A guide to getting started with a CPA network.

I recently decided to dive into the topic of CPA marketing, but I don’t quite know where to start. I found several networks, but they are so different that it’s hard to choose the right one. What criteria would you recommend taking into account to make the right choice? And is it worth starting with several networks at once or is it better to first get comfortable with one? Of course, I’m also interested in the issue of payments — are they stable for all networks? In general, if someone can share their personal experience, I’ll be grateful!
