Hello BHW and malcomxar,
I think I can help here or maybe I'm just a clueless noobie. I researched my competition and found that one had a profile link, so I went to the same site and registered. About a week later, my profile link showed up. I had also registered for a free account at sheerseo and they did a free report. I looked at the report, just having a basic understanding at what I was looking at, and under the "main referrer's" I saw that profile link, it says its a ******** link and it said that it gave me a "pr boost" of 0.02 and the website was a pr0
I have bought SB and was watching the TUT's when I saw the video, describing profile building in high ranking pr websites. On top of that, I noticed in the TUT video that nofollow links were "high" lighted. So I googled firefox addon's "nofollow" and of course added it.
Now, I've been registering my profile to only pr 4+ website's. Interestingly enough, some websites profiles are nofollow, but I find the majority are ********. So much so that I just skip the nofollow websites. I think I've done a hundred or so in the last week plus I also did the tip adding another link in the signature. All of this I did not know a week ago. Now I know which are ******** and which are nofollow!
Now the cool thing about that nofollow addon is that I can see other websites that allow me to post "what are you doing". I used to post and add my site, but after the nofollow add on, I noticed the link was a nofollow. So I quickly stopped doing that non-sense, lol. I now know where to concentrate my effort/work.
Now I consider myself a noobie, i still don't know how to operate SB like a pro but I'm slowly learning and watching TUT's. I personally need major help understanding pinging and indexing my links.
Hope This Helps
