Conversion optimisation for online stores. Turn more visitors into customers.
We analyse, design and improve with a clear purpose, using established psychological principles, real user insights and the improved one-page checkout in PrestaShop 9.2.

02Purposeful use of psychological principles
03Data-led testing instead of guesswork
04Improved one-page checkout from PrestaShop 9.2
More traffic achieves little if visitors do not become customers.
Many stores invest heavily in advertising, yet the main obstacle is often not traffic, but the store itself. Unclear processes, too many competing messages or missing guidance cause potential customers to leave, often just before buying.
Conversion optimisation addresses these issues with better user journeys, psychological clarity and design that supports sales as well as looking good.
A small change can make a big difference: an increase of just one percentage point in conversion rate can improve revenue and profitability, without increasing your advertising budget.

Marketing without CRO is often unprofitable. Conversion optimisation is central to scalable growth.
Understand how users think, then respond effectively.
Good conversion optimisation relies on clear principles, not assumptions. We apply established effects from behavioural psychology where decisions are made, from the first click to checkout.
We test regularly and observe user behaviour through heatmaps and tracking. We then adapt design, content and processes to guide users without overwhelming them.
We apply these principles subtly, purposefully and in context, so design is effective as well as attractive.

Fewer clicks. More completed orders. The one-page checkout.
A checkout that is too long, technically unreliable or difficult to use on mobile costs orders, often at the final step. Since PrestaShop 9.2, an improved one-page checkout is included as standard: focused on the essentials, logically structured and as streamlined as Shopify, supporting strong conversion.
We configure it for your store and refine the details that matter: clear focus, fewer distractions, reassurance at the right moment and an easy checkout experience.
Your benefit: higher completion rates from the same traffic. The one-page checkout is GDPR-compliant, responsive and compatible with common payment methods.
Conversion is a structured process, not a matter of chance.
Every store, audience and sector is different. We use thorough analysis, focused tests and psychologically informed UX improvements tailored to your goals and systems, rather than rigid templates.
Whether you want more leads, more purchases or fewer people leaving, we help with a transparent, data-led approach and measurable results.

Questions about conversion optimisation? We have answers.
What does conversion optimisation actually achieve?
Even small improvements to copy, structure or processes can noticeably increase completion rates, often directly affecting revenue and profitability.
Do I have to redesign the whole store?
No. We improve the areas where it makes sense. A few considered changes to CTAs, checkout or product presentation are often enough. For older or poorly designed stores, a complete redesign may be worthwhile.
How do you measure success?
With KPIs such as conversion rate, click paths, time on site and A/B tests. Results are documented transparently.
Which ecommerce platforms do you support?
We optimise PrestaShop, Shopware and Shopify stores, taking each platform’s technical characteristics and behaviour into account.
How much does conversion optimisation cost?
It depends on scope. We offer one-off analyses and ongoing optimisation support, with transparent, individual pricing.
How long before results become visible?
Initial improvements are often visible within a few days. Allow two to six weeks for valid A/B tests or structural changes.
