Conversion Rate Optimization Services

No matter how many people visit your site, it's more important how many of them convert. Our conversion rate optimization services help you turn visitors into customers through smart UX/UI improvements of your site or app.

Why is your website so important?

When you invest in customer acquisition, everything depends on your website. If it’s not optimized to convert, you lose money — paying for visitors who never become customers.
Users leave due to difficult buying processes, unclear navigation, or poor experience. And that’s a Conversion Rate Optimization (CRO) to solve this.

CRO services: real-world examples

Optimizing conversion rates for the Samsung Experience Store

Before: The heatmap indicates that users frequently click on the installment option, which demonstrates their high interest in this feature; however, distracting labels diverted attention from the product itself.
After: Optimizing conversion rates, we highlighted the minimum monthly installment to present the cost better, inform purchase decisions, minimize friction, and encourage users to complete their purchase.
Result:
The minor but significant adjustment resulted in an 18% increase in conversion from the product page to the shopping cart.

CRO services for the Fotoklok project:

Before: The interface analysis found the header cluttered and confusing. Navigation, especially the mobile one, was poor due to clunky submenus and missing essential trust elements.
After: A streamlined, transparent header provides intuitive navigation. Key actions are easily accessible, submenus function smoothly, and thumbnails aid location.
Result:
UX/UI changes across key website pages, including this one, drove a +25% rise in conversions.

Pop-up cart optimization for Infoshina

Before: The cart page had two calls-to-action: “Continue shopping” and “Checkout.” However, the “Checkout” button was insufficiently prominent, which led to high drop-off rates at this stage.
After: The “Continue shopping” button was removed, and the “Checkout” button color was changed to make it noticeable to direct users to the next step.
Result:
 These minor UI adjustments resulted in a 14.8% improvement in the conversion rate from the cart page to the checkout page.

Conversion rate optimization service for Shiny&Diski

Before: Heatmaps showed that users frequently clicked on the model to check available sizes.
After: Clearly visible model size availability eliminates the need for users to search for this information.
Result:
This change made conversion go up by 12%. Another big effect is that users are more likely to buy things because they can make decisions faster.

The Turum-burum team helped us to launch a brand-new Web 3 product to the market very fast. It took them less than a month to create all the design mockups and met all the deadlines. I liked the level of professionalism and way of communication they provided. There were no problems later with design implementation because a designer considered all the design elements and statuses in the mockup.
