I was checking some blog entries here and found that all the outgoing links there in content are nofollow. Are they all nofollow by default, or there are any algorithm in place (like, signature links)?
You can search for plugins to do the same. If you have wordpress blog then go to their plugin website and search for "nofollow links" and you will find plenty of plugins for this.
link blog in this forum or other sir? if yes... by default signature in this forum is nofollow and only premium member is dofollow... (i'm check with ads on firefox nodofollow) for detail you can check article nofollow links in here http://forums.digitalpoint.com/showthread.php?t=2221026
That I aware of. Well, I thought it was only the forum part of DP. Surely misinterpreted the "All links on this site" part. @freshgreenlove, thanks pal.
