Same business, different website, different revenue: +217,348 CZK per month
A Czech e-commerce store in the health and beauty segment. Same product, same SKU range, same owner. In the first 30 days after replacing the website and rolling out a new marketing system: traffic +29%, conversion rate +102%, revenue +143% (+217,348 CZK per month) — at the same ad spend. This article breaks down the four interventions that made it possible and the three conditions without which the same system would have delivered far less.
The owner came to us with a familiar frustration: revenue stagnating, ads requiring more and more budget for the same number of orders, conversion stuck around one percent. The product was solid and customers were returning. The problem sat somewhere between visit and purchase — and also between first and second purchase, which the company had never measured.
The first 30 days after launching the new system looked like this:

Honest caveat
This is the first month after launch, when the effect of new ad campaigns, retargeting, and email sequences is at its strongest. The real long-term average for this client settled between 75% and 95% revenue uplift — still a multiple of what a redesign alone would deliver. The point of this study is to show what's realistically possible, not to guarantee the same number for every client.
What "different website" means in these numbers
"Different website" here doesn't just mean a new design. It means a new business system built around the e-shop. That distinction matters — and explains why a redesign on its own delivers a fraction of these results at other companies. The website is just the platform. The revenue comes from how you build acquisition, service, and customer return around it.

A 29% traffic lift is decent, but on its own it would only deliver a quarter of the revenue gain. The real breakthrough was the conversion rate, which more than doubled. And that came from specific interventions, not luck.
Four interventions that lifted conversion by 102%
Instead of just redrawing the pages, we built four systems around the e-shop that work together. Each of them addresses a specific point in the customer journey — from the first click to the second order.
Order value
Upsell and cross-sell in the cart
A customer who is already buying is in purchase mode. It's cheaper to convince them to add a related product than to acquire a new customer. We added thoughtful recommendations to the cart and product page — complementary products and upgrade versions — that show up at the right moment, not aggressively.
+ higher order valueCustomer lifetime value
Repeat-purchase campaigns
A new customer costs the company several times more in ad spend than getting a second order from an existing one. We set up promotional mechanics aimed at the existing customer base: seasonal offers, second-order bonuses, recommendations to top up long-term skincare routines. The result — the customer doesn't disappear after the first purchase but comes back regularly.
+ LTV per customerTraffic quality
New creatives and a retargeting funnel
The ad creatives were worn out, CTR was dropping month by month, and Meta's algorithm was finding lower-quality audiences. We produced new visual creatives, built a retargeting funnel (viewed → added to cart → abandoned → completed), and pointed algorithmic optimization at actual purchases, not clicks.
+ higher conversion from adsRetention
Email marketing as the second engine
The store had thousands of contacts in its database but communicated with them sporadically. We launched automated sequences — abandoned cart, post-purchase care, re-engagement for inactive customers, seasonal newsletters. After one month, email marketing became the second-biggest revenue channel after direct traffic.
+ new revenue channelA website redesign alone, in our experience, lifts conversion by 20–30%. The combination with upsell, retention, and functional advertising is what turns a redesign into a full investment that doubles revenue.
Why the same system might not deliver the same result for you
This is the part most case studies skip. One successful case doesn't set a rule. For this e-shop, three conditions held — without them the result would have been substantially weaker:
- It had enough traffic to optimize. 6,578 monthly sessions give you a statistically meaningful base for measurement. With 300 visits the same system would still work, just be hard to evaluate in a short window.
- It had a product the market actually wants. The store's catalog is competitive on price and quality. If the product isn't compelling on its own, no marketing system fixes that.
- The owner was willing to invest post-launch. The difference between a project that lifts revenue 30% and one that lifts it 130% lives in the first six months after launch: iteration, A/B tests, reacting to data. Without that, the system freezes.
If any of these conditions don't hold, a redesign delivers a smaller effect. That's why before starting any project we run a short diagnostic that shows whether your business is in a state where investing in a website and marketing actually makes sense.
Three questions to answer for yourself first
01How many people visit your website per month?
If under 1,000, we start by driving traffic — a redesign without traffic is premature. Above 3,000 you have room to work on conversion.
02What is your conversion rate?
Czech-market guidance: e-commerce 1–3%, services 2–5%, clinics 3–6%, local services 4–8%. Below the band means your website is dragging results. Inside or above the band — investment elsewhere returns more.
03How many of your orders come back for a second purchase?
If under 15%, you don't have retention set up and that's where you're losing the most money. Here the combination of email marketing, upsell, and LTV campaigns has the biggest impact — often bigger than the redesign itself.
Losing this much too?

Calculate my lossesBottom line
The numbers in this case aren't a guaranteed minimum. They're proof of what's possible when you add cart upsell, repeat purchase, better advertising, and email on top of a redesign. Each of those pillars works on its own. The real heartbeat, though, comes from the combination — website as platform, marketing as engine, data as steering wheel.
If this logic resonates and the answers to the three questions suggest there's room for a similar shift in your company, the next step is simple: work out the exact number and decide based on that — not on a feeling, not on an article, not on the experience of one of our clients.
Frequently asked questions
What does "different website" actually mean in this case study?
Not just a new design. It means a new marketing system built around the e-shop — upsell and cross-sell in the cart, repeat-purchase campaigns, a retargeting funnel, and email marketing. A redesign alone, in our experience, lifts conversion by 20–30%. The combination of all four pillars delivered +143% revenue per month.
Can I expect the same revenue lift on my own e-shop?
There is no guarantee. The first month after launch is usually the strongest because of the novelty effect from new ad creatives and email automations. The real long-term average for this client settled between 75% and 95% revenue uplift — still several times what a redesign on its own would deliver. Your result depends on baseline traffic, product competitiveness, and willingness to invest in post-launch iteration.
Does this approach work for small sites with low traffic?
It works, but the results are harder to measure. With 300 monthly visits the same system would still raise conversion and LTV — it would just take several months to see a statistically meaningful trend. Below 1,000 visits per month we recommend driving traffic first. Above 3,000 you have room to optimize conversion.
Which intervention drove the biggest share of the revenue lift?
The conversion rate — from 1.09% to 2.20%, i.e. +102%. Traffic only grew by 29%, so traffic alone would have delivered just a quarter of the result. The real breakthrough came from the combination of a better website (more orders from the same traffic), upsell (higher order value), and repeat purchases from email (more orders from existing customers).
What is an average conversion rate in the Czech market?
By segment: e-commerce 1–3%, professional services 2–5%, private clinics 3–6%, local services 4–8%. If you're below the lower bound, the website is likely holding you back. Inside or above the band, a redesign returns less marginal value and it makes sense to focus on other levers — retention, LTV, or acquisition.
How long does it take to see the first results?
The first month is usually the strongest — the novelty effect of new ad creatives and email automations. Stabilization happens between months 3 and 6, when the long-term average settles in (typically 75–95% revenue uplift). Without post-launch iteration (A/B tests, reacting to data) the system freezes at the first-month level and gradually decays.
