Newbie question about linkbuilding

I'm a beginner with respect to the linkbuilding am with some doubts that I would like to clarify. Thank you in advance for your help. It happens that I have done linkbuilding (white and black) for some sites. For example, yesterday I spent the day to comment on blogs with high PR-follow. Today, I have done tests with various tools to my site and the links are not detected. I am sure that the comments are self-aproved. Why does not appear? And the links of the hubs, lens and ezine articles are also not detected. What's happening? do these hubs, lens and articles must be indexed themselves so that the link be recognized? Thanks!Ouvir
