The leak is usually at the checkout

Most people look at their store's results as one number. Sales are up, sales are down, the ads are working, the ads are broken. That single number hides everything you actually need to know.

A funnel is a walk. Somebody sees the ad. Some of those people click. Some of the clickers land and look around. Some add a product to the cart. Some initiate checkout. Some finish. Every step is a door, and at every door you lose a percentage of the crowd. That part is normal — it's what funnels do.

The question that pays is: which door is losing more than it should?

The tell I found in my own numbers

When I ran this exercise on one of my own e-commerce funnels, the read was clear. People were initiating checkout — and then not completing the purchase. They walked all the way to the register, wallet out, and left.

Think about what that means. The ad worked. The landing page worked. The product page convinced them. The intent was there. The failure was in the last room of the house — the checkout itself.

So I spent a couple of days fixing that one room. Branding elements, so the page still felt like the store they trusted a second ago. Trust factors, so the doubt that shows up right before a purchase had an answer in front of it. Nothing glamorous — the digital equivalent of cleaning up the register area. And meaningfully more of the people who started checkout began finishing it.

How to run the same audit

1. Lay out your funnel as named steps: impression, click, product view, add to cart, initiate checkout, purchase.
2. Get the count for each step over the same period, from the data itself — not from memory, not from feel.
3. Turn each pair of steps into a ratio, and ask which handoff looks weakest relative to the others.
4. Fix only that step. Resist redesigning everything — the strong steps are already paying your bills.
5. Re-read the same ratios afterward, and let the numbers tell you whether the fix worked.

This is also a place where connected AI changes the tempo. With the store and ad platforms wired into one interface, I ask for the funnel read in plain language and get every step-to-step ratio in seconds, with the weak handoff flagged. The thinking is still mine. The counting no longer costs me an afternoon.

Before you touch your ads, read the walk. The most expensive leak in e-commerce is the one at the very end — because everybody standing there already said yes.
