Same here, this post kind of fell from the sky at such a great time. Been building a great community of readers over the years but reached a point where I’m losing money maintaining the site and newsletter. As you said, the ads don’t bring much -ironically I use Adblocks too but affiliate marketing always seemed like a weird and opaque subject. I’ve read many of Chris Guillebeau’s books in the last few months (this is how I discovered your site actually!) and I didn’t realize he had affiliate links for instance. Your post opened up a new window of possibility for me. Still need to process everything and do the work behind but a big thank you to you Sean!
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.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
