What is Traffic arbitrage?
It is the core of media buying in affiliate marketing. An arbitrage affiliate buys traffic, for example popunders or push ads at a fixed CPM, and earns CPA, CPL or RevShare commissions from the conversions. Profit is commissions minus ad spend.
The work is testing: offers, GEOs, devices, landing pages and creatives. Arbitrageurs rely on tracking with postbacks to see which placements bring conversions, cut the losing ones and scale the winners.
It requires a budget you can afford to lose while testing. Before buying traffic, check that the offer allows the source, has no brand bidding or other restrictions you would break, and that its cap leaves room to scale.
