sup BHW, I've been experimenting w/ different kinds of CPA tactics and I've found a few that are $$$. I use adwords for all my marketing efforts with a typical 200-400% roi. An ez one is make a landing page for whatever download and ask somebody to fill out an offer and you'll send a link to the download via email. You can use whatever promotion for example dating offers where you ask them to send you their "log in name". You have to spread this across multiple networks/offers becuz these will not convert long term for adveriser. To stay organized just set up different emails accnts. I use mightyb's method/landing page for this and I also use cakeslice (w/ email submits only) which I know there's been problems w/ but so far I've been fine and doing a low volume spreading out over multiple networks. You can use "alternative links" to capitalize on other offers which I do as well. This also works well because there is typically not too many bidders for "download whatever" so cost is low. use this site Code: http://tools.seobook.com/keyword-tools/seobook/ and search the words "free" and "download". Or you can target specific movies/tv shows/video games/porn star names - build landing pages around and keep your bids low. Obviously we can easily find downloads to anything we want via torrents but most people don't know about these. And when you email them back you can have them opt in to your list in order to gain access to whatever they want to download.
