For me number one rule is to create quality content thus, the rest will just follow.

Just pay attention to write a good quality content because content is the king of Google.

Building Backlinks is a strategic plan. Here are some good sources you good get links
1. Related forums
2. Web 2.0 sites
3. Blog commenting
4. Guest post
5. Article directories (last option)

Use all these sources together and do not over do only one of the above method. Just mix them up for greater results and stick to a weekly plan. It works and stop listening to SEO gurus. Try things yourself you will learn better things and get experience which is a great feeling to have.

Good Luck...

create high quality and fresh content then submit them to high pr sites. Avoid link paid, and spammed backlinks like coming from link directory sites. Avoid duplicate content!
