Cost per mille requires only that the publisher make the advertising available on his or her website and display it to the page visitors in order to receive a commission. Pay per click requires one additional step in the conversion process to generate revenue for the publisher: A visitor must not only be made aware of the advertisement but must also click on the advertisement to visit the advertiser's website.
LinkConnector imposes a very rigorous and lengthy screening process, so you’ll need to prove that you have a high-quality website and established audience before being accepted. Despite its somewhat schizophrenic approach, LinkConnector does have some very happy long-term affiliates. And their “naked links” allow for direct connection to the merchant website without having to be rerouted via LinkConnector, which will give your website an SEO boost.
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.
