Traffic is up. The product is real. People are landing on the site, clicking around, even adding things to their cart.

And then — nothing.

Sales don’t match the effort. Conversion rate sits at 1.1% and won’t budge. Ad spend goes up, revenue barely moves. You keep making changes but can’t tell if any of them are working.

That’s a revenue leak. It’s not dramatic. It doesn’t look like a crisis. But it’s bleeding money quietly, every single day.

Here’s what it actually looks like — and the process I use to find it.

What a Revenue Leak Actually Is

A revenue leak isn’t one big hole. It’s usually three or four smaller ones in the wrong places at the wrong time.

The most common spots:

• Checkout abandonment — people get to the final step and leave when they see shipping costs, required account creation, or a confusing payment screen
• Product page drop-off — they read the page, stay a while, and still don’t click “Add to Cart” — usually because something is missing (proof, clarity, trust)
• Cart abandonment — items added, session ended, never recovered — often because the recovery flow is broken or nonexistent
• App conflicts — two or three tools running on your store that fight each other, slow down the page, and break the checkout flow on mobile
• Broken tracking — you’re making decisions based on bad data, so every “fix” is a guess

Any one of these can cost a $50K/month store $5,000–$15,000/month in missed revenue. Combined, they can cut your actual performance in half compared to what it should be.

The 5-Step Process I Use to Find It

When I audit a store, I work through this in order. Every time. The order matters — because fixing the wrong thing first wastes time and money.

Step 1: Check the Funnel, Not the Homepage

Most store owners focus on the homepage or the hero image when conversion problems come up. That’s the wrong place to start.

The revenue is decided in the funnel — the path from product page to checkout complete. I look at:

• Session-to-product view rate
• Product view-to-cart rate
• Cart-to-checkout initiated rate
• Checkout initiated-to-purchase rate

The step with the biggest drop-off is where the leak is. Everything else is secondary until that’s fixed.

Step 2: Walk the Checkout on Mobile

Pull out your phone — not your laptop — and go through the entire checkout as a customer. Right now.

Most founders are horrified when they do this for the first time. The mobile checkout experience is often completely different from desktop. Buttons that don’t work. Forms that are hard to fill in on a small screen. A loading spinner that sits there for four seconds before the next page loads.

Mobile is where most of your traffic is. If the checkout is broken on mobile, the funnel is broken.

Step 3: Audit Your Tracking Before Trusting Any Data

Before you trust any conversion data, verify that the tracking is actually working correctly.

This is the step most people skip — and it’s the one that causes the most damage. If purchase events aren’t firing correctly, or if they’re firing twice, or if GA4 isn’t connected to the right data stream — your numbers are wrong. And every decision you make based on wrong numbers makes the problem worse.

Check:

• Is the purchase event firing once per transaction?
• Does revenue in GA4 roughly match revenue in your store platform?
• Is the checkout funnel visible and trackable in GA4?
• Are your ad pixels receiving conversion signals?

If the answer to any of these is “I don’t know” — that’s the starting point, not the homepage design.

Step 4: Look at the Product Pages Like a Stranger

Open your best-selling product page. Read it like you know nothing about the product, the brand, or why anyone would buy it.

Ask yourself:

• Is it immediately obvious what this is and why I’d want it?
• Are there real reviews — not just a star rating, but written reviews with specifics?
• Is there a clear, low-friction way to add to cart on mobile?
• Is there anything here that makes me hesitate — shipping time, return policy, confusing variants?

Friction on the product page is invisible when you’re too close to the product. Get distance. Or ask someone who has never seen your store to try to buy something and watch them do it.

Step 5: Check the Recovery Flows

What happens when someone abandons their cart? Do they get an email? How many? How fast? Is there a discount trigger at the right moment?

Cart and checkout abandonment flows are the highest-ROI automations in e-commerce — and they’re broken or missing in a significant number of stores I audit. Sometimes the flow is set up but the trigger is wrong. Sometimes the email goes to a spam folder because the domain isn’t authenticated properly.

These flows don’t fix the underlying conversion problem, but they recover revenue that’s already been lost. They should be running correctly regardless of anything else you’re working on.

What This Looks Like in Real Numbers

Here’s a scenario I see regularly:

A brand has solid traffic — around 20,000 sessions/month. Conversion rate is sitting at 1.1%.

After a proper audit, we find two things: the checkout is loading slowly on mobile (costing 15–20% of mobile conversions), and the cart abandonment flow has a broken trigger (not sending to most abandoners).

Fix the mobile checkout load time. Fix the abandonment flow. Conservative estimate: conversion rate moves from 1.1% to 1.4–1.6%. On 20,000 sessions, that’s 60–100 additional transactions per month — from two fixes. Not from more ad spend.

That’s what a revenue leak looks like when you find it.

The Most Common Mistake I See

Founders try to fix conversion by changing what people see — new hero image, new homepage layout, new color scheme.

The design is rarely the problem. The problem is almost always in the flow, the data, or the friction points that happen after someone has already decided they’re interested.

Changing the homepage when the problem is in the checkout is like repainting the front of a restaurant when the kitchen is the problem. It might look better from the outside. But it doesn’t fix what’s actually keeping people from coming back.

How to Find Your Leak Without Guessing

The fastest path to clarity is a proper diagnostic. Not a Google Analytics rabbit hole. Not another freelancer’s “best practices.” A structured audit that looks at your specific store, your specific funnel, and your specific data.

That’s what the E-Commerce Audit is. In 72 hours, you get a clear report: what’s broken, where the revenue is leaking, and what to fix first. If you want to go further, there’s a sprint model to fix each specific problem in 14 days.
