In effect, VigLink works as the middleman between a publisher (blogger) and merchants by scanning the publisher’s content and automatically creating links to publishers that are chosen “in real time” based on their payout/conversation rates. This makes VigLink a very hands-off affiliate program for publishers who prefer to focus on content instead of managing their affiliate links.
I concluded that having read a product review, people felt more informed to make a purchasing decision. As a result, if they did click a link after reading the review they were more likely to buy the product. Those clicking on the top link seemed to be more in a ‘surfing’ mode. They clicked on the link less because they wanted to buy it but more out of interest to learn more. Some bought the product and some bought other products once they were ‘in the door’ at Amazon.
