The trick is finding a good affilate program or diversifying programs if it is allowed. I'm thinking of setting up an affiliate account with hosting providers with software I am working on. I have found that there are a lot of affiliate programs from a lot of different hosting providers. Problem with apps is there aren't very many stores. I make some money from Apple as an app developer but I don't expect that income to last for ever or even from month to month. It could vanish at any time and I got no recourse for it.
