, the more the reverse link the higher the PR value, the higher the quality of the reverse link, the higher the PR value, then the two-class domain name so high outside the chain should be more than the original domain name PR value? (under the same conditions as the Web site architecture). The answer is no, because each up a PR value, the number of the chain will have an order of magnitude of Ascension, PR3 and PR4 between the number of the chain may not be thousands of, but tens of thousands. From the angle of the chain, and can not prove that the two-level domain name promotion must be more difficult than the first level domain name.

All along, people for the two-level domain name (not the beginning of the WWW) there is an understanding, that is, the level two domain name will be decentralized level of the weight of the domain name. But from the perspective of promotion, when the promotion of a two-level domain name, including the level two domain name Domain name (without the WWW prefix of the first-level domain name) in fact, to some extent, is also a certain degree of promotion of the effect. The most important function of the level two domain name is the extension of the first level domain name, which represents the growth of the website. For a specific function of a small web site, such as forums, the use of two domain name is not free, but the premise is a start. Change the domain name halfway, still can't afford to hurt.
