The Single Best way to build high quality back-links is by getting a nice variety of links with 100% original content.
All of the methods that showcase spun content or mass linking with a single button push are complete BS.
Build MyRank is a resource that you will have to pay for. I am not someone who likes all the "pay for backlinks methods. I like my back-links nice and free and I am willing to work for them. This program really works, and the more effort you are willing to put into it the better it will be. You can use it from an automated level if you are willing to outsource the "quickie" writing jobs or completely on your own if you are willing to put a little effort into it.
How Build My Rank Works:
You write original articles and input them into the Build My Rank
system. Your articles must be 150 words or more. You can add 1 link where ever
you want with whatever anchor text you desire, and it is 1 link per 150 words.
So a 450 word article will get you 3 links.
Then Build My Rank will post this article randomly to one of its
PR1-PR8 sites. Additionally they will ping your site and add 25 social bookmark
links heading to that site. What this does is get you a link that already
carries a nice share of "Link Juice" and is indexed quickly.
Since I started using this site I never had a link that was
not indexed within two days, while other sites I acquired links from NEVER
seemed to get indexed. Of course the most important point is that all of these links are Google Panda friendly. They are 100% original from a wide variety of sources. You can't get better than that.
