In the early years of the internet, links were used as a means to navigate within one website, as well as externally to like minded, or trusted sites. Because links were seen as a vote of confidence, an industry was born to show the value and trust of a site based on algorithms - known as backlinkrub aka Google in it's modern form.

Because it is assumed (correctly) that quality websites tend to link out to other quality websites, the birth of pagerank help to show the amount of links incoming to a particular web page. Now granted, volume helps, but since the power is exponential, a PR 6 web link is infinetly more powerful than 6 PR 1 links.

Knowing the big picture is half the battle, so you don't waste your time on temporary gains. Now you must begin to cultivate these links from other sources.

While many link building services exist such as http://backlinksvault.com/homepage-contextual-backlinks/ it's important to know how the processes work, as well as create them yourself in order to understand their true value.

Blog Commenting:

While many new blog posts do not have high pagerank, older more established ones are more than likely to have developed some type of PR. The beauty about blog comments is many allow you to leave a url as your name (many don't allow keywords as name though, but a link still helps regardless of anchor text used to hyperlink). The diffuclt part of this process is finding these pages that are old, yet still open for new comments. If you find a blog that does allow comments, chances are you can "harvest" or do some investigating for similar blogs (many blogging platforms will leave clues, or strings behind, and phrases). By typing in these phrases into Google you can harvest them.

Another strategy with blog commenting is reversee engineering another persons backlinks (if you know/assume they use this strategy). You can piggy back off their hard work and obtain these links by running a backlink checker software, and using the firefox plugin SEO quake, which will easily sort all their backlinks according to PageRank.

Press Releases:

Often overlooked, a quality press release submitted today, can reap great benefits in the near future. By using a service such as PRweb or other reputable wire services, many websites in your niche/ area of focus will pick up the story, linking back to your website.

As the months and years go by, these sites will most likely still exist, giving you very old, trusted links on authority websites. The risk of course is that your Press release gets picked up well, but this also means you have something newsworthy, controversial, or very interesting wrting style.

Article Submissions / Web 2.0 Posting:

There are a good amount of quality article and web 2.0 based websites. These are public networks which allow user generated content such as this one here - Wizzley. It's a win win for everyone involved. The website owner gets awesome unique content, the readers get good, valuable knowledge, and the originator/author of the content gets exposure (branding), a link back to their website(s), and even a chance to make money along with the website submitted.

A good amount of your submissions will never get a higher pagerank than 0, but since the root domains of the super established web 2.0s is high, there is a trickle down effect of trust which means you have a greater chance of obtaining a high pagerank backlink by being associated with a trusted article/web 2.0 than a new one, or a low quality one.

Creating your Own private network:

This step can be extremely costly and time consuming. It requires you buy older, established websites, add content to those domains and embed links back to your website. This then results in you having high pagerank links to your site. You will also need to have hosting with unique C class ips to get the most out of your domains. This strategy can be hit or miss if you don't backlink your own network because losing PR is a reality during the next Google update, which will diminish the value of juice / power that the sites pass on.

Because of the technical aspects and capital involved many choose to rent links from other networks such as BacklinksVault. It's recommended to always boost your backlinks with services such as http://backlinksindexer.com which can turn low quality links into more respectable ones.
