Here's the explanation and claim from their website (http://www.clickinc.com/trulink.html): In any of our competitors' programs, affiliates will link to you using a unique ID (affiliate will link using http://www.merchant.com/product?affid=XXXX). Google ranks pages using an algorithm that checks how many links are pointing to a web page. Web pages that have more links will always rank higher (Google reckons page must be important since many people link to it). The problem is that http://www.merchant.com/product (page that you want to achieve high rankings) and http://www.merchant.com/product?affid=XXXX are actually different pages from a Search Engine point of view and as such, even if you have many affiliates, they all seem to link to a different page (since XXXX is a unique number), so affiliate links won’t establish http://www.merchant.com/product as a page with many links to it. This is where ClickInc.com changes everything Every time a web page gets a visitor, the referral URL (previous website) is included in the HTTP request. What we did is to have affiliates register their URL with our affiliate software and for every visitor we check if the referral URL matches an affiliate. Think about the referral URL as being used as a unique ID. Since we have a unique ID in the referral URL, affiliates can send traffic by linking directly to http://www.merchant.com/product; hence we called it TruLink. Hopefully some of the affiliate experts here can either vouche for this or rip it apart. Have at it please. Is this BS or accurate? does trulink provide a real SEO advantage? if it is accurate, why isn't everyone offering this? If not already clear, I have no connection with these guys. Just doing some due diligence on several affiliate platforms. Thanks
