Link orbit is a guest blogging service or method built by expert SEO professionals. SEO companies started providing services that improve the number of quality back links. Link orbit services will bolster your website’s popularity and boost the marketing efforts.

Link wheel is the biggest technique for optimizing your website. In this,you create dozen of new blogs/websites using web 2.0 properties i.e. Squidoo, Blogger, HubPages etc on the same topic as your main website. Each of these blogs contains unique content with links that linked them to other and the final link to the site that you want to promote.

Sorry, but this is far too vague a question, and as you can see from the answers you’ve received, a simple search would have sufficed to answer the question. Please search (both the forums and via your favorite search engine), and if you’ve still got SPECIFIC questions, please feel free to repost.

In the meantime, THREAD CLOSED.
