Link building is not the most important in SEO these days. Developing an informative content with good formatting and sales input is more important than Link building. However when it comes to SEO there should be a balance between Links and contents to rank well and for longer time.
Links can be achieved by 2 broader strategies:
1. Link earning
2. Link Building
Link Earning:
Link earning depends entirely on the quality and informative nature of your website's content, (most probably Blogs). A good content will attract a lot of visitors and encourage them to share. As a result of this, your website will "earn" more links and traffic.
Link Building:
Back to good old days, Link building involves a series of link building strategies that will help you build high PR dofollow links for your website. Link building can be a painful task and these days you need some basic content writing skills to be successful.
The following are some of the more commonly use Link Building strategies:
• Social blogging
• Forum Participation
• Directory submission
• Content marketing
• Local business citations
