Create Web 2.0 Link

When you create blogs or accounts at Web 2.0 sites, not only link to your website but also link to your other web 2.0 profiles.
This will help each of the sites get more link juice to pass along to your website.
A good rule of thumb is to link Website A to Website B and then link Website B to Website C. Do not reciprocate any to maximize the SEO benefit.
One of the easiest ways to build link wheels is to simply outsource them. A great place to outsource them is LinkWheel.net. It has great starter packs and recurring packages to keep your links growing automatically.
