This is their explanation of the concept behind Link Referral:
Members directory traffic – By joining, you will be included in our members directory which is visited by our community of over 150,000 members, and thousands of outside visitors on a daily basis. You’ll have the opportunity to earn a ranking at the top of your category, absolutely free! Receive valuable feedback from visitors of your website, network with your peers, and give your opinion on other websites in the directory. The more you participate, the more you get in return!
Referral based traffic – You are probably familiar with the concept of network marketing, well this is a free version of that marketing method – by registering and promoting your linkreferral affiliate link, an exponential growth of 5 levels of referrals can be created (ex. you refer 10 people who refer 10 people each who refer 10 each….), potentially 10,000s of visitors/day all viewing your link prominently in the top spot of our ‘Featured Sites’ section on our home page for your referral ID. It works because its free, fast to register, easy to implement and no risk. People that are referred from your site will have nothing to lose and everything to gain, just like you.
Search engine traffic – By registering, you’ll benefit several ways, including,
1) having your webpage listing indexed more quickly – the major search engines continuously spider our site, and the sites listed in our directory.
2) Improved search engine rankings and SEO optimization.
3) Indirect search engine traffic via linkreferral.com. Pages such as your directory listing and your affiliate page listing feature your link and description, are picked up by all the major search engines. Your sign-up description, combined with our strong traffic base (a prime ranking factor for most major search engines) can pull in a significant immediate steady stream of traffic to your listing on linkreferral.com and then on to your web site.
Linkreferral forums traffic – By participating in our forums on a daily basis, you’ll build relationships and your reputation within the linkreferral community and improve the odds of successfully converting visitors to your end goal. Promote your listing by asking questions and giving comments, each post you make actively displays your link, category and member profile.
Now, I’ve got this promoting Yuwie currently, but so far, no sign ups. It could be I’ve picked the wrong category to list the site in.
