So that means they can be also used instead nofollow ?And how now it will be better to reduce overall amount of links on site no matter are they nofollow or 302 because of new juice rules?
A 302 redirect means "“The requested resource resides (on your site) temporarily under a different URI" Improper use of it could result in a penalty, if seen as an attempt at a 302 PageRank hijack..
Great reply as usual Vagrant I tried to give you a green already but it did not allow me to do and forced me to spread to someone, which I already did. May be next time. Back to the topic- 302 means temporarily and it will not pass link authority towards certain website. However, 302 had been abused too many by webmasters around the globe before, that's why Google keep watching this kind of redirect with caution. Most of site can being penalized, a high chance even done proper with 302 anyway. That's why most are changed to use 301 to be safest instead.
i will recommend to use 301 for get same link authority on your new link. That is only the SEO friendly redirect method also said by google.
