example.htm has 5 links. 3 are navigational links to pages within its own domain. the other 2 are external links to other websites. is the PR distributed equally (as in 20% to each link) or is there some additional weight given (more pr given to internal links or vice versa).
However, that is not to say that the anchor text boost for ranking is the same for internal and external links.
If a site is linking to me does the PR algorithm treat that pages outgoing links to external pages differently from outgoing links to internal pages?
To calculate the PageRank for a page, all of its inbound links are taken into account. These are links from within the site and links from outside the site.
PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))
That's the equation that calculates a page's PageRank. It's the original one that was published when PageRank was being developed, and it is probable that Google uses a variation of it but they aren't telling us what it is. It doesn't matter though, as this equation is good enough.
In the equation 't1 - tn' are pages linking to page A, 'C' is the number of outbound links that a page has and 'd' is a damping factor, usually set to 0.85.
does the PR algorithm treat ... differently
Hoping be useful,
Yeah, it seems that the link has been auto-edited. If somebody wants to play with the calculator, tell me and I'll sticky you the link ;).
Note: I used it a lot when I was a beginner on SEO, and I found it very useful.
