How Do I Get My Products into CPA Networks?

Reach out to the networks and just ask them about signing up as an advertiser, most will require an initial down payment

Just keep in mind that they usually decline many ppl asking to be advertiser.
About 80%

The one thing to accelerate your online career is to build your own offer and then leverage the networks for traffic. Reach out to the networks you are interested in working with. Most have an advertiser sign up form. Others you may need to contact their business development team directly.

Now, you need to have tracking locked down and have everything optimized. You should know exactly what you can afford to pay per lead (or sale, or whatever you are after), how much of a budget you have to spend per day/week/month. If you are looking for leads, make sure to tell the network rep which traffic sources are working and which ones to avoid. if you have a set budget, tell the rep that you need to set a daily or weekly cap on the number of leads or sales. Be prepared to submit a business credit app and always, ALWAYS sign a I/O to protect you. The more information you have the better prepared you will be.

Seriously man, I have to say this again, the way to grow HUGE is by doing what you are doing. Hat's off! Now go kill it!

and also keep in mind that big upfront payment will be also required if you will be accepted.

What about using something like Clickbank, pliums, rap bank, or I think nancast also has affiliates also... much cheaper than using a CPA network and its still a good start.

You can also start your own affiliate/CPA network then list your offer on offervault, odigger, and grab affiliates in forums, facebook groups, linkedin, etc...

super affiliate group on facebook could get some high volume affiliates, but you gotta go prepared with a good converting offer and everything worked out. Which should go with out saying if you want to use affiliates for your offer.

good luck!!
