5 mistakes killing your e-commerce conversion rate

Discover the 5 most common mistakes that drop e-commerce conversion rates and how to fix them quickly.

An e-commerce site that generates traffic but doesn't convert is like a store with lots of visitors but no open registers. Here are the 5 most common mistakes we see before we step in.

1. A checkout that's too long and complex

Each additional step in the purchase funnel loses between 10% and 25% of potential buyers. The golden rule: 3 steps maximum (cart → information → payment).

Solutions: offer guest checkout, pre-fill fields when possible, display a progress bar.

2. A neglected mobile experience

In Switzerland, over 60% of e-commerce traffic comes from mobile. Yet many online stores are still primarily optimized for desktop.

Solutions: systematically test on mobile, enlarge touch targets, simplify mobile navigation, optimize images for speed.

3. No visible social proof

Customer reviews, ratings, trust badges and testimonials are the first things buyers look for before ordering. Without them, trust doesn't build.

Solutions: integrate Google Reviews, display reviews directly on product pages, add secure payment badges.

4. Slow loading times

Every additional second of loading time reduces conversion rate by 7% on average. An e-commerce site must load in under 3 seconds on mobile.

Solutions: optimize images (WebP, lazy loading), use a CDN, minimize JavaScript, cache static resources.

5. No upsell or cross-sell strategy

Not suggesting complementary products or upgrades means leaving money on the table. Smart recommendations can increase average cart value by 20% to 40%.

Solutions: "Customers also bought", product bundles, discounts from a minimum amount, free shipping above a threshold.

In summary

Fixing these 5 mistakes doesn't require a complete redesign. They're often targeted optimizations that can double your conversion rate in just a few weeks.
