The best backlinks from my experience follow this formula. High PR (or good metrics in Majestic, Moz, ect) + Relevance + Low Outbound Links = The Ultimate Backlink
Well you can try niche blog commenting or how about buying cheap ppc ads if what you need is traffic or targeted clients
site1 links to site2 - site2 links to site3 - site3 links to site4 - Site 4 links to your website. Simple
I have wrote a guide thread for digital points users for one of method in building backlinks and as well getting traffic while you are at it, you can find it here: DigitalPoints: How to build backlinks by social media & bookmarking.
The most effective way to build quality links to your site is to create a unique, interesting, trendy content that will guide users on how they will be benefited from your product and services then link juices will follow.
The effective techniques according to me are maintaining a blog with good and unique articles, you can also use forums , directory submission sites for backlinks (natural).
For effective backlinks, you should start building backlinks through Blogs, Articles, Bookmarking & forums. & for effective keyword ranking & traffic use SMO & Bookmarking ( Sometime classifieds even works efficiently).
