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.
A more complex system, pay per lead affiliate programs compensates the affiliate based on the conversion of leads. The affiliate must persuade the consumer to visit the merchant’s website and complete the desired action — whether it’s filling out a contact form, signing up for a trial of a product, subscribing to a newsletter, or downloading software or files.
Use variety. Mix and match affiliate ads so you don't overwhelm your visitors (content-embedded affiliate links usually have the best click-through rates over image links.) Consider using a lead page and funnel system to market your affiliate business. Lure prospects to your email list with a free offer and include links to your affiliate product pages.
