SEO ranking factors

[PeterSEO]

Hello I am reading SEO ranking factor (very good informations)

and I want to ask: what does it mean:

of linking C bloks to page

I think that: how many(#) links from the same server (C block) links to your

homepage or some pages of your web...

of linking IP adresses to page

how many web links are going to my web and every links are from another server.

if I understand it good, it is no different between, if you have links from

webpages in one server (one C block) or

from webpages on another servers as your web is,  because both correlation is  0.25...

THX

Could anybody expalin me, what does it mean:  # of External Links w/ Partial Match Anchor Text http://www.seomoz.org/article/search-ranking-factors#metrics-5

The number of external links and all these external links contain partial match anchor text from my query:

(I am finding in Google "tennis" and see in SERP domain www.usta.com. # of External Links w/ Partial Match Anchor Text: tells me the number how many external links contain partial match anchor text "play tennis, tennis school, tennis info..."? )

if I understand it good, it is no different between, if you have links from

webpages in one server (one C block) or

from webpages on another servers as your web is,  because both correlation is  0.25

This is the big difference - if you have a vast majority of links from one C-Block or one IP address, both has a negative impact in the same amount. Links should come from a wide variety of different IPs on different c-blocks

OK I understand, that this is bad when you have all links from on C-block, but why # of linking C bloks to page - have correlation 0.25 and: # of linking IP addresses to page - have correlation 0.25.

I think that correlation: # of linking C block should by less than correlation: # of linking IP addresses.

Thanks for the link - I read this before though.

Well, the correlation data is the result of a high amount of websites that have been analyzed and how their rankings were positely/negatively related to a certain dimension, in this case number of different c-blocks/IPs linking.

Even though I agree with you that a more diverse IP profile should have more impact than diversity in terms of c-blocks, it might just be that websites having a high diversity of IPs also have more websites from different c-blocks linking and vice versa.

Just my thoughts...
