Free course · For online store owners
Find the leak costing you the most sales, put a dollar value on it, and know exactly what to fix first.
Somewhere between a first visit and a paid order, one step in your store loses far more buyers than the rest. This free course shows you how to measure your conversion, map where visitors leave on phone and desktop, and work out what each leak is worth, so your next fix is the one that matters most.
- Know your numbersThe five numbers that measure conversion, each one simple sum, recorded as a baseline.
- See where buyers leaveYour funnel step by step, on phone and desktop, with the reason buyers leave at each step.
- Fix the right thing firstA dollar value on every leak, sorted, so the one worth fixing first is at the top.
Watch: what the course covers, in just over two minutes.
Who this is for
Store owners who get visitors and want more of them to buy.
Most stores lose buyers at one step more than any other: the product page, the cart, the checkout, or only on phones. Without the numbers, the fix is a guess, and the money goes on more ads, a new homepage or another discount while the real leak keeps costing orders.
- 01Stores with traffic and not enough orders
Visitors arrive and leave. You find the exact step where most of them go, and why.
- 02Owners who have never read their analytics
Shopify and Google Analytics hold the numbers. You learn which five counts matter and where to find each one.
- 03Stores paying for ads
Every extra visitor leaks at the same rate. You find the leak before buying more traffic into it.
- 04Owners starting with AI
Claude works out every rate and value from your own export, writes every sum out, and stops if the numbers do not add up.
- 05Freelancers and agencies
Auditing client stores. One repeatable map that shows a client where the money is lost and what to fix first.
For store owners from beginner to expert. No experience needed, on any e-commerce platform: Shopify, WooCommerce or anything else with Google Analytics.
Three lessons: measure it, map it, value it
Each lesson builds on the file the one before it made.
Lesson 1 records your numbers. Lesson 2 maps where visitors leave. Lesson 3 puts a value on each leak, so the first fix is clear.
Lesson 1 · Measure it
The 5 numbers that measure conversion
- Conversion rate, order value, revenue per visit, cart rate, checkout completion
- Where to find each count in Shopify and GA4
- A dated baseline, every sum written out
- You build
cro-baseline.md
Lesson 2 · Map it
Where visitors leave your store
- Your funnel, step by step, with a rate for each step
- Phone and desktop side by side
- The 5 reasons buyers leave, with evidence
- You build
leak-map.md
Lesson 3 · Value it
A dollar value on each leak
- Extra orders if one step reached a target you choose
- A worked table for every step, phone and desktop
- Sorted, so the first leak to fix is at the top
- You add the value column to
leak-map.md
Then the live workshop: six prompts, run in one Claude conversation on your own analytics export, so you leave with both files built.
What you walk away with
A map of where your store loses buyers, and what each leak is worth.
Every number has its sum written out beside it, so you can check it, and so can anyone you hand it to.
- cro-baseline.md: your five numbers from one date range
- leak-map.md: every step, its rate, reason, evidence and value
- Your conversion rate, order value and revenue per visit
- The step that loses the most visitors, on phone and on desktop
- The landing pages that start visits which rarely order
- The reason buyers leave at each step: Fit, Clarity, Trust, Cost or Effort
- A dollar value for every leak, at a target rate you choose
- The one leak to fix first, and a baseline to check it worked
Plus a plain-English glossary in every lesson: session, conversion rate, AOV, revenue per visit, funnel, step rate, drop-off, target rate and more.
Why fixes miss
The money goes on the fix that is easiest to guess, not the one that matters.
Each of these looks like progress. Each one leaves the biggest leak where it is.
- ×More traffic into a leaking funnel
Paying for visitors before fixing the step that loses them. Every extra visit leaks at the same rate.
- ×One conversion rate for the whole store
An all-devices figure that hides the step where phones leak and desktops do not.
- ×Fixing what someone noticed, not what the numbers show
A new homepage when the leak is at checkout, or a redesign when the delivery charge is the reason buyers leave.
- ×No baseline to compare against
A change goes live and nobody can say whether it helped, because nobody wrote the numbers down first.
None of this needs new tools. The numbers are already in your analytics.
The five reasons buyers leave
Every leak on the map gets one reason, and the evidence for it.
The reason decides the fix. The evidence comes from your own support questions, reviews, policies and analytics.
- 1Fit
The wrong product for the visitor, or the wrong visitor for the product.
- 2Clarity
The buyer cannot tell what it is, what it does or what it really costs.
- 3Trust
The buyer is not sure the store, the product or the payment is safe.
- 4Cost
The price, the delivery charge or a surprise cost at checkout.
- 5Effort
Too slow, too many steps, or hard to use on a phone.
The through-line
Every number has its sum beside it.
Claude does the arithmetic from your own export, writes every sum out, and stops if the counts do not add up. The value on each leak is an estimate at a target you choose, never a forecast.
- 1Your counts, from one date range
Sessions, product views, carts, checkouts, orders and revenue, from Shopify or Google Analytics, by device if you have it.
- 2Claude maps and values them
Step rates, the device split, the reason at each step and the value of each leak, with every sum written out.
- 3You check and choose
A final prompt re-checks every sum in both files, and you pick the first leak to fix from the top of the list.
How the course runs
Three lessons of 12 to 17 minutes, then a live workshop.
Each lesson is fifteen slides built around diagrams and worked examples, with every term explained the first time it appears. Watch them in order: each lesson reads the file the one before it made.
Lesson 1
The 5 Numbers That Measure Conversion
The five counts, the five numbers and their sums, where to find each count in Shopify and GA4, how revenue is built, and how to record a baseline.
Lesson 2
How to Map Where Visitors Leave Your Store
The funnel and its step rates, phone against desktop, landing pages, finding the biggest drop, and the five reasons visitors leave.
Lesson 3
How to Put an Estimated Value on Each Leak
The value method, choosing a target rate, the worked table for every step, what the number is and is not, and choosing the first leak.
Workshop
Live build: your baseline and leak map
Six prompts from the SOP & AI Prompts pack, run in one Claude conversation on your own analytics export.
Where to go next

