Monthly commission affiliate program for subscription service

After some digging, I found almost all services allow for monthly commission.

Here is a few for someone searching for the same -

1. Commission Junction
2. ShareASale
3. JVZoo

Looks like you answered your own question

Yes, all of those that you mentioned are good for different things or different reasons. I would do my research before choosing one. JVZoo is better for involving Joint Venture partners with whom you have an existing business relationship. It's generally more exclusive and gives you a little bit more control over the "who and how" as far as how your product is promoted and who is doing it. It's also great if you don't necessarily want a legion of bozos spamming the web with cheap, hypey type offers but you can control that to some extent by providing a quality product. Commission Junction is great but there is a lot of competition so having an established brand and existing sales and market is very important. I don't know much about ShareASale but they seem to be pretty much like Commission Junction. A subscription service sounds more like an information product though. For that you may want to try Clickbank, or the PayPal network. They have a better reputation for those kinds of products and you can quickly gain a good number of affiliates. You will want to take some time to tweak your offer for paid traffic to make sure it converts as that is how many of your best affiliates will want to promote it. After your product gets some sales volume then the organic search affiliates will start promoting it and it could really take off. Good luck with your venture.
