Link wheel is one of the advanced SEO concepts in the current field. A link wheel is the process of creating some new blogs or microsites on a particular topic and write a unique content of about 300 - 500 words on each of those blogs created. In that content include 1 link to one of your other blogs and one link to your targeted site.

Links are pretty common in SEO point of view as it is good for websites. The more number of quality links you have, could fetch you rank higher in the search engines. The content you write can be converted to link wheels which are likely to receive more exposure online. Thus, they can be helpful to generate more traffic to your website.

The reason why link wheels are effective is the blogs or microsites that you create are on sites like Hubpages.com, Wordpress.com, Blogger.com, Squidoo.com are popular sites and well established. Each Site possesses around PR6, PR7, PR8 and the subsequent blogs could get benefit from those.

Moreover when you include a link to each of new blogs, page rank values may traverse from one site to another, building up the value of each of our links. Note that all the links must be one-way, that is, if you create 6 blogs, site 1 links to site 2, site 2 links to site 3, site 3 links to site 4 so that the link juice is passed to all of the sites and thus form a wheel like structure. The links should not be diminished by reciprocal linking (linking site 1 to 2, and 2 to 1) which is not worthy nowadays.
