I've audited over 100 funnels for $1M–$150M founders. Every single one had the same pattern: the owner thought they had a traffic problem. They were wrong.

They didn't need more leads. They needed to stop losing the ones they already had.

In this piece I'll walk you through the four categories of leaks I find in every funnel audit — what each one looks like, how to quantify it in dollars, and why the total is almost always bigger than founders expect.

The counterintuitive truth about funnel revenue

When a funnel underperforms, founders reach for the same three levers: more ad spend, a new agency, a redesigned landing page. These moves feel productive. They're also almost always wrong.

The problem isn't that you don't have enough people coming in. The problem is that you don't know where they're leaving. Until you can name the step where each dollar disappears — and quantify what that step is worth — every "fix" is a guess.

The most expensive lead in your funnel isn't the one that doesn't buy. It's the one you paid to acquire, paid to register, and then never saw again.

A good funnel audit starts with one question: where does the money physically go between the ad impression and the sale? Answer that, and the fix list writes itself.

The four universal leak categories

Every funnel — regardless of type — leaks across the same four categories. I call them the four leaks, and I measure all of them in every audit.

1. CPL Waste

Your cost per lead (CPL) is what you pay to get one person onto your list. In healthy webinar funnels, that number hovers around $15. In evergreen, closer to $20. VSL runs $25. Challenge $10. Application funnels $75.

If your CPL is 50% above benchmark, you're burning money at the top of the funnel that will never compound downstream. On a $10,000/month ad budget, a $10 CPL overage on 1,000 leads per month is $120,000 of annual overspend before your funnel even starts converting.

Rule of thumb

If your CPL is more than 30% above benchmark for your funnel type, that's leak #1. Fix it before anything else — every downstream optimisation compounds on a CPL base.

2. Engagement Gap

This is the leak between "they registered" and "they saw your offer." For a webinar, that's show-up rate. For an evergreen, landing-page opt-in. For a VSL, landing-to-video conversion. For a challenge, completion rate. For an application funnel, form completion.

Show-up rate is a classic example. The benchmark for live webinars is 50%. Most funnels I audit are at 30–35%. That gap of 15–20 percentage points is the single biggest leak in most webinar funnels — because those are people you already paid to acquire and they never saw your pitch.

3. Close Rate Gap

You've gotten them in front of the offer. Now: how many buy? This is where most founders focus — and rightly so, because close rate is leverage. A 10-point improvement in close rate isn't 50% more revenue, it's often 2–3x more revenue, because your acquisition cost didn't change.

For webinars, the benchmark close rate on attendees is 15%. Most funnels sit at 10%. For applications, benchmark is 30% close on sales calls — most funnels run 15–20%.

4. Sequence Gap

This is the quiet killer. Most founders think a funnel ends at the close. It doesn't. The average buyer says no five to seven times before saying yes. If you stop touching them after one no, you're leaving most of the money on the table.

In my audits, the Sequence Gap is often the largest dollar leak — and it's the cheapest to fix because the leads are already paid for. A 7–10 email sequence attacking one objection per email typically recovers 20–40% of the buyers who said "not yet" on day one.

How to find your specific leaks

The four categories are universal. What's specific to your funnel is where the dollar weight sits. Run this diagnostic:

  1. Map every step from ad → sale. Registration, show-up, engagement, offer view, checkout, purchase, upsell, follow-up. Every single one.
  2. Pull actual numbers at each step. Not what you think — what your analytics say.
  3. Benchmark against your funnel type. What's the industry standard at each step?
  4. Multiply the gap by your volume. That's your annual dollar leak at that step.
  5. Rank by dollar impact. Fix the biggest one first.

What you'll usually find: one or two steps account for 60–80% of your total detectable leak. Those are where you concentrate.

The math that makes this real

Let's make it concrete. Take a webinar funnel running at $50K/month revenue on $10K/month ad spend. Typical numbers:

Total detectable leak: ~$320K/year on a $600K/year business. That's more than half the revenue walking out the door — and every category above has known fixes with known recovery rates.

This is why I keep saying: you don't have a traffic problem. You have a leak problem. The good news is that leaks are knowable, measurable, and fixable — if you can see them.
