@Kaen cosmetics e-shop: cost per order from Meta jumped from €12 to €18 in a month. We haven’t touched creatives or targeting. What happened?
3 tool calls · done in 46 sOn the site, not in the campaign. Three weeks ago the client made sign-up mandatory in the cart. Since then 61% of campaign visitors on mobile leave the cart, up from 38%. I’ve built 3 variations with guest checkout. Approve them and I’ll put them live on campaign traffic.

How Kaen helps
What agencies and their clients say after their first tests with Kaen.
13clients diagnosed in real time
“We use Kaen’s diagnostics to map client sites before a campaign goes live. It quickly shows us the barriers that could drag performance down and helps us set the right priorities. Then we A/B test to get the most out of the media budget.”
Vojtěch LambertCEO, LCG New Media
+18%signups
“We started with the signup flow. A few small barriers were holding signups back for no reason, and removing them gave us 18% more. Since then it’s simple: something gets flagged, we test it, we keep what works.”
Patrik ByroutiFounder, Tweenip
“
“Working with Kaen got us looking at the site continuously, hunting for the next thing to improve. Instead of one-off tweaks, we now have a clear process for raising performance over time, and testing a new idea is easy.”
Radek PřibíkCEO, Bridgemarket
+13%free-cancellation bookings
Tailor Hotels “We keep testing our offers and booking forms. The one that stuck with me: we stopped requiring a card for free-cancellation bookings, and bookings grew fast.”
Veronika B.Marketing manager, Tailor Hotels

“When you work with the product every day, it’s easy to miss what’s unclear to new visitors. Kaen helped us pinpoint where our messaging and calls to action weren’t landing as well as we thought. Now we test instead of guessing.”
Veronika NovákováHead of Customer Success, Behavera
“
“No analysis is so perfect that it doesn’t deserve an independent look, and that’s exactly where Kaen comes in. I recommend it to anyone who wants quality and insight without paying a fortune for extensive analyses.”

How it fits into your agency
Kaen does the analysis, builds the variations and runs the tests. Your team keeps the client and the final say.
- 01
Connect the client’s data
GA4 or PostHog through OAuth, read-only, under the client’s account or yours. At the start, people from Kaen set up the tracking so the numbers can be trusted.
- 02
Kaen finds the leak and builds the variations
He reads the funnel continuously, finds the step where the drop is growing, sizes what is at stake and builds the variations with the metric and run length. They land in your Slack or Teams for approval.
- 03
You approve, Kaen runs the test
The account manager approves what is worth testing in one click. Kaen runs the A/B test for the client and scales the winner. Nothing changes on the client’s site without your yes.
- 04
Measure and report
Kaen evaluates the test from the same data and writes up what came out. You put the result in the report next to the campaigns: this test lifted checkout conversion, here is the proof.
Plugs into the data you already have
Kaen reads the client’s analytics, ad accounts and session recordings, read-only. Nothing to rebuild on the client’s site.

A whole CRO team for your agency
Four roles you would otherwise have to hire. They work alongside your account managers and specialists, not instead of them.
Data analyst
Checks every client’s data daily and speaks up when the tracking your reports rely on breaks.
UX researcher
Watches how people from your campaigns move through the client’s site and finds the step where they drop off.
CRO specialist
Puts a number on every leak and builds the variations that test the fix.
Growth manager
Evaluates the result, ships the winner once approved and writes up what you can send the client.
What your agency gets
More results for the client, more work for you
The ceiling on campaigns is often not in the auction but on the website the campaigns send people to. That’s where Kaen works.
Campaigns get room to scale
When the site converts better, the cost per lead drops. The same budget brings more customers, and the client has a reason to raise it. You keep moving the client forward even after the campaigns are tuned.
Deeper insight for the campaigns too
Kaen sees what happens after the click: which landing page, segment or device loses people. That is input for targeting, creatives and budgets you won’t get from the ad platforms.
Extra work you can invoice
Every winning test opens follow-up work: copy, design, a bigger change to the site. Those are hours of your team the client isn’t buying today. Kaen finds them, you deliver them.
A client who is harder to lose
Results stop depending on the auction alone. The client keeps getting new tests and proven results, and a retainer that brings proof is much harder to cancel.
Senior CRO without the hire
An analyst who can read a funnel and design an honest test is expensive, and the work comes in bursts. Kaen covers that role for every client at once, from day one.
Proof that wins the next client
Every finished experiment is a case study: what changed, by how much, with what confidence. Exactly what holds up in a tender and in the first meeting with a new client.
FAQ
Will Kaen replace people at our agency?
No. Kaen builds and runs the tests, your team decides. Every variation waits for the account or project manager’s approval before it goes live. Kaen adds a role you don’t have on the team today and frees up the people you do have for the client.
What do you need from the client to start?
Read access to analytics (GA4 or PostHog) and to the ad accounts you run for the client. If tracking is missing or doesn’t add up, we fix it during setup.
Who ships the changes on the client’s site?
Kaen. Once you approve the variations, he runs the A/B test and rolls the winner out to all visitors. Bigger changes beyond a test stay with a developer, yours or the client’s. Nothing ships without your approval.
What happens to the client’s data?
Kaen only reads it and uses it solely to analyze that client’s site. Nothing is trained on it, it’s encrypted in transit and at rest, and one client’s data is never used for another. Details on the Security page.
Can we sell Kaen under our own brand?
Yes. Outputs can go to the client under your brand or co-branded. Kaen invoices you, the client stays yours.
Which clients is it right for?
Clients with real traffic on the step you want to improve, and working tracking or the willingness to fix it. A client with no traffic needs campaigns first, a client with broken tracking needs it fixed first. We’ll tell you straight.
How much does it cost?
We agree partner terms based on the number of clients. On the demo we’ll work out what it comes to for yours. Get a demo →
