Application, improvement and value of pr-a little research on pr

1. Application of pr
It is best to reserve a few more high pr websites/pages, which will be easily carried out in the future?
Pr statistics on top 10 webpages with some popular keywords on google
Movie 5 ~ 6
Online movie 4 ~ 5
Sex 5
Beauty 4
Photo 5
Music 6
Mobile phone 5 ~ 6
Flash 5 ~ 6
Game 6
Does it mean that some websites with high pr can surpass these websites with popular keywords? (External connection relevance may not be considered)
2. External connections required for pr improvement
But it is really difficult to improve pr, as the game's level training starts to be able to play a higher level than your monster, the experience is very fast, but in a stage by playing strange, it is not enough to rely on opportunity (high-tech guidance)...
Pr to 4 requires 4 ~ Five external connections with pr> = 4 can be used. If the external connection pr is high, it may be less
Pr to 5 requires more than 30
Pr to 6 requires 200 ~ More than 300
Pr to 7 requires more than 1000
...... I don't know if there are tens of thousands of external connections in sina.com.cn, but pr is still 7, and tom.com is 10 thousand faster than 6 (it's useless to play more) at this time, it is necessary to connect a higher pr site. For example, internic.net (Internet Management Department) only has more than 2000 external connections to 8.
3. Time required for pr improvement
Pr to 4 generally requires 2 ~ 4 weeks
Pr to 5 generally requires 2 ~ 12 months
Pr to 6 generally takes 2 years
Pr to 7 generally takes more than 3 years
From pr to 8, these websites may be in China even if there is internet.
4. Value of pr
The value of pr is hard to say, but it also depends on where it is used. edu/gov/org pr is high but cannot sell money.
Personal site
Pr = 4 0.3 ~ More than 10 thousand RMB
Pr = 5 3 ~ More than 0.1 million RMB
Pr = 6 30 ~ More than 3 million RMB
B2B site
Pr = 4 3 ~ More than 0.1 million RMB
Pr = 5 30 ~ More than 1 million RMB
Pr = 6 300 ~ More than 10 million RMB
... Is there no B2B in China yet? Alibaba is 6
5. Postscript
What we mentioned above is that the computation in general cases may be faster if we specialize in pr.
