I like to use only 1. The more outbound links you have, the more juice will be taken away with every outbound link.
I mix around from 1~2, not more than 2, if that is a one time web2.0 property. But of course if the web2.0 is my network, i will put different links on diferent articles in it to my money site.
What is the thing u are afraid of if you create a single link or 10 link all the back link will promote your money site only![]()
You are absolutely correct on passing link juice. The more outbound links you have on a page, them more "watered" down the link juice is.
