What are link wheels?
For those of you who are hearing it for the first time, let me tell you, that link wheels are a series of web 2.0 properties which link to your landing page (that is your main website or blog) and to other properties in your link wheel. It is called so because the series of properties are linking to one another and each of them to the landing page and this forms a wheel. Linking directly to your landing page is also a good option, but direct links are very weak and take very little effect on your page rank. Google finds a wheel of links interconnected much more powerful and generates great effect on your main landing page.Link Wheels
