Your team has two projects on the table this quarter. The first is a product page redesign. The second is a payment check across every device. Which one goes first?
Increasing e-commerce revenue with the same traffic: the two levers
Bringing in more people is expensive. With the same traffic, there are two ways to increase your e-commerce revenue: offer a better experience, or stop what isn't working. The first lever is the one everybody talks about. The second is rarely on the list, because no one has put a figure on what it costs. This article gives you a way to compare them in euros.
The improvement lever: offer something better
Take an example. An eyewear retailer adds virtual try-on from the phone. Customers see themselves in the frames before buying. It's useful, visible, and it makes a good story in a leadership meeting.
This lever has three traits:
- it takes several weeks of work;
- it involves design, tech teams and often the agency;
- its effect is real, but it can only be measured long after launch.
It's a good project. It's just not the only one.
The repair lever: fix what breaks
The second lever is about fixing what doesn't work for some of your visitors. It's subtler, because the site almost always works. It works for you, on your computer, in your browser.
A payment can fail on one specific phone. A button can stop responding after an update. A promo code can leak and apply far beyond its intended audience. The small piece of code installed on the site to measure your ads can stop working after a cookie banner change.
Each time, most visitors notice nothing. A minority runs into the problem and leaves. They don't write to you. They vanish from the statistics like any other visit without a purchase.
Let's do the math: redesign or repair?
The figures below are illustrative examples, not those of a real site. Replace them with your own.
Your site gets 100,000 visits a month. 2,000 people buy, with an average order value of €100. Monthly revenue is €200,000.
Lever 1, the redesign. It brings in 100 more orders a month. That's €10,000 a month. It takes several weeks of work.
Lever 2, the repair. Payment fails for 3 buyers out of 100. That's 60 lost orders, or €6,000 a month. Once the problem is found, the fix takes an afternoon.
| Monthly gain | Effort | |
|---|---|---|
| Redesign | €10,000 | Several weeks |
| Payment fix | €6,000 | One afternoon |
€6,000 versus €10,000, for a fraction of the effort. The repair earns less than the redesign. Measured against the time spent, it's by far the better investment of the two. And it pays off the very next day.
An analogy helps. Improving your driving to save a liter per 100 kilometers is a good idea. But if the tank is leaking, the first thing to do is fix the tank. The redesign is the better driving. The failing payment is the tank.
Every day without a fix has a price tag. In this example, it's about €200 a day, or €6,000 over a 30-day month.
Why the repair stays invisible
The repair matters as much as the redesign. It's missing from the project list for three reasons.
No one has put a figure on it. A redesign comes with a goal, a budget and an owner. A payment that fails for some visitors comes with no amount. Without an amount, it can't be compared with anything.
It doesn't look like a problem. Your overall conversion rate moves by a few tenths of a point. People blame the season, the weather, the campaigns. Rarely does anyone go looking for a broken payment on a single phone model.
It affects a minority. Standard alerts fire when everything stops. A problem that hits 3 buyers out of 100 doesn't take the site down. It stays below the threshold of everything you usually watch. That's what the article on brief checkout outages shows.
Your team isn't to blame. GA4, Contentsquare and the other analytics tools do their job very well: they tell you what your visitors do. They don't tell you that some of them couldn't buy, or what that costs you. Korvus complements them, as the Korvus vs GA4 comparison explains.
How to do it yourself: three habits
You can start this week, without installing anything.
1. Test the payment yourself, on several devices
Place a full order on an iPhone, on an Android phone and on a computer, with at least two browsers. Try every payment method you offer. Do it after every major site update. Note anything that blocks, even once.
2. Compare conversion rates by device
Open GA4 and split desktop, mobile and tablet. A large gap between two devices is a signal. Then look by browser. If one browser converts clearly worse than the others, a specific problem is probably hiding there.
3. Add up the small leaks
Take every anomaly you've spotted, even minor ones. Multiply the number of affected visitors by your conversion rate and your average order value. Write the result in euros per month. Add it all up. You'll get a line you can compare with the redesign.
These three habits don't replace continuous monitoring. They take time and only cover the days you apply them. But they're enough to put a first figure on the table.
What Korvus brings
Korvus monitors your site continuously. Its Sentinels spot what breaks for some visitors, put the loss in euros and alert the right person via Slack, email or SMS. Korvus alerts, your team acts: Korvus doesn't fix anything. The rest of the time, it stays quiet.
Conclusion
Increasing your e-commerce revenue relies on two levers that aren't in competition. The first, the redesign, earns a lot but slowly. The second, the repair, earns less but right away. Comparing them takes a single ingredient: a euro figure for each.
On your team's project list this week, is it mostly improvement or repair?
Frequently asked questions
How can I increase my e-commerce revenue without buying more traffic?
With the same traffic, two levers remain. The first improves the experience: product pages, journeys, new features. The second repairs what stops some visitors from buying: failing payments, unresponsive buttons, leaking promo codes. Put both in euros per month, then compare them with the effort required.
How do I know if my payment fails for some of my visitors?
Place a full order on several phones, several browsers and with every payment method you offer. Then compare the conversion rate by device in GA4. A large gap between two devices is a signal worth digging into.
Should we stop redesigns and repair first?
No. The two levers aren't in competition. A redesign is still a good project. But a repair with a euro figure attached should be able to jump the queue when it pays off quickly and takes little effort.
