When you are using different methods in order to build links on other websites you need to determine if the websites you are attempting to get your site listed on use the “nofollow†tag or not. If they do, it may still be a good idea to try to get that link there, but it is generally regarded as not the best use of time since the search engines don’t follow that link and you don’t get any increase in search engine rankings from that link.
Dofollow back links are a dream. To get this dream you should have a list of sites that allow this. These are the links that route back to your sites as well as passing the value of their Link Juice that will help increase the Page Rank.
I also found articlebase that is no follow works well after panda update as we regualr submitted to ezine and after the update our articles are not showing up for ezine (even though they were 100% unique), but the ones on articlebase are showing up on google.

Your site can be beautiful and your offers enticing, but if no eyes ever fall on them, then you will not make any money. Therefore, it’s advantageous to you to have your site ranking high and pulling targeted eyeballs! It translates directly into cash in your pocket.
