Buy Leads: A Buyer's Guide to Pricing, Quality and Vendors

When you buy leads, you pay for a defined result (a registration, a confirmed contact or a sale) instead of clicks or impressions. Whether that pays off depends less on the price per lead than on lead type, quality, source and contract terms. This guide is for advertisers, media buyers and affiliate managers who buy leads online, with a focus on B2C leads from consumers. You will learn the lead types and pricing models, how to check lead quality, vet a vendor and read a test order. Dating serves as the running example; the principles apply to any vertical.

What is a lead? Lead types explained

A lead is a prospect who completed a defined action and left contact details. Every deal defines its own lead, so the definition belongs in the contract, not in a sales deck.

For B2C leads, these types are common:

• SOI (single opt-in): a submitted registration without confirmation. High volume, variable quality.
• DOI (double opt-in): a registration the user confirmed in a second step, usually through a link in an email.
• Lead record: contact data such as name, email address or phone number that a vendor collects on its own pages and passes to you.
• Sale or subscription: strictly speaking not a lead but an action, typically paid on a CPA basis.

Two more distinctions affect price and value. Exclusive leads go to you alone, shared leads go to several buyers, for example through co-registration. Real-time leads are delivered the moment the user signs up, while aged leads come from older databases. For how SOI and DOI differ in counting and value, see our comparison of SOI and DOI leads.

Buying leads vs buying traffic

When you buy traffic, you pay for clicks or impressions (CPC, CPM) and carry the risk that visitors don't convert. When you buy leads, you pay only for the agreed result. The risk of weak clicks sits with the vendor, who prices it into the cost per lead.

Leads reach you in one of two ways. Either the user clicks through and registers on your own form, and the vendor is paid per lead via postback. Or the vendor collects the data on its own site and delivers the record through an API or a file.

In dating SOI and DOI deals, the first setup is common because it keeps data flow and consent in your hands. To buy clicks and run the funnel yourself, see our guide on how to buy dating traffic.

Pay per lead, CPL and CPA: pricing models and price drivers

Pay per lead is the billing model: you pay a fixed price for every valid lead. CPL (cost per lead) is that price from the buyer's side, and in practice the terms are used interchangeably. CPA (cost per action) is the umbrella term for any paid action; in dating buys it often means a first purchase or subscription.

The later the paid event sits in the funnel, the more risk the vendor carries and the higher the price per event. Our guide to cost per acquisition covers that model in depth.

There is no market price for leads. Price depends mainly on:

• Lead type and depth of checks: a confirmed or phone-verified contact costs more than an unconfirmed registration.
• GEO: purchasing power, language and competition for the same users differ by country.
• Vertical: mainstream, casual and adult dating are allowed on different sources and attract different users.
• Exclusivity: an exclusive lead costs more than one shared among several buyers.
• Source and channel: search and editorial content usually bring more user intent than broad volume sources.
• Terms: volume, caps, payment terms, hold period and return rights shift risk between buyer and seller, and with it the price.

What matters is not what a lead costs but what it earns you. Derive your ceiling from the revenue a source's leads generate. The formulas for CPL and approval rate are in our guide to EPC, CR and CPL in dating.

How to check lead quality

Lead quality shows on two levels: the individual record and what users do afterwards. Check both, split by vendor and sub-ID.

On the record:

• Validation: email syntax and deliverability, disposable domains, phone number format, required fields, age 18 or older.
• Duplicates: match against your own database, against other vendors and within the same vendor's deliveries. Agree which lead counts in a duplicate, for example the first one received.
• Consent record: timestamp, source URL, IP address and the exact wording of the consent text. Without it, you cannot show that you may use the contact.
• Source transparency: every lead should map to a source and placement. Without sub-IDs you can only cut the whole vendor, not its weak sources.

In the funnel:

• SOI to DOI confirmation rate compared with other vendors
• logins, profile completion and messages in the first days
• share of paying users and refunds
• fraud signals such as sign-ups seconds after the click, clusters of IPs or devices, and mismatches between target GEO and IP location

How to vet pay per lead companies: questions, red flags, contract

Before you buy your first lead from a vendor, get these answers, ideally in writing:

1. Which channels and sites generate the leads, and will I get sub-IDs per source?
2. Does the user register with me, or do you collect the data? With what consent text?
3. Are the leads exclusive? If not, how many buyers receive each lead?
4. What checks run before delivery, such as validation, duplicate matching and bot filtering?
5. How are leads delivered: in real time via API or postback, or in batches as a file?
6. Which leads can I return, within what period, and do I get a credit or a replacement?

