I know a lot of people use web2.0-s as buffers between their money site and spam/PBN links. Let's say : a.) I send a PBN PR 3 link straight to my money site. b.) I send a PBN PR 3 link to web2.0 that has a link to my money site. How much of a boost should I expect from the option b compared to option a? Let's say with option a I get 100% link juice but how much would I get with option b? Thank you!
