PR duplicate link value

more than one link from a site

[hurlimann]

Is their a value in having more than one "exact link" from the same site but different pages?

I guess it might as PR is page based but
a) it may also trip filters
b) It will be discouted down in some way.

whoops! any mod care to move this to Google forum. sorry!

I don't see a problem. Lots of sites have many links to another site. I'd be more concerned about who I linked to (bad neighbourhood) or if I was heavily linking a bunch of domains together.

But will it add more value.

Say a site has PR7 on 8 pages. On these pages there is a text link to another domains url. ( a little like a site wide "designed and hosted by xxx.com ).

I would have thought algos would be set to only count one link or apply a damping factor at the very least.

[ciml]

I don't detect a damping factor. At the end of the day, you only have so much PR to share around so it's not as big a problem as you might think.

Will it add more value? Yes, but if the home page has the most PR, then it isn't going to help you a great deal (due to the log scale on the Toolbar PR chart and the way that the effect on rankings seems to work similarly).

Every link helps. I agree with ciml in that I know of no damping factor against this. The common understanding of PageRank as written in the original papers (and discussed extensively here at WebmasterWorld) is that it maps all links. I can imagine that adding a computation for screening out multiple links from one site to another could add a lot of overhead to Google's monthly processing time. Calculating PR is already a huge effort - this is why the update occurs only once per month - most of the time inbetween updates Google is just crunching numbers.
