Key takeaways
- A lead is only worth paying for once it is confirmed and fits your audience, so price the qualified step, not the raw form fill.
- Your maximum cost per lead comes from customer value times close rate, divided by your target return, and it rises at every deeper stage.
- Ask for as little data as you need, keep marketing consent separate and unticked, and make it as easy to withdraw as to give.
To get qualified leads, offer something your ideal customer actually wants, ask for as little as possible in exchange, confirm the contact details before you count the lead, and score each lead on fit and intent. Then pay only up to what a qualified lead is worth to you, which you work out from your close rate and the value of a customer.
Lead vs qualified lead
A lead is anyone who leaves contact details or signs up: a form submission, a waitlist entry, a free account. A qualified lead is a lead that has passed checks you defined in advance, typically three:
- Real: the contact details work, for example the email address was confirmed.
- Fit: the person matches your audience, such as the right country, role, company size, or need.
- Intent: they did something that shows interest beyond the form, such as opening the product, booking a call, or finishing setup.
Write your definition down before you run a campaign, or you will compare channels on numbers that mean different things. What is CPL? covers the usual lead levels and the basic cost per lead formula.
Lead magnets that attract the right people
A lead magnet is what people get in return for their details. The best ones are useful only to the people you want, which filters the audience for you.
- Templates and checklists tied to a task your customer does every week.
- Calculators and small tools that answer a real question with the user’s own numbers.
- Free trials or free plans, where the product itself does the convincing.
- Waitlists for a launch, when early access is genuinely limited.
Avoid generic prizes such as gift cards as the hook. Everyone wants one, so they bring volume and very little fit.
Form design: ask less, learn more later
Every field costs some sign-ups, but a field that tells you who is qualified can be worth it. Ask only for what you need to deliver the lead magnet and to qualify the lead, and collect the rest later.
- Start with email only, or email plus one qualifying question, such as team size or country.
- Put the value right above the button: what they get and when.
- Add a bot check, and block disposable email domains if junk becomes a problem.
- Ask one or two more questions on the thank-you page or in the first email, once the person has committed.
The page around the form matters as much as the form. Run through the landing page checklist before you pay for traffic.
Verify before you count
Send a confirmation email with a link, and count the lead only after the link is clicked. This is often called double opt-in. It removes typos, fake addresses, and most bot sign-ups, protects your sender reputation, and gives you a timestamped record of who asked to hear from you.
For higher-value leads, add a second check such as a phone number verified by code or a completed first step in the product.
Lead scoring basics
Lead scoring gives every lead points, so you spend time on the ones most likely to buy. Start simple and score two things:
- Fit points for matching your audience, for example +10 for a target country and +15 for the right company size.
- Intent points for actions, for example +10 for a confirmed email, +20 for finishing onboarding, and +30 for booking a demo.
Pick a threshold, say 40 points, above which a lead counts as qualified. After a few months, check which points actually predicted customers and adjust.
Work out your maximum cost per lead
The most you can pay for a lead depends on how deep that lead is. Use the same formula at every stage:
- Value of one lead = close rate at that stage × value of one customer.
- Maximum cost per lead = value of one lead ÷ target return on ad spend (ROAS).
Use gross profit over a period you trust as the customer value, not revenue. CAC vs CPA vs LTV explains how to estimate it.
Example: an invoicing app prices three lead stages
The numbers below are an example. A small invoicing app earns $300 in gross profit from a customer in the first year and wants a target ROAS of 2, so every $1 of ads should return $2.
| Stage | Share that becomes a customer | Value of one lead | Maximum cost per lead |
|---|---|---|---|
| Raw sign-up | 2% | $6 | $3 |
| Confirmed email | 5% | $15 | $7.50 |
| Qualified: created a first invoice | 12% | $36 | $18 |
The same person is worth six times more once they have confirmed and used the product, so one flat price for every form fill either overpays for junk or underpays for the leads that matter. The cost per result calculator runs this math with your own figures.
Privacy and consent basics
A lead is personal data, and the rules depend on where your leads live. This is general guidance, not legal advice, so check the rules in the countries you target. A few habits help almost everywhere:
- Say what happens next. Tell people who you are, what they will receive, and how often.
- Collect only what you need for the purpose you stated.
- Keep marketing consent separate and unticked. In the EU, the GDPR says in recital 32 that silence, pre-ticked boxes, or inactivity do not count as consent, and Article 7(2) requires a written consent request mixed with other matters to be clearly distinguishable from them.
- Make leaving easy. Under GDPR Article 7(3), withdrawing consent must be as easy as giving it. An unsubscribe link in every email is the minimum.
- Keep records of when and how each person signed up, and never share or sell leads to others unless people clearly agreed to it.
Paying per verified lead on Sharklio
Sharklio is a pay-per-result platform, so you pay for sign-ups that happened, not for clicks. There are two ways to do it.
Task campaign: verified sign-up with proof. Ask users to create a free account, confirm their email, and submit a screenshot of the confirmation screen plus the email they used. You check each one against your database and approve or reject it in your dashboard. Pick an approval window (30 minutes to 3 days) long enough to check, because unreviewed completions are approved automatically. Rejections need a reason, and users can dispute one once within 72 hours. The minimum price is $0.01 per completion.
Offer campaign: pay more for the deeper step. If your server can send a postback, build a multi-step offer. In the example above, the app could pay $0.50 for the sign-up, $1.50 more for the confirmed email, and $4 more for the first invoice. A user who reaches every step costs $6, well under the $18 that a qualified lead is worth. Each step can have its own price per country, and a conversion can be reversed for up to 30 days if it turns out to be invalid.
Rewarded sign-ups are not organic sign-ups
Offerwall users sign up for a reward, so their close rate will usually differ from your organic leads. Measure it rather than assuming the table applies, and put most of the price on the step that proves real use. Do not use rewarded sign-ups to fill a sales calendar with demo calls, or to generate leads you resell to someone else.
Test a confirmed-lead campaign
Start small in one or two countries, compare the real cost per qualified lead with your maximum, and scale only what clears it. Create a free account to build your first campaign.
Frequently asked questions
What is the difference between a lead and a qualified lead?
A lead is anyone who leaves contact details. A qualified lead has also passed your checks: working contact details, a fit with your audience, and an action that shows real interest.
Is double opt-in required?
Not everywhere, but it is good practice. It removes fake and mistyped addresses and gives you a record of who asked to hear from you.
How much should I pay per lead?
Multiply your close rate at that lead stage by the value of a customer, then divide by your target ROAS. A confirmed or qualified lead is worth more than a raw sign-up, so it can carry a higher price.
Can I buy leads on Sharklio?
Sharklio does not sell contact lists. You can pay per verified sign-up with a task campaign where you review the proof, or per confirmed step with a multi-step offer that your server reports by postback.
