I will analyze if "PD" appears, then "BD" and "PR" appear the changes of the Internet
Currently seoer professional and technical personnel although not many, but as long as there is a certain understanding of the relevant people know for a website PR value is very important, if Baidu appears a "BD" So for our China's website will be a great change, our countrymen may not be "PR" as the standard , but to "BD" as the standard, or both should be considered together, I believe many seoer people know that there are many people in order to improve the weight of their site, will find some high PR link to do their own site outside the chain. If there is a "BD", then the more difficult to find. This is a new chapter for China's Internet
Let me analyze Google's situation first.
First, what is Google dance?
Google dance refers to the Google search engine database once a month of large-scale upgrades. During the upgrade, new Web pages are added, invalid pages are deleted, full depth searches are performed on the site, and the algorithm may be adjusted during this period. Goolge search results show dramatic ranking fluctuations, while external links to indexed sites are also updated. The page rank, which is updated every quarter, also occurs during the Google dance period. Dance generally lasts a few days, after dance end, Google search results and the number of external links to the site to stabilize, until the next cycle of Google dance arrival.
Google Dance is the activity that Google regularly updates its index, giving people the impression that it's like dancing. In this dance process, Google's stored index has been updated, the site's ranking will change drastically, and some sites in Google's ranking overnight disappear, and some sites ranked first. Google dance usually starts that week at the end of the month, and new results can be seen in the first few days of the month, perhaps once every 36 days or 10 times a year.
To put it simply: Google dance Chinese meaning is Google Dance, that is, Google every time there will be a relatively large adjustment, during the adjustment, many pages will be the ranking of the adjustment, like dancing, so called Google Dance
Second, Google dance and PR value what is the relationship?
Google Dance once, the PR value is updated once, so when you see your Web page these days PR value changes, then explain Google these days in dance, of course, perhaps your PR although updated, but no change.
Third, how often does Google dacne?
Before 2005, Google was a one-month DACNE,PR value of one months change. Later, because of the cheating site too much, Google adjusted the algorithm, after every 3 months Dacne once. Google to adjust to let the general webmaster's attention from the PR transfer to the site itself.
How do you know if Google is dance?
1), view the change of PR value
2), through Google Dance tool query
Google Dance tool is mainly by letting you see your site in Google's several database rankings, if the rankings are inconsistent, indicating that Google is dance
3), by looking at the changes in natural search results
During the Google dance, search results may change a lot in a day, like today, I detect a word, over a few hours, may be a new sort.
Five, Google dance after the algorithm has been adjusted?
There is a certain adjustment, but the main or large scope to update its various databases
Second: I analyze the Baidu face Google in the PR value "algorithm" of frequent changes in the embarrassing situation
We all know that Baidu so far has not appeared similar to the "PR" data, so in a lot of technology, or public opinion are Google led by the nose, because Baidu in the rankings, although not entirely determined by the PR value, but, as long as the SEO have a certain understanding of people know that Site keywords in the search engine rankings are inextricably linked. This only means that everyone in order to be able to have a good ranking in search engines, painstakingly their own site hope that the PR value of their site can be improved.
But recently Google PR value has not been updated for four months, this makes Baidu's technical staff very passive, from the previous one months to update the PR to three month update PR, which technology change is already a waste of time, the so-called wool out of sheep, I think I do not want to say that everyone should know what meaning. Google intensified this time four months did not update the PR, make Baidu has to change in a related technology, therefore, Baidu in order to get rid of their passive situation, but also for our own country in the internet has a new breakthrough in the near future, whether will create their own "PR", the most likely to be named "BD ”。
