By reaching out to bloggers in your niche and offering them high quality and free content in exchange for anchor text links back to your website is a very effective and efficient SEO method. Having do-follow links from high PR blogs is way worth more than having links from article directories. You can also generate quite a lot of business just from guest posting on the popular blogs and having a good call to action.
