A link wheel is an SEO technique utilizing multiple Web 2.0 blogging platforms to interlink articles, that is one of the most effective ways to target a specific keyword and get to the first page on Google.
You can increase the power of your link wheel by using social bookmarking websites.
This is a very effective strategy because you’ll be getting a lot of backlinks to your site which will help you rank easily in search engines.
The only downside of this strategy is, it takes a LOT of time. Why? because you need to make unique articles to each of your web 2.0 websites and you also need to create unique accounts for your social networking websites.
