let's say i have site a with a current page rank of 3 and site b with a page rank of 0. what i want to know is if it's possible to use 301 redirect from site a to b to transfer the page rank?
You would more than likely not see the PR update on the toolbar until the next update, but the SERPs would be effected immediatly
yes, even I say it should and it might work, but try using domain A that is PR3 right now if you can and if u care about links. Also, the better way would be to try and email all people linking to you to change the links, but then even that has flaws, a lot of people might not do it or may even remove the link altogether. Your choice...I wouldn't do it..!!
