Value of a link from domains of different PageRank?

[colourbleu]

I need to find out the value of a link.

Say for example I have 100 outbound links on a PR1 domain. the links are no more than 2 clicks away from the homepage. the value of each link on this site say is worth say .01 Prollars (pr currency).

In order to spread the same value (.01 Prollars) as one link on the above but on a domain that has a PR2, how many outbound links can I put so that each one has a value of (.01 Prollars).

likewise on a PR3 domain how many links can I put on it so that each one has a value of (.01 Prollars)
etc. etc for all PR1-10

So I need to determine values of links from a domain so I can fill in the blanks below:

PR1 / 100 Links : each with a value of .01 Prollars
PR2 /? Links : each with a value of .01 Prollars
PR3 /? Links : each with a value of .01 Prollars
PR4 /? Links : each with a value of .01 Prollars
PR5 /? Links : each with a value of .01 Prollars
PR6 /? Links : each with a value of .01 Prollars
PR7 /? Links : each with a value of .01 Prollars
PR8 /? Links : each with a value of .01 Prollars
PR9 /? Links : each with a value of .01 Prollars
PR10 /? Links : each with a value of .01 Prollars

Many thanks in advance

1. Pr is worthless
2. I do not understand "pr of the domain" and "2 clicks away from the homepage"

3. from what i understand, i can give you this hint:

pr4 link: $20/month (10 links on page)
pr5 link: $40

...

pr3 link: $10
pr2 link: $5
pr1 link: $2 --> 100 outgoings --> $0.2

==> so i double the price for each pr-point increase.

your table would look like:

PR1 / 100 Links : each with a value of .01 Prollars
PR2 /200 Links : each with a value of .01 Prollars
PR3 / 400 Links : each with a value of .01 Prollars
PR4 /800 Links : each with a value of .01 Prollars
PR5 /1600 Links : each with a value of .01 Prollars
PR6 /3200 Links : each with a value of .01 Prollars
PR7 /6400 Links : each with a value of .01 Prollars
PR8 /12800 Links : each with a value of .01 Prollars
PR9 /25600 Links : each with a value of .01 Prollars
PR10 /51200 Links : each with a value of .01 Prollars

Apart from whether links should be valued by PageRank, which is very questionable...

...the value of each link on this site...

The question isn't properly framed. PR is page specific... not site specific.

so i double the price for each pr-point increase.

The pricing of the marketplace aside, the PageRank scale is not linear. It's logarithmic. So its "value" should properly increase exponentially for each PR point... it's commonly assumed with a base of around 8.

Then, roughly, it is distributed proportionally among the number of outgoing links on a page. When those links cycle PR back to other pages on a site, the considerations get more complex, but this is a rough way to look at it.

I have to wonder if a link from a page with related material might be of more value than one of greater page rank. Now I realize a PR 8 is probably going to help more than a PR2 but still with pages closer in page rank you would think other things would be considered.

Links do have more value than PR transfer only - a targeted topic means a lot to your ranking in the search results, even if you don't see the green bar move at all.

One factor people think about with PR is this: what, if anything, has changed since the original equation was published? Google spokespeople say that PR calculation is still "similar" to the original, but it's not "the same."

One factor that may have changed is that some link locations on the page may be weighted as more or less important for the PR vote. That's just a guess, because it can be hard to separate out the the affect of anchor text from "purely" PR, but something in the algo makes a link in the body content more powerful than a link in the footer, apparently even with the identical anchor text.

I don't think you're going to answer this question about "the" PR value of a link unless you know what has changed in Google's calculation. You can figure out something general according to the original equation - a "rule of thumb". But for any precision, you might want to follow the PR calculation through more than one single iteration - factor in something for how fast the loop back to the original linking page gets closed. In other words, can you follow just one link and return to the original linking page, or is the shortest path back around the web going to be 3 clicks long, 5 clicks long, etc.

And commenting once more on annej's post, the "value" of a link altogether, not just PR value, can have a whole lot to do with the content of the linking page, even beyond the anchor text.

Would this be just as true with internal links on a site? I've been putting links to related pages on my site in the side navigatioin but have wondered about putting them within the article.

[tedster]

I haven't tested it, annej, but my hunch is that content area link would be stronger for internal links, too. And I'll bet you get more clicks from a link in the content area, no matter what the algo does with it!

Agreed.
And, IF the link is relevant AND your site is good, then visitors will spend more time within your site, will read more pages, will bookmark more often...

Instead, one can place an obscure delusory link on the feet of all pages of an unrelated site. Few people would click on it; and, of those few, most would click back or would just close the window right away.

Should (would) Google's algo reward both links the same way?

[colourbleu]

for my needs the post by rocco is I think suffecient if that is a sort of ball park value of the outbound links for PR pages.
I must say its quite interesting to see the breakdown. I will try and analyze it against what i see with my own sites. I have one site that got a pr5 from pr0 (new site) in the latest shakedown. that site had 450 inbound links one of which is on a pr 8 trusted domain. so by looking at the number of other links on that page I will compare it to see how that figures.

thanks for all the input.
