How much does Outbound links affect PR.

...which means they still got links from some other pages. Be it other domains, or just internal pages. A page cannot get PR unless someone links to it.

According to the algorithm, inbound links should increase PR, while outbound links could decrease PR. There are very few instances (e.g. reciprocal linking) when outbound links can boost your PR a little. This is not casual observation, I've seen the algorithm in action.

However as mentioned above, outbound links may be good for classification.

 

Can you show me in the algorithm where it accounts for outbound links? I've never seen it and I don't believe I've ever hard anyone claim that either.

 

Here is an excellent explanation of how pagerank works.

 

I'm very familiar with that article and the pagerank algorithm, I'm just wondering where in,

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

The part about the outbound links are?

 

The denominators C(T1)...C(Tn) account for the total number of outgoing links from the pages that give pagerank to the page in question. These pages will typically include YOUR OWN internal pages.

If your internal pages conaint too many outgoing links to EXTERNAL websites, then you are effectively giving away pagerank that otherwise could've been kept in-house, thus further boosting the pagerank of the page with PR(A).

The article has detailed explanations and plenty of examples to prove this.

 

The page itself isn't losing any PR, it'll be the same if there is 1 or a million outbound links, it's just limiting the amount it can pass on to internal or external pages.
