Google Says : PageRank Dilution Through A 301 Redirect Is A Myth

PageRank Dilution Through A 301 Redirect Is A Myth

“The amount of PageRank that dissipates through a 301 is currently identical to the amount of PageRank that dissipates through a link.” So the myth that you should not use 301 redirects because it will dissipate more PageRank than using a normal link is ( currently ) not valid.

However using 302 temporary redirects will not pass any page rank at all.