Red flags include fixed lead packages at a flat price with no stated origin, “fresh lists” or aged data without consent that names you as the recipient, prepayment for large volumes with no test order, and guaranteed payer or conversion rates. No vendor can guarantee how your own funnel converts.

Your contract should cover at least the definition of a valid lead, return reasons and deadline, credit or replacement for invalid leads, caps and exclusivity, payment terms after the hold period, and each side's data protection role.

GDPR and consent when you buy leads

This section is general information, not legal advice. Once leads contain personal data of users in the EU, GDPR applies: every processing activity needs a legal basis, and if you rely on consent, you must be able to prove it.

For buyers, that means:

• Registration with you: if the user signs up directly on your form, you inform them yourself and collect the consents you need. The vendor gets only the click ID and event, no contact data.
• Delivery by the vendor: passing the data on to you needs its own legal basis, in practice usually specific consent that names you as the recipient. Ask for proof with every lead.
• Promotional emails: in Germany, the UWG (Act Against Unfair Competition) generally requires prior express consent for them. A registration is not automatically consent to marketing.

Other markets have their own rules, so check every GEO you buy in. Our guide to GDPR-compliant lead generation in dating covers roles, contracts and documentation. Get legal advice for your specific setup.

Test order and scaling: a worked dating example

Start with a test volume per vendor, fixed daily caps and criteria you set before launch: maximum cost per confirmed user and per paying user. Evaluate only after the return period ends, grouped by delivery date, since confirmations and payments arrive late.

A hypothetical example: a dating brand wants to buy dating leads and tests two vendors. Vendor A delivers SOI leads at $2.00, vendor B DOI leads at $6.00. According to the brand's own data, a paying user generates $160 in net revenue over six months, and the brand will spend at most half of that on acquisition. Its ceiling is therefore $80 per paying user.

Per lead, vendor A is three times cheaper; per paying user it costs two thirds more and lands above the $80 ceiling. Without return rights the gap would be wider: had the brand paid for all 1,000 leads from A, cost would be $2,000, or $111.11 per paying user. Vendor B meets the target and is the candidate for scaling. To work out what a paying user is worth, see our customer lifetime value formula guide.

Then scale in steps: raise caps gradually and recheck the numbers after each step, because extra volume often comes from new, less proven sources. Agree that the vendor announces new sources and delivers them under their own sub-ID. Keep a second vendor in testing as a fallback if quality drops.

Common mistakes when buying leads

1. Comparing price per lead only. What counts is cost per confirmed and per paying user.
2. Buying without return rules. You end up paying for duplicates and invalid addresses.
3. Taking on lists without consent records. Aged data whose consent does not name you is both a legal and a quality risk.
4. Judging vendors only as a whole. Without sub-IDs, a decent average hides weak sources.
5. Judging too early. Confirmations, payments and returns arrive with a delay.
6. Not rechecking when you scale. More volume often means a different source mix.

FAQ

How much does a lead cost?

There is no fixed price. It depends on lead type, GEO, vertical, exclusivity, source and terms. Work backwards: what is a confirmed or paying user worth to you, and what share of that will you spend on acquisition?

What is pay per lead?

Pay per lead is a billing model in which you pay a fixed price for each valid lead instead of paying for clicks or impressions. The contract defines what counts as valid and which leads you can return.

Is it legal to buy leads?

It depends on how the leads were generated. Personal data needs a legal basis, and passing it on to you usually needs consent that names you as the recipient. Ask for proof and have your setup reviewed by a lawyer; this answer is not legal advice.

Conclusion

Buying leads pays off when three things are in place: a written definition of a valid lead with return rights, transparent sources with consent records, and decisions based on cost per paying user rather than price per lead. Test small, evaluate by delivery cohort and scale only what passes. If you want to buy dating leads on transparent terms and measure every source on paying users, talk to Leadpartner.
