Quality back-links are the key to any site ranking well in the search engine results pages. The search engines (especially Google) look very favorably upon and web page that has a bunch of other web pages linking to it. There are many good reasons for this, not the least of which is that it is very difficult to gain these quality links back to your site.
The search engines have gotten very good at identifying links coming from so-called "bad neighborhoods" like link-farms and the like. Internet marketers have found it very difficult to generate a significant number of quality links without spending months working on article marketing and Squidoo lenses.
Currently, the best options for getting quality links are directory submissions and buying text links from sites with high page rank. This method has proven to be very expensive and difficult to maintain. That's where the Linkvana service comes in. Linkvana went live in late 2007 and decided to only accept 300 members. The creators had to limit the number of members in order to preserve the integrity of the program and the back-links being generated.
The way that Linkvana works is by allowing members to create blog posts that are posted on high-quality blogs with Page ranks of 2 and up. Each post can contain one link to any page of your choosing, and the member can even control the exact anchor text of the link. This is a very important and valuable feature, as it allows members to focus on optimal keywords in order to maximize traffic from the search engines. Linkvana allows members an unlimited number of posts and domains.
