Valuation of Links by PR - Discussion based on Observations

Discussions about the value of links, coming from different PR pages.

[Redge]

Hi all..

I've been hearing about this for sometime now.. Wanted to discuss it with you veterans at WebmasterWorld. Please go through the followings and reply me what you've to say on this:

# How many PR0 links are equivalent to a link from PR2,3,4,5,6,and7 links. (Assuming that no link pages have more than 30-40 outbound links)?
-(Please answer separately for each of them. i.e. A link from PR5 page is worth X no. of PR0 links)--

What do you think should be the Main-few-things to be checked or criterias while buying/building inbound links?

Please help us know more about how Google treats links from Higher PR pages (3,4,5,6) in comparison to the links from low PR pages(0,1,2).

As a rule of thumb, look at it as an exponential increase (there's obviously slightly more to it, depending on anchor text, number of other outbound links on the site / page the links coming from etc.).

1000x PR 0 links = 100x PR 1 links = 10 x PR links = 1x PR 3 links

(again, this is a rough guide, there's no real way to give an exact relation between links because it's all relative)

The full PR doesn't necessarily pass. Aside from the trivial fact that PR is shared by all the links on the page, there is also a depreciation of the link due to factors such as it's location on the page, and other factors. Two links can be on the same page and pass different amounts of PR. There is no "all things being equal" approach to the question.

Agree with martinibuster that there are too many factors to consider beyond PR.

Do you have more detail about the situation in which you'd apply this valuation or is it purely theoretical?
