Evidence-based e-commerce consulting
Online shops that convert.
Built on proven research, not opinion.
Most online shops don't have a traffic problem. They have a conversion problem. Visitors hesitate, lose confidence, or can't find what they need, and they leave.
If your shop already converts well and you test and improve continuously, keep going. But if your conversion is poor, or just "okay," and you want to turn more visitors into buyers, that's where I come in.
I translate trusted e-commerce research into clear, actionable improvements so your shop converts better before you spend more on ads or start testing.
The questions I get asked most.
Why are people visiting my online shop but not buying?
You can see the traffic in your analytics, but the sales aren't following. I identify the specific moments where shoppers drop off so you fix the right things, not just the obvious ones.
Why didn't our relaunch improve sales?
A relaunch changes how your shop looks, it doesn't automatically remove the friction stopping shoppers from buying. I find what structural issues survived the rebuild so your investment finally shows up in your conversion rate.
How do I increase sales without increasing my ad spend?
Sending more traffic to a shop that isn't converting just scales the loss. I improve what happens after the click so your existing traffic works harder.
How I work
A lot of conversion problems are already solved. You just need to know where to look.
Around 7 out of 10 shoppers leave without buying even on well-designed shops built on best practices because friction remains at the moments that matter most.
Large-scale usability research has studied these drop-off patterns across hundreds of online shops and millions of shopping sessions. The answers to most conversion questions already exist, and the world's highest-performing retailers don't wait for a test to confirm them. They apply that research directly, alongside testing, to inform their decisions every day.
I apply that research to your shop, so your decisions are based on what shoppers actually do not on what someone assumes they might do.

How I can help
Different ways to work with me, all based on evidence.
Online Shop Audits
Expert review of your online shop.
A structured, expert-led review of your shop, from first impression to post-purchase. Every finding is grounded in research. You get a prioritised roadmap of what to fix first and why it matters. And because a report in a drawer changes nothing, I can stay involved afterwards to turn each finding into real improvements.
Project Consulting
E-Commerce project guidance.
I join your team as an external project consultant for launches, rebuilds or improvement programmes, and bring evidence-based guidance into every key decision. No guesswork. No reinventing wheels that research already built.
Workshops
Design and build it right, based on what research already knows.
In the workshops you’ll get a structured overview of the most important evidence-based e-commerce improvements how to design and build the features that determine whether shoppers buy or leave. Concrete, directly applicable knowledge you can use from the next project onwards.

The evidence-based e-commerce consultant
Hi, I'm Claudia!
For more than twenty years, I've worked in digital and e-commerce, from my first major project with Austria's largest grocery retailer in 2015 to managing international shop launches across twelve-plus countries.
And in every single project, the same questions came up.
Should checkout be one long page or several steps? Do trust badges actually lift conversion, or just clutter the page? How do you build a product page that makes people commit?
Nobody had a real answer. We had best practices. We had opinions. We had whatever the most senior person in the room preferred. But we rarely had evidence.
So I started digging. Usability studies. Large-scale research into how shoppers actually behave. The answers existed. They just weren't where most teams were looking.
In 2025, I turned that into my own practice. I'd spent years watching shops make the same preventable mistakes and I wanted to do something about it.
Most conversion problems are friction problems. They've been studied. The solutions already exist. You shouldn't have to solve them from scratch every time, and you shouldn't have to test your way to an answer that was already documented somewhere.
That's what I'm here for.

Why work with me
Why e-commerce teams choose to work with me.
Experience through 28+ website and online shop projects.
Including my own online shop and an international marketplace rolled out across 12+ countries. Agency side, brand side, founder side, I've been on every side of the table.
A research translator, not a guesser.
Every recommendation is grounded in large-scale usability research from leading institutes like Baymard and Nielsen Norman Group. Not personal opinion.
Projects accross different sectors.
The same conversion fundamentals apply everywhere, but the context is never identical. Sectors include grocery retail, energy, automotive, fashion, finance, NGO and international marketplace platforms.
Foundation first, then testing.
I get your shop's structure right before you spend a cent on tests or ad budget. So when you do test, you're optimising what actually matters.
From diagnosis to implementation.
I don't just hand over a report. I help prioritise findings, align stakeholders and make sure recommendations turn into real changes in your shop, not a document that gets filed away.
Independent guidance, always.
No platform partnerships. No referral incentives. No preferred tools to push. The only thing shaping my recommendations is what the research says works.
