VigLink works a bit differently than other affiliate programs in that it is specifically designed for bloggers. Instead of affiliates picking and choosing which merchants to work with, VigLink uses dynamic links that automatically change to work with merchants that VigLink has determined are offering the highest conversation rates and/or commissions at any given moment.
VigLink is an intermediary platform, so it can serve as a backdoor for affiliates who have previously been banned/suspended from working with other affiliate programs like Amazon. And while you can choose specific merchants or offers, VigLink can be set up to work automatically by scanning your published content and dynamically generating affiliate links, making it a great choice for established content producers who are looking for a simpler way to generate revenue via an affiliate program.
The phrase, "Affiliates are an extended sales force for your business", which is often used to explain affiliate marketing, is not completely accurate. The primary difference between the two is that affiliate marketers provide little if any influence on a possible prospect in the conversion process once that prospect is directed to the advertiser's website. The sales team of the advertiser, however, does have the control and influence up to the point where the prospect either a) signs the contract, or b) completes the purchase.
Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives a commission. The advertiser must convert that visitor first. It is in the best interest of the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss are shared between the affiliate and the advertiser.
In November 1994, CDNow launched its BuyWeb program. CDNow had the idea that music-oriented websites could review or list albums on their pages that their visitors might be interested in purchasing. These websites could also offer a link that would take visitors directly to CDNow to purchase the albums. The idea for remote purchasing originally arose from conversations with music label Geffen Records in the fall of 1994. The management at Geffen wanted to sell its artists' CD's directly from its website but did not want to implement this capability itself. Geffen asked CDNow if it could design a program where CDNow would handle the order fulfillment. Geffen realized that CDNow could link directly from the artist on its website to Geffen's website, bypassing the CDNow home page and going directly to an artist's music page.
