Hi,
I started creating affiliate networks lists for each vertical I want to promote.
While doing so, I got to understand that some of the networks only accept publishers (= us affiliate marketers) who use websites, apps, and other digital assets to promote offers.
So- if I want to drive traffic from traffic sources (google, FB, etc.) to a pre-lander that leads to an offer LP (or directly to the offer LP)- do I need to specifically apply to CPA networks or subs-affiliate networks?
Assuming I am right-
1) how can I identify which network accepts such non-digital asset-based traffic?
2) What are the biggest CPA networks out there?
3) I'm looking for recommendations for the best CPA networks for these verticals: insurance, investment, banking, real estate, Automotive, dating, travel, experts, Education, shipping, Loans
@vortex- I'm sure you have the right answer as usual 
thanks a lot!
