Intensell built my website for me, including the graphics and setting it up on the server. Working together was really pleasant and hassle-free. Great contact at every stage, quick replies and openness to feedback, which made the whole process much easier. We also had status meetings that were well prepared and to the point, and each stage of the project was approved as we went. I highly recommend working with this team! And on top of that, they are simply great to talk to – a relaxed but professional atmosphere. :)

What problems do I solve?

The most common barriers that make a store lose orders despite growing traffic.

Do you recognize your store in any of these points?

  1. Rising customer acquisition costs

    Ad costs keep growing, but the number of orders does not grow in proportion to your spend.

  2. Abandoned carts

    Customers add products to the cart and start checking out, but give up before completing the purchase.

  3. Weaker mobile sales

    Visitors browsing your store on their phones complete purchases less often than desktop users.

  4. Unknown reasons for drop-off

    You can see customers leaving without buying, but you don't know at which stage they quit or what stops them.

  5. Unreliable analytics data

    GA4 data doesn't match your store dashboard, and tracking gaps make it hard to assess results.

  6. Changes based on gut feeling

    You invest in changes to your store, but have no basis to judge whether they'll actually increase sales.

What can I do for you?

I use data, knowledge and experience to remove purchase barriers and grow your sales.

This is a simulation, not a guarantee of results. It assumes constant traffic and that the selected increase holds for a full 12 months. Revenue is not profit. The result does not account for seasonality or the time needed to implement changes.

What do you gain from working together?

More sales from the traffic you already have

I tap into the potential of your current visitors without constantly increasing your customer acquisition budget.

Data-driven decisions

Every change is preceded by analysis, with an effect that is easy to verify based on the results.

A clear, tailored plan of changes

I create an individual schedule and strategy tailored to your store.

Continuous growth optimization

I analyze results, implement changes and look for further areas that can improve your sales.

Working together on clear terms

A subscription with no hidden costs

You know the price before we start working together. No hourly billing and no surcharges along the way.

No long-term contracts

I don't tie you to a contract for months. We work together for as long as it brings you value.

Meetings at your pace

We agree on the schedule and frequency of meetings together. You always know what I'm doing and planning.

Still have doubts?

Let's talk about your store and find out where you can increase sales. The first consultation will show whether and how I can help you.
