There are many SEO techniques that play an important role in optimizing your website. I am well aware with the SEO techniques, but some of the techniques that I usually prefer are Off Page techniques and they are:
Article submission
Guest Post
Blogging
Forum Commenting
Blog Commenting
Infographs, etc
There are other On Page factors as well that I have worked upon as it is important to follow both the aspects of Search engine optimization.
