John Komarek Founder & Conversion Expert

In fact, over the last couple of years, we have helped more than 71 ecommerce businesses boost their sales by up to 183.5%.

How did we do it?

You know increasing ecommerce conversions can be very challenging. There are many “best practices” out there but blindly following them won’t help.

If you want to beat your competitors, you need to provide a better shopping experience that focuses on your niche market. It’s even more important for mobile shoppers than ever.

Your biggest advantage is understanding your customers and improving your online store to help them purchase the perfect product.

And that’s exactly what we’ll do for you – make your customers fall in love with your online store and spend more money.

You may ask…

What makes us different?

From the very beginning, we have always wanted to help ecommerce companies grow online sales. Generating traffic is easy these days but it takes a lot of work to convert them into customers.

It’s the most difficult task in any ecommerce business. But because we love challenges and mobile user experience, optimizing online stores became our obsession.

Here’s the kicker:

You can do everything right when building your business. But if your online store experience is terrible, you’ll likely lose many customers that had a potential to buy your products for years to come.

The good thing is that you already have a plenty of data about your customer shopping behavior. What you need now is an expert who can convert these insights into an actionable plan.

Let me give you 3 great reasons why we will change the way you sell online:

  • We’re Data-Driven – It isn’t a buzzword for us; it’s who we are. Every improvement, every recommendation you’ll get from us is backed with data about your customers’ shopping behavior. We’ll find and address all their concerns, doubts, and hesitations.
  • Ecommerce Focus – Many CRO agencies serve multiple industries – SaaS, lead-gen websites, etc. We only work with ecommerce businesses because we understand the specific requirements when it comes to increasing actual online sales, not just form submissions.
  • Personalization Engine – We created our own ecommerce personalization engine that is driven by Artificial Intelligence. It allows us to personalize every step of your customer purchase journey and make sure they always see only relevant offers.

Charlie ToddMarketing Manager,

We have worked together for a number of years now and John has helped us completely transform our e-commerce site and improved all our KPIs. John takes an invested, hands-on approach to his work and he’s really passionate about it.

Wendee LeeDirector,

The conversion analysis provided by Pixelter has been the most thorough and relevant audit I have ever received. The information provided was invaluable in delivering a much higher quality user experience and in turn a noticeable increase in conversions. Not only do I highly recommend Pixelter for any e-commerce business but I believe it to be a necessity.

Claire SimonDirector,

We tried to do many changes to increase mobile sales, but nothing really helped until we started to work with John. His team delivered the expertise we needed. They took the time to understand our business and rebuilt our mobile site to make it easy to use and to communicate our brand values. We saw great results in our conversion performance.

Patrick CrowleyDirector,

The audit of our store was very insightful. We didn’t know what to expect but John discovered 50+ issues and opportunities on our site. He also explained the best solutions to fix them. It helped us to improve our mobile experience and get the most of our holiday shopping season. Very happy with the results.

Dan ToffelDirector,

At first, we didn’t think we had any major issues but Pixelter’s audit revealed so many of them. They rebuilt our checkout process and the conversions almost doubled compared to before.
