Don't Laugh --- too loud

Hey WF's.
Ok. This is probably a newbie question and even if I'm a self-taught SEO I can't resist the temptation to ask. I've been searching high and low, also in this forum, but just can't seem to find a solid answer.

Topic: profile linking.

I'm very versatile in my link approach and small part of my strategy includes profile building and blog commenting. Ones in a while I come across a blog where I just don't stand a chance to make a decent answer in that the topic is so far away from my brain capacity that I give up outright. But I do want the link (hehe - logic here is to avoid only focusing on BLs in my niche of course).

So the question, if you build a profile, with URL link, even with a sig, will the bots pick this up? When your profile is on public display, no problem of course, but what about fora where member details are only available upon logon? Will the bots go beyond the logon to pick the profile (link) or will them simply pass.

To me this is pretty important in that if the bots can't pick up the detail why bother planting profiles on member logged fora?



Cheers,
