I started AM a while ago and am just getting back into it. After reading/listening to super affiliates advice I want to stick to one vertical and master it. I have ran two profitable PoF campaigns before without much optimization and direct linking. I have also ran one profitable diet campaign on fb. What vertical would you suggest an affiliate start with slightly more knowledge than a beginner?
Depends on the traffic source.
With that said I would pick dating over diet. Generally offers have lower payouts so you need a smaller budget to start testing.
