I think mobile affiliate marketing is very interesting if mobile websites and payment gateways can make affiliate purchasing (or purchasing in general) to have a seamless, friction-less experience for mobile.
Everything's compressed and simple in mobile browsing - so if mobile purchasing could be as compressed and simple, I think affiliate marketing could see a huge boost in sales volume.
YOU are the business!
For most affiliate marketers, it's a one-man operation.
This means you are going to be responsible for your own success and failure.
Don't let one winning campaign get to your head.
Instead, think about how you can grow and scale into something much bigger -- this includes building out your own sites, ad campaigns, mailing lists and actually owning the data and products you are selling.
Affiliate marketing is here to stay... Anyone can make money with a fly-by-night ad campaign or website, but if you want to make long-term money, you need to think like a real business.
