The same few leaks, in almost every store.

Getting people to your shop is the expensive part. Losing them once they're there is the avoidable part. Most stores leak sales in the same handful of places, here's where, and the plain changes that plug them.

Orange = where most stores lose the sale. Each step is a chance to win it back.

Say 100 people visit your shop and 2 buy. That's a 2% conversion rate, completely normal. Now nudge it to 3%. You haven't spent a penny more on ads, but you've made 50% more sales from the exact same traffic. That's why this is the highest-leverage work in an online business.

You don't fix it with a redesign. You fix it by plugging the specific leaks, one at a time, and measuring as you go.

One number to watch

Conversion rate is simply buyers ÷ visitors. Your shop platform already tracks it. The goal isn't a magic figure, it's this month higher than last month. Pick it as your single headline number and most decisions get easier.

A 1-point lift in conversion is usually cheaper to win than the same growth bought through advertising, and it compounds on every campaign after.

The product page

This is where the "yes" happens or doesn't. The reliable wins:

The checkout

The checkout is where the most sales leak away, often more than half of full baskets. The fixes are almost always about removing friction, not adding features:

Trust & speed

Two quieter factors sit under everything. Trust: a padlock in the address bar, visible returns and contact details, and real reviews all tell a nervous first-time buyer it's safe to enter their card. Speed: a slow shop bleeds customers before they see anything — every extra second of load time measurably drops sales, and phones on patchy connections feel it most.

None of this is guesswork. You change one thing, watch the number for a couple of weeks, keep what works. If you'd like a fresh pair of eyes on where your store is leaking, and a short, prioritised list of fixes, that's exactly the kind of work I do. Get in touch and we'll start with your biggest leak.
