Optimising your online store's conversion rate

E-commerce interface with a funnel optimised for a higher conversion rate

Your store attracts visitors, yet too few of them place an order? Your conversion rate measures exactly that: the share of visitors who complete a purchase. For a Belgian SME, improving it often pays off more than buying extra traffic. This guide covers the most effective levers, from site speed to trust, along with a method to measure every improvement.

Understand and measure your conversion rate

The formula is simple: divide the number of orders by the number of visits, then multiply by 100. Frequently quoted e-commerce averages sit between 1.5% and 3%. In other words, the vast majority of visitors leave without buying. Every extra point therefore has a direct impact on your revenue.

Before changing anything, set up reliable tracking. Configure the key steps in your analytics tool: product page, add to cart, checkout start and completed order. Then segment the data by device and traffic source. Keep GDPR in mind as well: without consent for analytics cookies, part of your visits never reaches your reports. Your conversion rate then becomes an estimate rather than a precise figure.

Speed and mobile: the hidden brakes

A slow site discourages buyers before they even see a product page. Optimise your images, use a CDN and choose high-performance hosting. Stores built with Next.js or a headless architecture generally achieve excellent loading times. Also keep an eye on Google's Core Web Vitals, which measure the speed and stability of your pages. Finally, limit third-party scripts such as chat widgets or trackers, because each one adds weight to every page load.

Smartphones also play a growing role in online shopping. Test your entire journey on a small screen: large enough buttons, short forms and a numeric keypad for phone numbers and postcodes. A shop that works poorly on mobile loses a large share of its audience.

Visitors should find the right product in just a few clicks. Structure your categories carefully, offer relevant filters (size, price, availability) and add a search bar that tolerates typos. In Belgium, bilingualism matters too: Flemish customers often expect a complete Dutch version, catalogue included.

Product pages that convince

  • Quality photos: several angles, zoom and, where possible, a short video.
  • Useful descriptions: go beyond technical specifications and explain which problem the product solves.
  • Genuine customer reviews: they reassure buyers more than any sales pitch.
  • Visible availability: show stock levels and delivery times clearly.

Simplify the checkout to lift your conversion rate

Cart abandonment remains the great plague of e-commerce: on average, close to 70% of carts never reach payment. Every unnecessary step hurts your conversion rate. To reduce abandonment:

  • offer guest checkout, with no mandatory account creation;
  • cut the number of steps to the bare minimum;
  • display delivery costs from the very start of the journey;
  • offer the payment methods Belgians expect, starting with Bancontact, then cards and PayPal;
  • send a reminder email to identified customers who left their cart, in line with GDPR.

Build trust

Trust drives sales. Clearly display your return policy, the withdrawal right set by European law, your security certificates (SSL, your payment provider's PCI DSS compliance) and your legal notice. For the Belgian market, an enterprise number (CBE), a VAT number and a local address reassure consumers. A recognised trust label, such as the BeCommerce label, can also remove any remaining doubts. Easy-to-find contact details, with a phone number and an email address that actually gets answers, show that a real team stands behind the store.

Test, measure, repeat

Improving your conversion rate never stops. Change one element at a time, for example a button label or the order of form fields, then compare results over a sufficient period. Prioritise the pages with the most traffic: a gain on the cart page matters more than a detail on a rarely visited page. Finally, log every test and its effect to build a real memory of what works.

Conclusion

A higher conversion rate comes from combining UX, content and trust. Start by measuring, fix the most visible obstacles, then keep testing.
