The other reply is kinda harsh but not wrong - pop arb has a steep learning curve.
Basic idea: buy cheap pop/popunder traffic, send it to an offer that pays more than you spent. Sounds simple but margins are razor thin.
What you need to start:
- Tracker (Bemob free tier works)
- Traffic source (PropellerAds, RichAds, etc)
- Offers that accept pop traffic (smartlinks or specific offers from your AM)
- At least $200-500 to burn while learning
Start with smartlinks to test geos. Track everything. Most campaigns lose money - you're looking for the 10% that profit.
It's not a "teach me everything" situation though. You gotta test, lose some money, learn from the data. Nobody can shortcut that part for you.
