How do I get quality back links?

You can get quality backlinks from Web 2.0, blogs, forums, directories, and many more that can be found online. Some internet companies do provide such services. However, you need to be prudent of the companies you will be using. Secondly, your site(s) may be de-indexed by google if you are not sure of what you are doing.

As a start, you can create a blog and concentrate on the content creation on your main blog, and also post blog comments on the related blogs on the niche you are working, so as to create back links to your main blog. This method is free and you can just spend 20 to 30 minutes a day just by posting comments.

Once you have gotten some success, you can explore other linking strategy such as creating squidoo lens, hubpages to drive traffic back to your main blog too. Focus on the blog commenting first before exploring other strategies.
