In the case of cost per mille/click, the publisher is not concerned about whether a visitor is a member of the audience that the advertiser tries to attract and is able to convert, because at this point the publisher has already earned his commission. This leaves the greater, and, in case of cost per mille, the full risk and loss (if the visitor cannot be converted) to the advertiser.
Always be on the lookout for eye-catching affiliate ads as you browse the web. Keep a document or Pinterest board of great ads that you can reference. This helps you in many ways — you’ll stay current on design trends, you’ll see what competitors are creating and you’ll be inspired. Plus, when the time comes to create an amazing ad, you’ll be ready.
Win-win-win. The advertiser wins because they only pay when a purchase is made (as opposed to the shotgun approach of paying to advertise to the masses and waiting for a small percentage to actually buy). The affiliate wins because they make money while providing helpful advice. The customer wins because they get a trusted recommendation for something they might not otherwise have known about.
