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).
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.
