Lets say I get a link from a PR4 site, would more PR get passed to me if that site had less outgoing links or does this not have any factor on how much his PR will affect my PR.
You got it spot on.. Lesser the number of outgoing links from the "backlink page" will help you get more PR.
is pr site cateogry relevent with your?. if yes this is good factor with outbound links number. But pr4 is not big so you must find highest backlinks. Regards, Mustafa
Both max pain and Mustafa are correct. In addition, make sure this incoming link do not bears a rel='external nofollow' attribute in the anchor link or else no PR value will be passed
If I get a backlink from a PR5 directory and I ahve certain links on my homepage whether these links will share my PR Whether I will lose Pr because of this
