The lead-focused form of traffic arbitrage: converting paid traffic into qualified leads and selling them to advertisers at a profit.
Lead arbitrage is traffic arbitrage where the monetised unit is the lead — a user record (name, phone, email) delivered to a CPA network or advertiser — rather than a click or a sale. The margin is the payout per accepted lead minus the cost of the traffic that produced it.
Because advertisers pay only for leads they accept after their own validation, the economics turn on lead quality and fraud control: a batch with a low approve rate can be unprofitable even at a high nominal payout. This is why lead-side operations centre on the lead record and its status, not on click metrics.
The workflow after lead creation — scoring, delivery over API, status reconciliation, and payout postbacks — is the half a click tracker does not cover, and is handled by a lead CRM.
