More traffic won't fix it. Most founders scale ad spend into a funnel that's leaking, and lose more, faster.

Why This Publication Exists

Most founders diagnose the wrong problem.

When growth stalls, the instinct is to fix everything. More ads. A new landing page. A redesigned checkout. But most of those fixes address symptoms, not causes.

The money is usually leaving somewhere you're not looking. A checkout leak masquerading as a traffic problem. A trust gap masquerading as a pricing problem. Every dollar of new traffic just leaks with the rest.

This publication gives you a categorized map of the 15 most common revenue leaks across traffic, site, checkout, and retention, with the exact symptoms and the check to run for each, so you can find where your money is actually going before you spend another dollar acquiring more.

What You'll Be Able to Do

After reading this publication.

  • Spot the 15 revenue leaks by their symptoms, before they show up as a plateau
  • Run the exact check for each leak on your own store in under ten minutes
  • Rank every leak by what it costs you monthly, not by guesswork
  • Fix leaks in the right order: payback speed, not effort
  • Tell the difference between a symptom and the leak actually causing it
  • Recognize the recurring leak patterns that quietly cap brands at $50K

Inside the Publication

What the publication covers.

01

The Four-Stage Funnel

Why revenue leaks cluster in four places: traffic, site, checkout, retention, and how they compound.

02

Traffic-Stage Leaks

Four leaks where spend is wasted before a visitor ever lands: attribution blindness, broken tracking, wrong budget structure, creative fatigue.

03

Site-Stage Leaks

Four leaks between landing and add-to-cart: the 3-second homepage test, weak product pages, mobile-first failure, missing trust signals.

04

Checkout-Stage Leaks

Three leaks at the moment of purchase, where the fastest-payback fixes in the whole funnel live.

05

Retention-Stage Leaks

Four leaks after the first order, where plateaued brands lose the most and see it the least.

06

The Prioritization System

How to rank every leak you find by impact ÷ effort, and fix the right ones first.

Reading finds the leaks. A diagnostic tells you which one to fix first.

If you'd rather have the leaks in your specific business found, priced, and put in priority order, that's exactly what the diagnostic is for.