Quick answers
The questions people ask before starting.
Is it really free?
Yes. Three lessons, the live workshop and the SOP & AI Prompts pack, with lifetime access and no payment.
Do I need any experience?
No. Every lesson explains its terms in plain English the first time they appear, and every sum is worked through step by step.
What do I need to have ready?
An analytics export for one date range: sessions, product views, add-to-carts, checkouts, orders and revenue, split by device if you can. Your support questions, reviews and delivery policy help with the reasons.
Which platform does it work with?
Any store with Shopify Analytics or Google Analytics 4. The lessons show where each count sits in both.
Which AI does it use?
Claude. The six workshop prompts run in one Claude conversation, work only from the numbers you paste in, and write every sum out.
Is the dollar value a forecast?
No. It is the extra orders one step would have brought at a target rate you choose, times your order value. It ranks the leaks so you know where to look first.
What if my store is small?
It still works. When counts are small, the course shows you how to read the counts themselves rather than lean on percentages.
What exactly do I get?
Three video lessons with fifteen-slide diagram decks, the live workshop, and a PDF SOP with all six prompts. You finish with two files: your baseline and your leak map.
Find the leak costing you the most sales.
Measure your conversion, map where visitors leave, and put a value on every leak — in three short lessons and one workshop, free.

The Conversion Leak Audit
-
1
Lesson 1 — The 5 Numbers That Measure ConversionHow to measure how well your store turns visitors into orders, from five counts and your revenue. The five counts are sessions, product views, carts, checkouts and orders. From them come the five numbers: conversion rate, average order value, revenue per visit, add-to-cart rate and checkout completion rate, each worked out as one sum. You learn where to find each count in Shopify Analytics and in a GA4 funnel exploration, and how revenue is built from sessions × conversion rate × average order value. You then record a baseline from one date range, with every sum written out, so every later change can be compared against it. The result is cro-baseline.md. Terms explained include session, conversion rate (CVR), average order value (AOV), revenue per visit and baseline.

Lesson 2 — How to Map Where Visitors Leave Your Store
How to find the exact step where your store loses the most buyers. The lesson lays out the funnel as five counts and four steps, each with its own step rate and the number of visitors who left. You draw the same funnel twice, for phone and desktop, because the two often leak at different steps, and you check which landing pages start sessions that rarely order. Each leak is then matched to one of five reasons visitors leave: Fit, Clarity, Trust, Cost or Effort, with the evidence for it from your support questions, reviews, policies or analytics. The result is leak-map.md, with every step's counts, rate, reason and evidence. Terms explained include funnel, step rate, drop-off, leak, device split and landing page.

3
Lesson 3 — How to Put an Estimated Value on Each Leak
How to work out which leak is worth fixing first. For each step, you raise its rate to a target you write down, such as 10% higher or your desktop rate, hold every other step the same, and multiply the extra orders by your average order value. You learn how to choose a target rate, work through a full table for every step on phone and desktop with every sum written out, and see why the values are never added together. The result is an estimated value at the target rate, not a forecast: it ranks the steps so you know where to look first. You then sort the leaks by value, check each has evidence and enough visits, and choose the first leak to fix. The value column is added to leak-map.md. Terms explained include target rate, relative rise, percentage point, benchmark and estimated value.

Live Workshop — The Conversion Leak Audit
The six prompts from the SOP & AI Prompts pack, run in order in one Claude conversation on your own analytics export. They build the baseline, map the funnel and step rates by device, collect the evidence and assign a reason to each leak, calculate the estimated value per step, sort the leaks and choose the first one to fix, and check every sum in both files. You leave with cro-baseline.md and leak-map.md, and the one leak to fix first.
The SOP shows its example figures in £ and its prompts round money to the penny. Your own will be in your currency.
