Hard to find anything bout that topic.
Perhaps you know some ressources? Anything? Someone that did some reliable studies where he tested links from NOFOLLOW sources? AND waited 30 days. AND did nothing else to a site during that timeframe?
I havent hat time to do a thorough one on this ( you know, where I only test 2 pages or so
caue I am lazy) , but my other concurrent tests are showing that 19/20 cases NF dont pass NOTHING at all.
but in 1/20 it passes some juice...
and, to get somewhat of ranking if, for example you are using Blogcomments as your only linking sources (some ex client kindly did "negative SEO" for this study. dick - thought he could skip my payment... ) , you need A TON of them to even move NO comp keywords to some spaces...
As I dont want to warm up the discussion IF they help or not, I ask if you know some sites that did some studies on this..
