I tend to be a little bit contrarian about the whole CPA vs. rev-share issue. As long as you and the program you’re signing up with agree on the details, then there’s absolutely nothing wrong with a CPA deal.
UNLESS someone decides to not honor their end of the deal by sending fraudulent players or by refusing to pay CPA’s that are owed.
You might argue that those issues don’t come up with rev share deals, but the fact is, there has to be a certain amount of trust involved with any affiliate partner because THEY are the ones providing you with the stats on your revenue.
If you’re dealing with someone dishonest, they’ll find a way to cheat you no matter what business plan you choose.
I’ve personally never had a problem with any of the CPA deals I’m involved with.
