Pay per lead
also pay-per-lead
The commercial model this whole industry runs on: the buyer pays for each qualified lead delivered, rather than paying for ad spend, clicks, or a monthly retainer. The price is either agreed per lead or set by buyers bidding above the seller's minimum. The seller carries the risk of generating the lead; the buyer carries the risk of converting it.
Almost everything else on this page exists because of that arrangement. Once money changes hands per lead, what counts as qualified, who the lead goes to, whether it was exclusive, and whether it can be returned all stop being details and become contract terms worth arguing over.
A pay-per-lead agency sells leads instead of charging clients a monthly fee, often with buyers funding a wallet that each lead is charged against. See the pay-per-lead agency model.
Pay per call
The same model priced per qualified inbound phone call rather than per form submission. A call counts once it stays connected past an agreed duration, which filters out wrong numbers and immediate hang-ups.
Calls are harder to run: a buyer has to answer live, and a call nobody answers cannot be sold later. Juiced distributes web leads; calls need separate call tracking. See pay-per-lead vs pay-per-call.
Cost per acquisition
CPA, pay per acquisition
Paying only when the lead becomes a defined outcome: a sale, or in legal work a signed retainer. This pushes conversion risk from the buyer onto the seller, and prices accordingly. Sellers accept it when they trust the buyer's reporting, which is the catch.
Cost per lead
CPL
What a buyer pays for one lead. The headline number in most negotiations, and on its own almost meaningless: a more expensive lead that converts more often can be the cheaper lead.
Revenue per lead
RPL, EPL, earnings per lead
What a seller actually earns per lead generated, averaged across the ones that sold at full price, the ones that fell to a lower tier, and the ones nobody bought. The number that tells a seller whether a traffic source is viable.
Margin
spread
The gap between what a reseller pays for a lead and what they sell it for. For companies that both buy and sell, this spread is the entire business model, which is why they care so much about placing each lead with the highest bidder rather than the first one.
Caps and budgets
Limits a buyer sets on how much they will take: per day, per week, per month, often broken down by state or lead type. When a cap is hit the buyer stops accepting, and your distribution has to route elsewhere rather than stall. Caps reset on schedules that vary by buyer, which is a detail worth getting right.
Contact rate
The share of purchased leads a buyer actually reaches by phone. Speed to dial, time of day, and whether the lead was exclusive all affect it. Set expectations about it on the first call, because buyers will blame the leads.
Conversion rate
close rate, sign rate
The share of leads that become the outcome the buyer is paying for, which in legal work is a signed retainer rather than a sale. A buyer who tracks it can judge a source on more than cost per lead.
Shaving
A buyer under-reporting the leads they received or accepted, so they pay for fewer than they took. It is difficult to prove from one side, and it is the main reason sellers keep their own independent record of every post and every response.
The practical defense is logging on your own system rather than trusting the buyer's dashboard, and reconciling the two regularly.
