I just had this thought while I was analyzing Angela's profile links. If you guys noticed, Angela was promoting this article: http://www.goarticles.com/cgi-bin/showa.cgi?C=1151743 under the search term "backlinks". A few days ago I noticed the article was ranked #2 under "backlinks" search term on Google and Yahoo. However, it suddenly disappear from top 10 from Google. So it makes me think the page was dropped down due to spamming, or it is fluctuating because new Google's feature: Caffeine. I have to admit, Angela footprints are very obvious. Most of her profile pages uses the same user name which is very foolish. Moreover, she added no content on those profiles. They do not look as natural profile page having 2 spammy links. So if I want to use the same method of promotion. Should I use an intermediary page as Angela did or just put a direct link to my money sites? The point is to avoid any penalization. Have you had success using profile links as Angela? What would you do in this case?
