At first I even didnt believed in Angela backlinks. I tested for a site. Within 45 days the site comes top 10. So it works. The facts I found, - All the angela backlinks are not visible to Google - Some profiles are deleted - Some backlinks have no profile link url, it means we cant able to show the proof where the backlinks is located. - And this type gives temporary ranking. You have to do regularly to maintain ranking. - I used link wheel + angela method to get some more value - we are very much spamming the web 2.0 sites - some sites removed the profile section
I have noticed that for each of the sites for which I've had 150 Angela's links submitted, usually only 2 or 3 links get indexed by Google. So I'm no convinced it's worth the money or effort.
