Calculator 1

Kept before ads

Chapters 2 and 19. Compare your ad cost per order with what an order keeps before ads. Never with profit, or you count the ads twice.

Calculator 2

Leak Score

Chapter 24. Tick the urgent override for anything that takes money wrongly, blocks buying, creates a legal or safety risk, or breaks your numbers. Fix those today. Score the rest.

Checklist

The 30-Day Fix Plan

One rule runs through the whole month: if you find something that meets the urgent override, fix it that day. Do not wait for Week 2.

Week 1. Find

Day 1: Work out your Leak Equation (Worksheet 1).
Day 2: Walk the Buying Path on your best seller (Worksheet 3).
Day 3: Click every live ad, email and partner link through to checkout.
Day 4: Start your Promise Register with shipping, returns, delivery and your main offer.
Day 5: Pull out anything that meets the urgent override. Score the rest. Sort into Stop, Fix, Feed.

Week 2. Stop

Fix every Stop item: broken buttons, discounts that fail, default sizes, checkout surprises.
Test each fix twice, on a phone, as a stranger.

Week 3. Fix

Make every promise match across the store, using the Promise Register.
Put sizing, delivery, returns and proof beside the button on your top five products.
Rewrite every saving in money.
Clean up your product feed and store search.

Week 4. Feed and repeat

Set up the first post-purchase messages (Chapter 22).
Shift ad spend, in steps, towards the channel with the best profit per order after ads.
Run your first 30-minute Weekly Leak Review.
Walk the path again. Score anything new.
