E-shop revenue is the product of four numbers:
Revenue = Visitors × Conversion rate × Average basket × Purchase frequency
Advertising only touches the first. The other three improve without spending a euro on campaigns — and because they multiply, small improvements produce large results.

Why small improvements produce big numbers
Here is what happens when you improve three of the numbers by 15% each.
| Today | After (+15% on three) | |
|---|---|---|
| Visitors / month | 4,000 | 4,000 |
| Conversion rate | 1.5% | 1.7% |
| Average basket | €45 | €52 |
| Purchases per customer / year | 1.3 | 1.5 |
| Annual revenue | ≈ €42,100 | ≈ €63,700 |
None of those changes needs an advertising budget. They need work in three places: checkout, basket size, and getting customers back.
Lever 1: conversion rate
This is the fastest to move, because you are already paying to bring those people in.
The two biggest causes of abandonment are hidden costs and forced account creation. The fixes, with numbers and in priority order, are in our guide to cart abandonment.
If you also need more visitors at no cost, the channel is organic search — see e-shop SEO.
The rest of this article focuses on the two levers almost everyone ignores.
Lever 2: raising the average basket
This is the most underrated number, because every euro you add falls almost entirely into margin — there is no extra customer acquisition cost.
| Tactic | How to apply it | Typical effect |
|---|---|---|
| Free-shipping threshold | 20%–40% above your average basket | The single strongest move |
| “You are €X away” indicator | A message inside the basket | Reinforces the above |
| Product bundles | 2–3 items that go together, small discount | Raises units per order |
| Suggestions on the product page | “Goes well with”, not random products | Works for complements |
| A suggestion at checkout | One small, cheap, relevant item | Low friction |
| Tiered quantity discount | 3+ units, −10% | Works for consumables |
| Gift wrap or a note | Optional, with a small charge | Good for gifts and seasons |
The free-shipping threshold is the first thing to try. How to calculate it properly, with a table by average basket, is in the article on shipping.
One caution: do not suggest a more expensive product at checkout. By then the customer has decided; the right suggestion is small and complementary, not a new decision.
Lever 3: bringing customers back
A customer who bought once costs almost nothing to sell to again — you already have their email and their trust.
The four email flows that work, in order:
| # | Flow | When | What it says |
|---|---|---|---|
| 1 | Post-delivery | 3–5 days | Thank you, usage tips, a review request |
| 2 | Complementary product | 2–3 weeks | What goes with what they bought |
| 3 | Replenishment reminder | Depends on the product | “You are probably running low” |
| 4 | Reactivation | After 4–6 months inactive | What is new, with an incentive |
The third flow is a goldmine in cosmetics, food, pet supplies and consumables. If you know your product lasts six weeks, send at five.
The three things you need to make them work:
- An email captured at checkout. Ask for it first, before the address.
- Consent for marketing communication, with its own checkbox.
- Purchase categorisation, so your suggestions are relevant rather than random.
Lever 4: trust, which multiplies the other three
An e-shop with no reviews sells less at every stage — lower conversion, smaller basket, fewer repeats.
- Product reviews on the page, with a name and date.
- Store reviews on Google, which also show in search results.
- Customer photos, if your sector supports it.
- A clear returns policy, stated before checkout.
- Real contact details and a phone number that gets answered.
How to collect reviews legitimately and systematically is in our guide to Google reviews.

Tell us what you sell and your average basket and we will propose three moves in priority order.
The 90-day plan
| Days | What you do | Which lever it touches |
|---|---|---|
| 1–15 | Measure the four numbers and record them | All |
| 16–30 | Free-shipping threshold + basket indicator | Average basket |
| 31–45 | Guest checkout + costs shown early | Conversion |
| 46–60 | Post-delivery email flow with review request | Repeat + trust |
| 61–75 | Two or three product bundles | Average basket |
| 76–90 | Complementary product flow, then measure | Repeat |
At the end of the quarter you compare the same four numbers. If two of the four moved, the plan worked.
What not to do
- Permanent discounts. You train customers never to buy at full price.
- A discount popup after two seconds. You give margin away to people who would have bought anyway.
- Five emails a week. They produce unsubscribes, not sales.
- Bundles of unrelated products. Customers notice, and you lose credibility.
- Tracking revenue only. Revenue can rise while margin falls.
Frequently asked questions
Where do I start if I have little time?
The free-shipping threshold and guest checkout. Half a day’s work, touching two levers.
How much can I realistically raise average basket?
10%–20% is achievable in the first three months with the tactics above. Beyond that needs a change in your product mix.
Do I need an email marketing tool?
Yes, but free tiers cover small lists. Pick one and stay with it for a year.
Do loyalty programmes work for a small e-shop?
Less than people think. Email flows and reviews return more for less work.
How do I know which lever to pull?
Compare your numbers against normal ranges: conversion 1%–3%, abandonment 60%–75%. Whichever is furthest off is where you start.
This week’s move
Open your last quarter’s orders and calculate two things: your average basket, and the share of customers who bought a second time.
If the second is under 20%, your biggest revenue gain is not hiding in new customers. It is hiding in the ones you already have.
