Wouldn’t it be great if your website not only looked good – but actually brought you clients and customers too?
Get so much more out of your website
Find out what you really need to change on your site so it finally delivers genuine business results – without pouring thousands into yet another web agency that only leaves you disappointed.

When you can’t even bear to look at your website anymore…
Every time you open your site, your stomach twists a little. This is meant to be the digital face of your business? Is this really how you want to be represented to the world?
But the worst part isn’t even how it looks. It’s that there are barely any enquiries, barely any buyers — certainly nowhere near what you hoped for. You promote your site everywhere, the visitors come… yet the results don’t.
Maybe right now you’re wondering whose fault this actually is.
It could be that you’ve already been through two or three web designers, but somehow none of them managed to create what you really had in mind.
And it’s not just the disappointment with your own site — it’s watching your competitors do just fine.
How many potential clients are slipping away to them simply because their website works, and yours doesn’t? How many leads, buyers, and customers are they taking from right under your nose, every single day?
So here’s the big question:
What does their website have that yours doesn’t?
Now picture this: a year from now, you’re still explaining to yet another web designer that you want it to be “unique”, “interactive”, or to “create a certain feeling”… Meanwhile, you’re already exhausted from the endless redesigns and the mounting costs — and your investment still hasn’t paid off.
Hello,
I’m Csilla Slezsak, designer and SEO specialist. I create websites that not only look great, but finally bring in the clients and sales you’ve been waiting for.
Websites for experts and webshop owners that are not only beautiful, but bring in clients and buyers too.
After designing and redesigning over 100 marketing-focused websites (which, by the way, adds up to about a thousand mugs of coffee…), I’ve seen exactly what makes one site attract a steady stream of enquiries and customers — while another just sits there, lonely in the forest of the internet, like a forgotten Christmas ornament in August.
Over the years, it’s become crystal clear what mistakes most business owners make when they design and build their website.


(Aside from handing the job to their cousin’s nephew who’s “good with computers”, of course.)
I’ve watched so many talented people set out to make the world better with their business — only to be disappointed when their website failed to live up to their hopes.
That’s why I put this Masterclass together: not only to show you the five most common (and costly) mistakes business owners make with their websites (spoiler: no, it’s not about flashing pink fonts) — but to give you concrete solutions, so you can finally have a website that brings you enquiries and orders.
The moment your website starts working for you
Imagine waking up one morning with a huge smile, because you actually want to check your website. You still love how it looks — and you’re proud to share it anywhere: on social media, in an email, even in a quick message.
And even better: picture your inbox filling with new sign-ups and enquiries… People you’ve never met, never even spoken to before, have found you online — and they already know you’re the right person for them.
Now, imagine how good it feels when:
- You no longer have to guess what’s working and what isn’t — you’ll know exactly what to change on your site, and why.
- Your website finally becomes a valuable tool in your business, not just a necessary evil.
- No more feeling dependent on web designers — you’ll know exactly what to request and why.
- Your site becomes an important part of your business — not just something you “like” or “don’t like”, but a tool you manage as consciously as any other part of your work.

That’s why I created this Masterclass:

“It really opened my eyes to what might be wrong with my website!”
Maybe you’re wondering…
How technical is this course? I don’t want to mess around with code.
Don’t worry — this Masterclass isn’t technical at all. It’s designed for business owners who want to understand the strategic side of websites: what makes a design work, and why some sites bring results while others don’t. No coding or programming knowledge needed. Whether you build your own site or have someone doing it for you, you’ll find it incredibly useful.
How much time will it take?
The video itself is about 50 minutes, and you can rewatch it anytime. If you do the exercises, you might spend a few hours analysing your site and writing down what to change — but you set the pace, whenever it suits you.
I already have a web designer/developer. Is this still useful?
Absolutely — even more so! You’ll know exactly what to ask for and why. Plus, the Web Designer Brief template gives you a solid base to communicate clearly and avoid misunderstandings.
What if I don’t have a website yet?
Then you’ve found this training at the perfect time. You’ll start with a clean slate and avoid the five most common mistakes from the very beginning.
What kind of websites does this apply to?
Any kind. The principles you’ll learn work across all platforms — from Elementor and Wix or Squarespace to custom solutions — because they focus on strategy and design, not the technical setup.

May I help you?
Of course, you could read all this and then do nothing. Your website will stay exactly as it is now — maybe you like it, maybe you don’t, but chances are it still won’t bring the results you’re hoping for.
You could keep trying with yet another round of web designers… or simply give up and accept that a website is just a necessary evil in your business.
Or…
You could take this Masterclass and finally understand what’s really been wrong with your site up to now. You’ll learn the mindset that lets you approach web design with marketing eyes, so you can make decisions that actually deliver real business results.
I’d love to see you in the course!
